INTRODUCTIONThe X-65 is the latest member of the Lowrance family that combines a highperformance sonar with a wide screen. Using menu features and “soft-key” operation, the X-65 is also one of the easiest to use sonars thatLowrance® has ever built. The wide “Clearvision” screen shows theunderwater world with high resolution and detail. The display and key-board are also lighted for night operation. The X-65 has digital boat speed,surface water temperature, and distance travelled (log) screens.

NOTICE!The storage temperature for your unit is from -4 degrees to +167degrees Fahrenheit (-20 degrees to +75 degrees Celsius). Extendedstorage in temperatures higher or lower than specified will damage theliquid crystal display in your unit. This type of damage is not coveredby the warranty. For more information, contact the factory's CustomerService Department or your local service center.

INSTALLATIONMOUNTINGInstall the X-65 in any convenient location, provided there is clearancebehind the unit when it is tilted for the best viewing angle. Holes in thebracket base allow wood screw or through-bolt mounting. You may needto place a piece of plywood on the back of thin fiberglass panels to securethe mounting hardware. Make certain there is enough room behind the unitto attach the power and transducer cables.

The X-65's gimbal bracket will also accept the GBSA-1 swivel bracketadapter that lets you rotate the unit a full 360°.

The smallest hole that allows one power or transducer connector to passthrough is 3/4". After the hole is drilled, push the transducer connector upthrough the hole first, then drop the power cable down through it.

POWER CONNECTIONSThe X-65 works from a twelve-volt battery system. For the best results,attach the power cable directly to the battery. You can attach the powercable to an accessory or power buss, however you may have problemswith electrical interference. Therefore, it’s safer to go ahead and attach thepower cable directly to the battery. If the cable is not long enough, splice#18 gauge wire onto it. The power cable has two wires, red and black. Redis the positive lead, black is negative or ground. Make certain to attach thein-line fuse holder to the red lead as close to the power source as possible.For example, if you have to extend the power cable to the battery or powerbuss, attach one end of the fuse holder directly to the battery or powerbuss. This will protect both the unit and the power cable in the event of ashort. The X-65 Plus requires a 3-amp fuse.

IMPORTANT!Do not use this product without a 3-amp fuse wired into the power cable!Failure to use a 3-amp fuse will void your warranty.

If you’re installing a speed/temperature sensor, read it's mounting instruc-tions. Route the sensor’s cable to the X-65's power cable and plug it intothe connector marked “SPEED/TEMP CABLE”

After the cables have been routed, fill the hole with a good marine sealingcompound. Offset the bracket to cover the hole. Route the power cablethrough the slot. Break out one of the holes in the back of the bracket forthe transducer cable.

TRANSDUCER INSTALLATIONSome X-65s are packed with a HS-WSBK transom mount transducer. Itcan be installed on any outboard or stern-drive (inboard\outboard) pow-ered boat. It can also be permanently installed inside the boat to "shoot-through" the hull on some fiberglass boats.

The “kick-up” mounting bracket helps prevent damage if the transducerstrikes an object while the boat is moving. If the transducer does “kick-up”, the bracket can easily be pushed back in place without tools.

Read the transducer's installation manual carefully before attemptingthe installation. Determine which of the mounting positions is right foryour boat. Use extreme care if mounting the transducer inside the hull,since once it is epoxied into position, the transducer usually can't beremoved without damaging it. Remember, the transducer location is themost critical part of a sonar installation. If it isn't done properly, thesonar can't perform to its designed potential.

Full ChartThis is the default mode used whenthe X-65 is first turned on. The bottomsignal scrolls across the screen fromright to left. Depth scales on the rightside of the screen makes it easy todetermine the depth of fish, structure,and other objects. The line at the topof the screen represents the surface.The bottom depth shows at the top leftcorner of the screen. The word "AUTO"at the screen's top center shows thatthe X-65 is in the automatic mode,freeing you from sensitivity, range, and noise rejection adjustments.

Split ChartA split chart shows the underwaterworld from the surface to the bottomon the right side of the screen. The leftside shows an enlarged version of theright side. The zoom range shows atthe bottom of the screen. In this ex-ample, the zoom range is 2X, or twotimes the right side's view. By press-ing the ZOUT and ZIN keys, you canchange the left side's zoom from 2X to4X and back.

Digital/ChartThe digital/chart shows the chart onthe right side of the screen. The leftside has four digital boxes containingthe water depth at the top of thescreen, boat speed, distance trav-elled (log), and surface water tem-perature. At the bottom of the screenis a temperature graph. (Note: Speed,distance, and temperature displaysrequire a speed/temperature sensorwhich comes with the X-65 Plus andmust be purchased separately for theX-65.)

