PrefaceThe sophisticated, high-performance. Saab/Clarion audio system in your car features acompletely new design. It provides a higherlevel of operating convenience than everbefore in an automotive sound system.To make the most of the system's capa-bilities, however, you first will need tofamiliarize yourself with its features andcontrols. Please read this owner's manualcarefully before operating the receiver/tapedeck or equalizer/spectrum analyzer; then,practice performing the major tuning, cas-sette play and equalizer functions while thecar is stationary.You will be rewarded with optimum audioperformance and touchplate convenience onthe road.

Saab/Clarion AudioProtection SystemThe superlative performance and high-fidelity sound of your Saab/Clarion audiosystem were designed to give you manyyears oflistening pleasure. Unfortunately,these same qualities would make the systema tempting target for theft if protectivemeasures were not taken. These measureshave been taken with the Saab/Clarion AudioProtection System.

The Surest Protection:Removing Your RadioSince there is no foolproof way to prevent adetermined thief from breaking into yourcar, the most effective deterrent is to removethe incentive to do so: Nobody can takesomething that is not there to be stolen. Thatis why your Saab/Clarion AM/FM stereocassette/receiver has been designed on aremovable chassis.

Simply insert the special tools provided intothe holes on both sides of the cassette/re-ceiver faceplate until they lock in place.Withdraw the unit from the dash.

It takes just a few seconds and presentswould-be thieves with an empty space in-stead of a valuable target. You can eithertake the unit with you, or store it in yourtrunk. A specially designed protective carry-ing bag is available from your Saab dealer(Part Number 02 73 136).

This bag is a convenient place to store yourradio when it be removed and can also holdup to 8 cassettes and your Saab head clean-ing cassette (Part Number 0259994).

To reinstall your radio,just slide it back intoposition. Gently apply pressure between thetwo removal holes on each side of the unitsimultaneously until it locks into place.There are no wires to worry about andnothing for you to connect.

There is also a Tidy Box available (PartNumber 02 73 417) which can be insertedinto the radio bracket when the radio is re-moved. This box protects the radio connec-tions and at the same time offers a conve-nient storage space for small articles.The tidy box can be easily removed usingoutward finger pressure while pulling to-wards you.

W hen the radio is removed from the dash,it will retain any preset stations in mem-ory for at least one month. The equalizermemory will be retained as long as theunit is supplied with battery voltage.

Turbo cars come equipped with a thin blackcover that can be installed over the equalizerwhen the radio is removed. This will pre-vent the equalizer from being mistaken fora radio by would-be thieves when the radio/cassette unit has been taken out ofthe car.

Handling Precautions .1.Protect the unit from moisture, high

ambient temperature and humidity.Take sufficient care when cleaning theinterior of the car and provide adequateventilation,

2. Wipe the unit with a soft, dry cloth forcleaning. In cases of severe contamina-tion, use some cleaning alcohol. Neveruse benzine, solvents or the like.

U sing The Electronic Lock-OutSystem (S/TURBO)The second protective measure in the Saab/Clarion Audio Protection System is an ingen-ious electronic lock-out feature: This rendersthe cassette/receiver inoperable if it is re-moved from the dash or ifthe radio power isdisconnected during servicing or for anyother reason. The only way to make the unitfunctional again is by entering a special six-digit code, which only you know.

) 3313Keying in the code is simple. The easy-to-understand instructions are given on the spe-cial card which contains your code numbersand are repeated here. After you've put theunit back into the dash, simply:

1.Turn on the ignition.2. Depress Red Power switch once.3. Depress the Dynamic Noise Reduction

(DNR) switch, and keep it depressedthroughout the key-in procedure.

4. Key in your code numbers using thestation preset keys (1-6). After last digitis entered, release DNR switch and unitwill operate.

If you make a mistake when enter-ing your code, simply release the DNRswitch, depress it again. and enter thecorrect code.

The Saab/Clarion Audio Protection System isbuilt-in. To enjoy the years of listeningpleasure your audio system was designed toprovide, all you have to do is use it.