9

Window GroupsYou can change the displays on the X-65 by using the windows feature. Thislets you use different displays for yourown fishing or boating situations. Thisfeature gives you 8 different displayscreens in the window groups alone.

The screens available in the windowsmode are divided into two or morewindows per screen. Each screen ofwindows is called a “group”. Group “A”as shown above has the digital depthdisplay in one window, battery voltagein another, water temperature, speed,and distance travelled.

To use the windows feature, first pressthe MODE key. A screen similar to theone shown at right appears. Highlightthe "Group" menu at the bottom of thescreen. Now press the left or rightarrow keys to sequence through theavailable groups. When the desiredgroup appears, press the EXIT key toerase the modes menu.

10

AUTOMATICWhen the X-65 is first turned on, theAutomatic feature is enabled. This isindicated by the word “AUTO” at thetop of the screen. The Automatic fea-ture adjusts the sensitivity and rangeso the bottom signal is displayed in thelower half of the screen at all times.

To turn Automatic off, first press theMENU key, then press the up or downarrow keys until the "AUTO" menuappears. Press the left arrow key toswitch to the manual mode. The letters “Man” appear at the top of thescreen, indicating the unit is in the manual mode. To turn Automatic on,repeat the above steps to get the auto menu, then press the right arrowkey.

SENSITIVITYThe sensitivity controls the ability of the unit to pick up echoes. A lowsensitivity level excludes much of the bottom information, fish signals, andother target information. High sensitivity levels enables you to see thisdetail, but it can also clutter the screenwith many undesired signals. Typi-cally, the best sensitivity level showsa good solid bottom signal withGrayline and some surface clutter.

When the X-65 is in the Automaticmode, the sensitivity is automaticallyadjusted to keep a solid bottom signaldisplayed, plus a little more. This givesit the capability to show fish and otherdetail.

However, situations occur where itbecomes necessary to increase or decrease the sensitivity. This typicallyhappens when you wish to see more detail, so an increase in sensitivityis indicated. The procedure to adjust it is the same whether the unit is inthe automatic or manual mode.

To adjust the sensitivity, press the MENU key, then press the up or downarrow keys until the "SENS" menu appears as shown above.

11

The sensitivity menu has left and right arrows, plus a horizontal bar graph.The graph gives a visual indication of the sensitivity level. The number tothe right of the bar graph shows the percentage of sensitivity in use.

To increase the sensitivity level, press the right arrow key. As you pressthe key, the menu’s bar graph will grow wider and the percentage willincrease in value. You can also see the difference on the chart record asit scrolls. When the sensitivity is at the desired level, release the key.

To decrease the sensitivity level, press the left arrow key. The bar graphand percentage will decrease. When the sensitivity is at the desired level,release the key. When you reach either the maximum or minimum limit,a tone sounds.

To erase the menu, press the EXIT key.

RANGE - AutomaticWhen turned on for the first time, theX-65 automatically places the bottomsignal in the lower half of the screen.This is called Auto Ranging and is partof the automatic function. Typically,the range cannot be changed manu-ally while the unit is in automatic, asshown at right. However, dependingupon the bottom depth and the currentrange, you can change the range to adifferent depth. In the example screenshown below, the bottom depth hasdescended to a point where you can change the range to 150 feet. To dothis, simply press the right arrow key while the Auto Range menu isdisplayed. When you're finished withthis menu, press the EXIT key toerase it.

RANGE - ManualThe X-65 gives you complete controlover the range when it’s in the manualmode.

To change the range, first make cer-tain the X-65 is in the manual mode.Next, press the MENU key and the upor down arrow keys until the range

12

menu appears as shown at right. Pressthe left or right arrow keys to decreaseor increase the range. The availableranges are 0-5, 10, 20, 30, 40, 60,100, 150, 200, 300, 500, 800, and1000 feet. After the desired range isdisplayed, press the EXIT key to erasethe range menu.

NOTE: The depth capability of the X-65 depends on the transducer instal-lation, water and bottom conditions,and other factors.

UPPER AND LOWER LIMITSYou can enter any range when the unit is in the manual mode. The X-65lets you enter any upper and lower limit, provided there is at least ten feetseparating them. (On the screen below left, the upper limit is 0 and thelower limit is 100.) Using the upper and lower limit range option, wechanged the range from 0 to 100 feet to 35 to 65 feet. This "zoomed" thedisplay to a 30 foot range.