Code Entry Switches DNRSwitch

Owner Identification Card(S/TURBO)In your glove compartment, you will find anOwner Identification Card attached to acard carrier on which your electronic lock-out code and other important informationis recorded. Your card also contains thestep-by-step reinstallation proceduresoutlined above.When you have transferred the owner iden-tification information from your card carrierto your card, place the card in your wailet. Donot leave it in the glove compartment, whereit can fall prey to vandals. File the card car-rier with your other important documents,where it will not be available to anyone ex-cept you.If you look at your card, you'll see that yourRadio Part Number has already been record-ed on your Owner Identification Card. Besure to record your radio serial, electroniclock-out code, vehicle identification and theftI.D. numbers on your card before placing itin your wallet or other safe place. If you loseyour Owner Identification Card, contactyour Saab dealer.

Key Performance/Convenience FeaturesTouchplate ControlsTouchplate, electronically-activated controlsfor precision and convenience. Controls arelogically arranged and fall readily to hand,through ergonomically efficient design.Touchplate digital tuning eliminates conven-tional tuning knob inaccuracies.

Advanced FM CircuitDesignIncorporates an automatic distancellocalcircuit (Keyed Automatic Gain Control) thatautomatically adjusts FM tuner sensitivityfor ideal reception based on signal strength.Also, a dual-gate Field Effect Transistor/balanced mixer reduces interference fromstrong adjacent signals. A Signal ActuatedStereo Control (SASC) circuit reducesnoise and resists multipath interference,while a special noise-canceling circuitblocks strong noise impluses receivedthrough the antenna. It all adds up toclear, clean FM reception under virtuallyany operating conditions.

AM Stereo (S/TURBO)Compatible with all AM stereo broadcasts.As long as an AM station is broadcasting instereo, this tuner will receive the signal andreproduce it.

Cassette Head-Release SystemProtects tape and tape player from damageby automatically withdrawing the headfrom the tape when power is turned off.

Cassette Auto Reverse, AutomaticProgram SystemCassette will automatically reverse at the endof tape or can be manually reversed at anypoint during play. Automatic Program Sys-tem (APS) permits replay of current selectionor advancing on to the next.

Night IlluminationAll switches are fully illuminated for nightviewing.

Automatic Antenna CircuitWhen the radio is turned on, the electronicantenna automatically extends. When theradio is turned off, the antenna automatic-ally retracts.

When entering an automatic car wash, besure to turn the radio off. If the car isdriven through the car wash with theantenna extended, the antenna might bedamaged.

AM/FM Features andOperationPower SwitchPress Red Power switch to turn the radioon. To turn radio off, press the Powerswitch again. If you hear a warning beep,you must enter your six-digit electroniclock-out code. (See Saab/Clarion Protec-tion System, p. 3.)

Audio ModeThe Audio Mode Selection switch is locatedto the left of the cassette door. The primaryaudio mode is volume. In addition toregulating volume, these controls permitfader, balance, bass and treble adjustmentsas described below.

Volume ControlDepress the + switch to increase volume orthe - switch to decrease it. The red volume(VOL)indicator will illuminate. The lights onthe audio mode indicator graph will illum-inate left to right as volume increases andright to left as volume decreases. If thevolume is at an excessive level when theradio is turned off, it will automaticallybe reduced by 30% when the radio is turnedon again.

Fader(Front to Rear) Depress the Audio Mode Selec-tion switch once.The dark green fader (FAD)indicator will illuminate, and the central

point in the audio mode indicator graph willglow red. Use the +/- switches to increase ordecrease the proportion of sound from thefront or rear speakers. When the red pointalone is lit, the sound is centrally balanced.

Balance(Left to Right) Depress the Audio Mode Selec-tion switch twice. The yellow balance (BAL)indicator will illuminate, and the centralpoint in the audio mode indicator graph willglow red. Use the + / - switches to increase ordecrease the proportion of sound from theleft or right speakers. When the red pointalone is lit, the sound is centrally balanced.

BassDepress the Audio Mode Selection switchthree times. The amber bass (BASS)indicatorwill illuminate, and the central point in theaudio mode indicator graph will glow red.Use the +/ - switches to increase or decreasethe bass (low frequencies). When the redpoint alone is lit, the bass is at its normal (flat)frequency setting.

TrebleDepress the Audio Mode Selection switchfour times. The light green treble (TREB)in-dicator will illuminate, and the central bar inthe audio mode indicator graph will glowred. Use the +/- switches to increase ordecrease the treble (high frequencies). Whenthe red point alone is lit, the treble is at itsnormal (flat) frequency setting.