As you can see, the fish arches near the bottom are much larger and easierto see. In fact, a possible fish on the bottom shows on the enlarged screenthat is not even visible on the left! Not only does this make it easier to seetargets, but you can more accurately determine their depth, due to theexpanded depth range.

To change the upper and lower limits, first press the MENU key. Next,make certain the X-65 is in the manual mode, then press the up or downarrow keys until the "Set Chart Limits" menu appears as shown at the topof the next page.

13

Now press the left arrow key to change theupper limit or the right arrow key to changethe lower limit. A screen similar to the onebelow appears.

In this example, we're setting the upper limit.Use the up and down arrow keys to select thenumber, the right and left arrow keys to moveto the next number. When the limit shows thedesired depth, press the ENT key. The screenshown below appears.

As you can see, the upper limit has changedfrom 0 to 35 feet. If you want to change thelower limit, repeat the above steps, press theright arrow key on the "Set Chart Limits"menu, and change the lower limit to thedesired value.

ZOOM“Zooming” the picture is a common methodused to enlarge small detail and fish signals. The X-65 gives you twodifferent zoom sizes, plus a split screen zoom option. The zoom operationand adjustment is different in the automatic and manual modes.

ZOOM - AUTOMATIC MODEThe only way to zoom the screen in automatic mode is to simply press theZIN (zoom-in) key. This enlarges all echoes on the screen to twice theirnormal size. If you press the ZIN key again, the screen is "zoomed" to fourtimes normal size. To return the screen to 2X or normal, simply press theZOUT (zoom-out) key until the desired zoom appears. When the X-65 isin the 2X or 4X zooms, "2X" or "4X" appears in the lower right corner ofthe screen, showing the current zoom mode.

14

ZOOM - MANUAL MODEThe Z-IN (zoom-in) and Z-OUT (zoom-out) keys enlarge and reduce thesize of the echoes on the screen when the unit is in the manual mode, thesame as the automatic mode.

However, you can manually adjust thezoom when the unit is in the manualmode. To do this, press the MENUkey, then press the right or left arrowkeys until the "CHART ZOOM" menuappears. Now press the right arrowkey. A screen similar to the one atright appears.

This is the split-screen zoom menu. Azoom bar shows at the far right side ofthe screen. All echoes between thetop and bottom of the zoom bar areshown on the left side of the screen. Pressing the up or down arrow keysmoves the zoom bar up or down. As you adjust the zoom bar, the rangechanges on the left side of the screen at the same time.

To return to the full-screen mode, simply press the EXIT key. This alsoerases the zoom bar and move zoom menu.

GRAYLINE®

GRAYLINE lets you distinguish between strong and weak echoes. It“paints” gray on targets that are stronger than a preset value. This allowsyou to tell the difference between a hard and soft bottom. For example, asoft, muddy or weedy bottom returns a weaker signal which is shown witha narrow or no gray line. A hard bottom returns a strong signal whichcauses a wide gray line.

If you have two signals of equal size, one with gray and the other without,then the target with gray is the stronger signal. This helps distinguishweeds from trees on the bottom, or fish from structure.

GRAYLINE is adjustable. Since GRAYLINE shows the difference be-tween strong and weak signals, adjusting the sensitivity may require adifferent GRAYLINE level, also. The level chosen by the X-65 at power onis usually adequate for most conditions. Experiment with your unit to findthe GRAYLINE setting that’s best for you.

To adjust the GRAYLINE level, press the MENU key, then press the up

15

or down arrow keys until theGRAYLINE menu appears. A screensimilar to the one at right appears.Press the left arrow key to decreasethe gray level or the right arrow key toincrease it. The percentage ofGRAYLINE in use changes as thearrow keys are pressed. The bar chartalso gives a graphical indication of theGRAYLINE level. You can see thechange on the screen (both on themenu and on the chart record) as youpress the keys. After you’ve finished,press the EXIT key to erase the menu.

CHART SPEEDThe rate echoes scroll across the screen is called the chart speed. It’sadjustable by first pressing the menu key, then pressing the up or downarrow keys until the "CHT SPD" (chart speed) menu appears as shownbelow left. Increase the chart speed by pressing the right arrow key ordecrease it by pressing the left arrow key. The percentage of chart speedin use changes as the arrow keys are pressed. The bar chart also givesa graphical indication of the chart speed. You can see the change on thescreen (both on the menu and on the chart record) as you press the keys.After you’ve made the adjustment, press the EXIT key to erase the menu.

CHART SPEED MENU CHART STOP MENU

To stop the chart, press the menu key, then press the up or down arrowkeys until the "CHART" menu appears as shown above right. Press theleft arrow key to stop the chart. To start the chart again, press the rightarrow key.

16

FISH IDThe Fish ID feature identifies targets that meet certain conditions as fish.The microcomputer analyses all echoes and eliminates surface clutter,thermoclines, and other signals that are undesirable. In most instances,remaining targets are fish. The Fish ID feature displays symbols on thescreen in place of the actual fish echoes. There are four fish symbol sizes:tiny, small, medium, and large. These are used to designate the relativesize between targets. In other words, it displays a small fish symbol whenit thinks a target is a small fish, a medium fish symbol on a larger target, etc.

The microcomputer is sophisticated, but it can be fooled. It can't distin-guish between fish and other suspended objects such as trotlines, turtles,submerged floats, air bubbles, etc. Individual tree limbs extending out-wards from a group of limbs is the hardest object for the Fish ID featureto distinguish from fish.

You may see Fish ID symbols on the screen when actually, there are nofish. Practice with the unit in both the Fish ID mode and without to becomemore familiar with the Fish ID feature.

When the X-65 is turned on, the FishID feature is automatically turned on,also. To turn the Fish ID feature off,press the menu key, then press thearrow keys until the FISH ID menuappears. Press the left arrow key toturn the fish ID feature off. To turn theFish ID feature on again, repeat theabove steps, but press the right arrowkey until the "ON" is highlighted. Anytargets the microcomputer determinesare fish will be displayed as fish sym-bols.

Remember, the Fish ID feature can’t be used when the X-65 is in themanual mode. If you turn the Fish ID feature on when the X-65 is inmanual, the microcomputer will turn the automatic feature on. If you turnautomatic off when the Fish ID feature is on, the Fish ID feature will beturned off also.

FISHTRACK™The FishTrack feature shows the depth of a fish symbol when it appearson the display. This lets you accurately gauge the depth of targets. Thisfeature is available only when the Fish ID feature is on.

17

When the X-65 is turned on, FishTrack is enabled. To turn the FishTrackfeature off, press the menu key, then press the up or down arrow keys untilthe FISH ID menu appears. Now press the left arrow key. Pressing it onceswitches the FishTrack feature off, but leaves Fish ID on. To turnFishTrack on, press the right arrow key, which highlights the "TRACK"label on the Fish ID menu.

CHART SETUPThe X-65 lets you customize the chartscreen. To do this, press the MENUkey, then press the up or down arrowkeys until the "CHART SETUP" menuappears. Now press the right arrowkey. The screen shown at right ap-pears.

The digital depth display at the top leftcorner of the screen normally showsin large numbers. You can change thisto smaller numbers or turn it off com-pletely using the "Show Digital" menuat the top of this screen.

You can also turn the temperature, speedometer, distance log, zoom bar,zone alarm bar, fastrak, and cursor on or off using this menu. See belowfor more information on these items.

FASTRAKThis feature converts all echoes toshort horizontal lines on the display’sfar right side. The graph continues tooperate normally. FASTRAK gives youa rapid update of conditions directlyunder the boat. This makes it usefulfor ice fishing, or when you’re fishingat anchor. Since the unit is not mov-ing, fish signals are long, drawn outlines on a normal chart display.FASTRAK converts the graph to avertical bar graph that, with practice,makes a useful addition to fishing at astationary location.

To turn FASTRAK on, highlight the "Show Fastrak" label on the "Chart

18

Setup" menu, then press the right arrow key. Press the EXIT key to erasethe menu. A screen similar to the one at the bottom of the previous pageappears. To turn Fastrak off, repeat theabove steps.

Groups FastrackSeveral windows groups have a Fas-track screen that looks a little differentthan the Fastrack used on the full screenchart. Windows Fastrack, shown onthe right side of this screen also con-verts echoes to short horizontal lines,but it also gives you scale lines to makeit easier to determine the depth of thetargets. You can use group "H" shownat right to help you learn how to use the Fastrack feature. Remember,Fastrack is only showing you the first column of echoes from the normaldisplay as they appear. It is simply converting each dot to a horizontal line.

CHART CURSORThe X-65 has a chart cursor that allows you to pinpoint a target’s depth.The cursor is simply a horizontal line that extends across the display fromleft to right. A depth box at the end ofthe line on the right side shows theline’s depth. In the example at right,the cursor (line) is at 41.1 feet.

To display the chart cursor, highlightthe "Show Cursor" on the "Chart Setup"menu, then press the right arrow key.A screen similar to the one at rightappears. Use the up and down arrowkeys to move the cursor up or down tothe desired depth.