IMPORTANT:When using the seven-band graphicequalizer, the bass and treble settingsshould be left in the center position.Verify the settings by selecting thosemodes and making sure only the redcentral point in the audio mode indica-tor graph is illuminated.

The audio mode selector will automati-cally return to volume from any mode ifit is left alone for more than five seconds.

Tuning ModeUse the Tuning Mode switch to select manualor seek tuning. The frequency display willindicate which mode you are in.Manual tuning is accomplished by pressingthe < < or > > switches. The < < switchlowers the frequency. The> > switch raisesthe frequency.In the Seek Tuning mode, the radioautomatically seeks out the next clear stationwhen the < < or > > switch is depressed.Use the < < switch to seek the next clearlower frequency station, the> > switch toseek the next clear higher station.

Station PresetsYou can preset up to 18 stations-six on eachofthe three indicated bands. Once you knowwhich stations you'll enjoy listening toregularly, you can use the preset function tosummon them instantly.

First, use the BAND switchto select the AM,FM lor FM 2 band. Note that FM 1 and FM 2both represent the regular FM band. Theduplicate listing merely allows you to storesix FMstations on one band, and six differentFM stations on the other.Using the manual mode, select the first sta-tion to be preset. Generally, this will eitherbe the station you listen to most often or thefirst station on the dial that you listen to fre-quently. Use whatever sequence is easy foryou to remember. To enter this station inmemory, depress and hold the No. 1memory preset switch. Ch(annel) 1 will il-luminate on the tuning display. While thisswitch is held, you will hear the volumedecrease and then return to its original level.When it returns to its original level, releasethe switch and that station is memorized.Tune to the next station you want memor-ized and repeat procedure on next channelswitch. To call up a memorized station,simply tap the appropriately numberedmemory preset.

Auto StoreIf you are driving in an unfamiliar area-andthereby lose the stations you generally listento-you can use the auto store function to findand memorize the strongest stations in thearea in which you're driving. To activate theauto store function, depress the AutoStore/Preset Scan (SCAN/STORE) switchfor two seconds. In this mode the radio will

automatically scan the entire frequencyband (AM if on AM, FM if on FM). Sixstations with strong signal strength will bestored in the radio's memory. If six strongstations cannot be found, weaker stationswill be chosen. The auto store function willonly store six stations at one time-six onAM or six on FM.

If you use the auto store function, you willlose the stations that had previously beenprogrammed into memory. They can bereset when you are again driving in yourlocal area.

Preset ScanIn the preset scan mode, the radio will auto-matically scan the stations stored in itsmemory (six ifon AM band, and twelve if onFM band). Activate the preset scan mode bydepressing the SCAN/STORE switch forless than two seconds. Once the desiredstation is reached, stop the scanning pro-cess by pressing the SCAN/STORE switchagain. The radio will not automaticallyswitch from AM to FM while in the presetmode.

Stereo IndicatorWhenever the radio is receiving a stereosignal, whether AM or FM, the stereo (ST)indicator will illuminate in the right centerof the frequency display.

Band WidthThis BW switch will increase the band widthon AM stations broadcasting in stereo if thesignal you are receiving is weak. Whenthe BW mode is activated, a BW will appearin the upper right-hand corner of thefrequency display.

Dynamic Noise ReductionThe Dynamic Noise Reduction (DNR)switchcan be used to limit background noise onboth AM and FM bands. When the DNRswitch is activated, DNR will illuminatein the lower right-hand corner of thefrequency display.

Cassette OperationTo startDepress the Power switch to activate theunit, and the radio will begin playing. If youhear a warning beep, enter your six-digitcode. Insert a cassette-desired playing sideup and the exposed-tape side ofthe cassetteto the right. The tape will begin playing, andthe appropriate tape direction indicator willlight. ( = reverse.)Next, adjust volume with the +/- audiomode control switches. Select the appro-priate tape equalization and noise reductionsetting (described later in this section.)

Cassette ProgrammingThe tape player features auto reverse, whichmeans the second side of a cassette willautomatically be played when the first sideis finished. But, if you decide you'd like tolisten to Side Bmidway through Side A, youcan switch instantly simply by pressing theTape Program switch.