To turn the chart cursor off, repeat theabove steps. The X-65 returns to the sonar screen without the chartcursor.

DISPLAY ZOOM BARWhen the unit is in the split-screen zoom mode, the zoom bar doesn’tnormally show on the screen. The zoom bar shows the section of wateron the right side of the screen that is being enlarged on the left side. Toturn the zoom bar on continuously when the split-screen mode is on,

19

highlight the "Show Zoom Bar" on the"Chart Setup" menu, then press theright arrow key. Now press the EXITkey. If you're not in the split-screenmode, change to that mode. A screensimilar to the one at right appears.

To turn the zoom bar off, repeat theabove steps.

DISPLAY ZONE BARThe zone alarm has a range bar. Anyechoes that appear between the topand bottom of this bar triggers thezone alarm. This bar normally doesn'tshow on the screen. To turn the zonebar on continuously, highlight the"Show Zone Bar" on the "Chart Setup"menu, then press the right arrow key.Now press the EXIT key. A screensimilar to the one at right appears. Toturn the zone bar off, repeat the abovesteps.

See the Alarms section in this manualfor more information on the zone alarm.

DIGITAL SONARWhen the X-65 is turned on, the digital depth display is located at the topleft corner of the screen. This display comes from a separate digital sonarbuilt into the unit. It displays only the bottom depth. If it loses the bottom,the last known depth will flash on the display. When the digital finds thebottom, it will automatically display the bottom depth again.

The digital sonar can be turned off, however this also turns all automaticfeatures off also, such as auto sensitivity, auto ranging, and the Fish ID.feature.

To turn the digital off, first press the MENU key, then press the up or downarrow keys until the "DIGITAL SONAR" menu appears. Press the leftarrow key to turn it off.

Note: Turning the digital sonar off also turns the automatic mode off,including Fish ID, and the depth alarms.

20

ALARMSThe X-65 has three different types of sonar alarms. The first is the FishAlarm. It sounds when the Fish I.D. feature determines an echo or groupof echoes is a fish. Another alarm is the Zone Alarm which consists of abar. Any echo that appears inside this bar triggers this alarm. The lastalarm is called the Depth Alarm. Only the bottom signal will trigger thisalarm. This is useful as an anchor watch, a shallow water alert, or fornavigation.

To adjust an alarm, first press theALARM key. The screen shown atright appears. Follow the instructionsbelow for setting each alarm.

DEPTH ALARMSThe depth alarms sound a tone whenthe bottom signal goes shallower thanthe shallow alarm’s setting or deeperthan the deep alarm’s setting. Forexample, if you set the shallow alarmto ten feet, the alarm will sound a toneif the bottom signal is less than tenfeet. It will continue to sound until the bottom goes deeper than 10 feet.The deep alarm works just the opposite. It sounds a warning tone if thebottom depth goes deeper than the alarm's setting. Both depth alarmswork only off the digital bottom depth signals. No other targets will tripthese alarms. If you turn the digital off, the depth alarms will be inoperative.These alarms can be used at the same time or individually.

To adjust the shallow alarm, highlightthe "Shallow Depth" label. To adjustthe deep alarm, highlight the "DeepDepth" label. Both alarms adjust iden-tically. We'll use the shallow alarm asan example. Highlight the "ShallowDepth" label, then press the right ar-row key. The screen shown at rightappears.

Use the up or down arrow keys toselect the number, the right and leftkeys to move from number to numberin the depth. For example, to set the shallow alarm depth to 10 feet, pressthe right arrow key once, then press the up arrow key once. The changes

21

the second "0" to a "1". Next, press theright arrow key again and press thedown arrow key once. This changesthe "1" at the end of the number to a"0". The depth now shows 10 feet.

Press the ENT key to accept thissetting. The X-65 returns to the alarmsmenu, showing a shallow depth of 10feet. Now you can activate the alarmby highlighting the "Shallow Alm" labeland pressing the right arrow key.

With the shallow alarm set at ten feet, anytime the digital display goesbelow ten feet, the shallow alarm sounds.

Set the deep alarm in the same manner. If the bottom depth reading goesbelow the deep alarm setting, the deep alarm will sound.

ZONE ALARMThe zone alarm is triggered when anyecho passes inside the zone alarmbar, shown on the right side of thescreen. To turn the zone alarm on,highlight the "Zone Alarm" label on thealarms menu, then press the rightarrow key. To adjust the zone alarm,highlight the "Zone Adjust" label, thenpress the right arrow key. A screensimilar to the one at right appears.

To adjust the top of the zone barhigher or lower, press the up or downarrow keys while the up and downarrows are surrounding the "Upper Zone" on the screen as shown above.To adjust the bottom of the zone bar, first press the right arrow key to movethe arrows to the "Lower Zone" on the screen, then use the up or downarrow keys.

When the zone alarm is set, press the EXIT key to erase the menus.

FISH ALARMUse the fish alarm for a distinctive audible alarm when fish or othersuspended objects are detected by the Fish I.D. feature. A different tone

22

sounds for each fish symbol size shown on the display. To turn the fishalarm on, press the ALARM key, then highlight the "Fish Alarm" label andpress the right arrow key. The unit will revert to the sonar display with thefish alarm turned on. Repeat the above steps to turn the fish alarm off.

Note: If the unit is in the manual mode, turning the Fish Alarm on will alsoturn the automatic mode and Fish ID on, also.

ADJUST CHART SURFACE CLARITYThe markings extending downward from the zero line on the chart arecalled “surface clutter.” These markings are caused by wave action, boatwakes, temperature inversion, and other natural causes.

The Surface Clarity Control (SCC)reduces or eliminates surface cluttersignals from the display. SCC variesthe sensitivity of the receiver, decreas-ing it near the surface and graduallyincreasing it as the depth increases.The maximum depth that SCC willaffect is 75% of the selected depthrange. For example, on a 0-60 footrange with maximum SCC, surfaceclutter will be reduced down to 45 feet.

There are three levels of SCC avail-able on the X-65: low, medium, and high. When it’s turned on for the firsttime, the SCC level is low. To change it, press the MENU key, then pressthe up or down arrow keys until the "Surface Clarity" menu appears. Nowuse the left or right arrow keys to change it. When you're finished, pressthe EXIT key to erase the SCC menu.

ASP (Advanced Signal Processing)The ASP feature is a noise rejection system built into the X-65 thatconstantly evaluates the effects of boat speed, water conditions, andinterference. This automatic feature gives you the best display possibleunder most conditions.

The ASP feature is an effective tool in combating noise. In sonar terms,noise is any undesired signal. It is caused by electrical and mechanicalsources such as bilge pumps, engine ignition systems and wiring, airbubbles passing over the face of the transducer, even vibration from theengine. In all cases, noise can produce unwanted marks on the display.

23

The ASP feature has two levels -Normal and High. If you have highnoise levels, try using the “High” ASPsetting. However, if you are havingtrouble with noise, we suggest thatyou take steps to find the interferencesource and fix it, rather than continu-ally using the unit with the high ASPsetting. However, there are times whenyou may want to turn the ASP featureoff. This allows you to view all incom-ing echoes before they are processedby the ASP feature.

To change the ASP level, press the MENU key then press the up or downarrow keys until the "ASP" menu appears. Now use the left or right arrowkeys to change it. When you're finished, press the EXIT key to erase theASP menu.

SYSTEM SETUPThe following features are availablethrough the "System Setup" menu. Toaccess this menu, press the MENUkey, then press the up or down arrowkeys until the "System Setup" menuappears. Press the right arrow key.The screen shown at right appears.

Audio/DisplayYou can adjust the display's contrastand turn the speaker off or on usingthis menu. To do this, highlight the"Audio/Display" label on the systemsetup menu, then press the right ar-row key. The screen at right appears.

To adjust the contrast, highlight the"Contrast" menu, then use the left orright arrow key to change it. Look atthe pattern at the bottom of this screento adjust the contrast for the bestsharpness.

To turn the speaker off, highlight the

24

"Speaker" label, then press the left arrow key to turn it off.

System InformationThis screen shows some basic data about the X-65. To view this, highlightthe "System Info" label on the System Setup menu, then press the rightarrow key. The system info screen appears. To erase this screen, pressthe EXIT key. The X-65 returns to the System Setup menu.

Units of MeasureThe X-65 normally shows the depth infeet, speed in statute miles per hour,distance in statute miles, and tem-perature in degrees Fahrenheit. Youcan change any of these settings us-ing the units of measure menu. To dothis, highlight the "Units of Measure"label on the System Setup menu, thenpress the right arrow key. The screenat right appears. Highlight the itemyou want to change, then press theright or left arrow key to change it. Toerase this screen, press the EXIT key.

Reset Distance LogIf you have a speed sensor attached to the X-65, the unit starts countingthe distance you've travelled each time you turn it on. You can reset thisdistance to zero by turning the unit off and on again, however, it's easierto highlight the "Reset Distance Log" label on the System Setup menu,then press the right arrow key. This resets the log and keeps you in theSystem Setup menu. To erase this menu, press the EXIT key.

Temperature GraphSome of the X-65's screens have a temperature graph, as shown at right.Normally, the temperature graph has a 2°range. On the screen shown at right, thetemperature graph has a range from 72° to74°. You can change this range to 4° or 10°using the "Temp Graph" label on the SystemSetup menu. Highlight that label, then pressthe right arrow key until the desired tempera-ture graph range is highlighted. Press theEXIT key to erase the menu.

25

SimulatorThe X-65 has a simulator built in that lets you use it as if you are on thewater. All features and functions of the unit are usable. A messageappears occasionally to remind you that the simulator is on.

To use the simulator, press the MENU key, then press the up or downarrow keys until the "System Setup" menu appears. When it does, pressthe right arrow key. Now press the up or down arrow keys until the"Simulator" label is highlighted. Finally, press the right arrow key. The X-65 returns to a sonar screen with simulated echoes scrolling across thescreen.

Preset OptionsThe X-65 "remembers" all settingssuch as units of measure, auto/manual, sensitivity, even when poweris removed from the unit. To return theX-65 to the factory settings, highlightthe "Preset Options" label on the "Sys-tem Setup" menu, then press the rightarrow key. The X-65 returns to the fullchart screen with all settings returnedto their factory values.

Keel OffsetThe X-65 measures water depth fromthe face of the transducer. Since thetransducer is below the surface of thewater, this distance is not the exactwater depth. If the transducer is onefoot below the surface, and the X-65reports the water depth as 30 feet,then the depth is actually 31 feet.

You can calibrate the depth readingusing the keel offset feature. First,highlight the "Keel Offset" label on the"System Setup" menu, then press theright arrow key. The screen shown atright appears. The current bottom depth shows in the upper left corner ofthe screen. The keel offset shows in the upper right corner. In thisexample, we need to change the keel offset so that the X-65 will add one

26

foot to the depth, since the transduceris one foot below the surface. Pressthe right arrow key, then the up ordown arrow keys until 1.0 appears inthe "Adj Keel" box, as shown at right,then press the ENT key. This immedi-ately changes the digital depth displayat the top of the screen by one foot.Press the EXIT key to erase this menu.

Note: Another way to use the keeloffset feature is if you want to knowthe depth of the water below the low-est part of the boat, instead of thesurface. To do this, measure the low-est part of the boat below the trans-ducer. In this example, we'll use 3feet. Now, using the keel offset fea-ture, adjust the offset for a negative 3feet, as shown at right.

Please note that adjusting the keeloffset only affects the digital depthdisplay and all features that use thedigital depth, such as the depth alarmsand FishTrack. This doesn't affect thechart at all.

Calibrate SpeedYou can calibrate the speed display ifan optional speed sensor is attachedto the X-65. To do this, highlight the"Calibrate Speed" label on the "Sys-tem Setup" menu, then press the rightarrow key. A screen similar to the oneat right appears.

If the digital speed display is slowerthan your actual speed, add a positivepercentage to make it read faster. Ifthe digital speed display is faster, use a negative percentage to make itread slower. Use the arrow keys to change the speed, then press the ENTkey. Press the EXIT key to erase this menu.

TROUBLESHOOTINGIf your unit is not working, or if you need technical help, please use thefollowing troubleshooting section before contacting the factory customerservice department. It may save you the trouble of returning your unit.

Unit won’t turn on:1. Check the power cable’s connection at the unit. Also check the wiring.

2. Make certain the power cable is wired properly. The red wire connectsto the positive battery terminal, black to negative or ground.

3. Check the fuse.

4. Measure the battery voltage at the unit’s power connector. It should beat least 11 volts. If it isn’t, the wiring to the unit is defective, the batteryterminals or wiring on the terminals are corroded, or the battery needscharging.

Unit freezes, locks up, or operates erratically:1. Electrical noise from the boat’s motor, trolling motor, or an accessorymay be interfering with the sonar unit. Rerouting the power and transducercables away from other electrical wiring on the boat may help. Route thesonar unit’s power cable directly to the battery instead of through a fuseblock or ignition switch

2. Inspect the transducer cable for breaks, cuts, or pinched wires.

3. Check both the transducer and power connectors. Make certain bothare securely plugged in to the unit.

Weak bottom echo, digital readings erratic, or no fish signals:1. Make certain transducer is pointing straight down. Clean the face of thetransducer. Oil, dirt, and fuel can cause a film to form on the transducer,reducing its effectiveness. If the transducer is mounted inside the hull, besure it is shooting through only one layer of fiberglass and that it is securelybonded to the hull. Do NOT use RTV silicone rubber adhesive orMarinetex

2. Electrical noise from the boat’s motor can interfere with the sonar. Thiscauses the sonar to automatically increase its Discrimination or noiserejection feature. This can cause the unit to eliminate weaker signals suchas fish or even structure from the display.

29

3. The water may be deeper than the sonar’s ability to find the bottom. Ifthe sonar can’t find the bottom signal while it’s in the automatic mode, thedigital will flash continuously. It may change the range to limits far greaterthan the water you are in. If this happens, place the unit in the manualmode, then change the range to a realistic one, (for example, 0-100 feet)and increase the sensitivity. As you move into shallower water, a bottomsignal should appear.

4. Check the battery voltage. If the voltage drops, the unit’s transmitterpower also drops, reducing its ability to find the bottom or targets.

Bottom echo disappears at high speeds or erratic digital reading orweak bottom echo while boat is moving1. The transducer may be in turbulent water. It must be mounted in asmooth flow of water in order for the sonar to work at all boat speeds. Airbubbles in the water disrupt the sonar signals, interfering with its ability tofind the bottom or other targets. The technical term for this is Cavitation.

2. Electrical noise from the boat’s motor can interfere with the sonar. Thiscauses the sonar to automatically increase its Discrimination or noiserejection feature. This can cause the unit to eliminate weaker signals suchas fish or even structure from the display. Try using resistor spark plugsor routing the sonar unit’s power and transducer cables away from otherelectrical wiring on the boat.

No fish arches when the Fish ID feature is off:1. Make certain transducer is pointing straight down. This is the mostcommon problem if a partial arch is displayed.

2. The sensitivity may not be high enough. In order for the unit to displaya fish arch, it has to be able to receive the fish’s echo from the time it entersthe cone until it leaves. If the sensitivity is not high enough, the unit showsthe fish only when it is in the center of the cone.

3. Use the Zoom feature. It is much easier to display fish arches whenzoomed in on a small range of water than a large one. For example, youwill have much better luck seeing fish arches with a 30 to 60 foot range thana 0 to 60 foot range. This enlarges the targets, allowing the display to showmuch more detail.

4. The boat must be moving at a slow trolling speed to see fish arches.If the boat is motionless, fish stay in the cone, showing on the screen asstraight horizontal lines.

30

NOISEA major cause of sonar problems is electrical noise. This usually appearson the sonar’s display as random patterns of dots or lines. In severe cases,it can completely cover the screen with black dots, or cause the unitoperate erratically, or not at all.

To eliminate or minimize the effects of electrical noise, first try todetermine the cause. With the boat at rest in the water, the first thing youshould do is turn all electrical equipment on the boat off. Make certain theengine is off, also. Turn your X-65 on, then turn off ASP (Advanced SignalProcessing). There should be a steady bottom signal on the display. Nowturn on each piece of electrical equipment on the boat and view the effecton the sonar’s display. For example, turn on the bilge pump and view thesonar display for noise. If no noise is present, turn the pump off, then turnon the VHF radio and transmit. Keep doing this until all electricalequipment has been turned on, their effect on the sonar display noted,then turned off.

If you find noise interference from an electrical instrument, trolling motor,pump, or radio, try to isolate the problem. You can usually reroute thesonar unit’s power cable and transducer cable away from the wiring thatis causing the interference. VHF radio antenna cables radiate noise whentransmitting, so be certain to keep the sonar’s wires away from it. You mayneed to route the sonar unit’s power cable directly to the battery to isolateit from other wiring on the boat.

If no noise displays on the sonar unit from electrical equipment, then makecertain everything except the sonar unit is turned off, then start the engine.Increase the RPM with the gearshift in neutral. If noise appears on thedisplay, the problem could be one of three things; spark plugs, alternator,or tachometer wiring. Try using resistor spark plugs, alternator filters, orrouting the sonar unit’s power cable away from engine wiring. Again,routing the power cable directly to the battery helps eliminate noiseproblems. Make certain to use the in-line fuse supplied with the unit whenwiring the power cable to the battery.

When no noise appears on the sonar unit after all of the above tests, thenthe noise source is probably cavitation. Many novices or persons withlimited experience make hasty sonar installations which function perfectlyin shallow water, or when the boat is at rest. In nearly all cases, the causeof the malfunction will be the location and/or angle of the transducer. Theface of the transducer must be placed in a location that has a smooth flowof water at all boat speeds. Read your transducer owner’s manual for thebest mounting position.