Fast Forward or RewindFast forward or rewind is accomplished bypressing the < < or > > switch. It is notnecessary t.ohold the switch while the tapeIS forwarding or rewinding. The tape willwind at high speed in the direction thearr-ows are pointed. The appropriateindicator will illuminate above the arrowCheck tape direction indicator before press~mg FF or REW to verify tape direction.

NOTE:- To release the cassette from fast for-

ward, press the Fast Forward switchagain. To stop the cassette from re-win?ing, press the Rewind switchagam.

- If tape is wound completely in the FFmode, it will stop automatically andplay the opposite side. If tape is woundcompletely in the REW mode, it willstop automatically and play the sameside.

- If the tapeis in the FF or REW modeand th~ Program switch is pressed, thetape will stop and begin play in theopposite direction.

Automatic Program System (APS)This feature provides still more flexibility. Itallows you to repeat the selection you're cur-rently listening to or jump ahead to the nextselection before the current one is finished.

, :0 repeat the selection that is currently play-mg, tap the APS switch (an APS indicator willlight) and the cassette rewind or fast-forwardcontrol-w hichever direction is opposite thatof current tape travel as shown by the tapedirection indicators.To jump to the next selection, tap APSand the cassette rewind or fast-forward con-trol corresponding to the current direction oftape travel.

NOTE: The APS system may occa-sionally be "fooled" by the long low- Ilevel passages in classical music, sincethese resemble the silent gaps betweenselections. '

Tape EqualizationThere are several different types oftape cur-rently in use, and a Tape Equalization switch(~arked MTL for metal, a tape type) is pro-vided to enable you to match their playbackcharacteristics for the best sound. Most tapeshave a normal equalization of 120l-'s (normalbias), Unless there is some iridication to thecontrary-such as the designations "metal,""chrome" or "70I-'S" (high biasl=you canassume that the tape requires normalequalization and no adjustment is necessary.However, high-performance metal andchrome cassettes (as well as ferrichrome aninfrequently used tape type) require a dif-ferent equalization. You can provide it bypressing the MTL switch. The MTL indicatorwill light to confirm proper equalization.There is one important exception: Manypre:ecorded cassettes today use chrome tapefor Improved performance with normal bias(120l-'s) equalization. When playing suchcassettes, do not use the Tape Equalizationswitch.

Noise ReductionThis tape player offers two types, Dolby®"B" and Dynamic Noise Reduction (DNR). Ifa cassette is Dolby encoded (look for the DD ),press the Dolby DD switch. If the cassette isnot Dolby encoded, the DNR switch will stillprovide useful noise reduction. There are il-luminated indicators for both controls.

Tape PauseThe Tape Pause (.) switch enables you to in-terrupt cassette play temporarily andresume exactly where you left off. If the tapeis in either FF, REW or play mode and thePause switch is pressed, the tape will stop. Toresume play, depress the Pause switch again.Normal play will begin even if the cassettehad been in the FF or REW mode.The radio cannot be played when the pausemode is engaged.

Head-Release SystemIf the power is turned off while the tape isplaying or the pause mode is engaged,the tape head will automatically release.When the power is turned on or the Pauseswitch is pressed again, the tape will beginnormal play.

~ectWhen you're finished listening to a tape,simply press the Tape Eject ( • ) switch. Thecassette will be released for retrieval fromthe tape slot, and the radio will resumeplaying the most recently tuned station. Toeject a cassette after the power has beenturned off, depress the Eject switch andhold for more than two seconds.

Routine MaintenanceTo perform at its peak, your tape player re-quires periodic cleaning and demagnetiza-tion (elimination of the magnetic field thatgradually builds up around the playbackhead). Ofthe two tasks, cleaning is the mostimportant-dulled high frequencies willresult ifit is not carried out, regularly.Cleaning should be performed after everyeight to ten hours of playing time, using theSaab head-cleaning cassette (Part Number 0259 994) or that of another reputable brand.Demagnetizing should be carried out every!50to 100hours of playing time, using a quali-ty head demagnetizer (available from mostcar stereo and audio stores).

HANDLING TIPS:-Store cassettes in their plastic cases

when not in use.-Do not leave cassettes in your car, par-

ticularly during warm weather.- Take up any slack in the cassette before

playing.

-Do not play C-120 (or longer) cassettes.The tape in these cassettes is very thinand prone to breakage.

JComputer ControlEqualizer/SpectrumAnalyzer OperationThis sophisticated graphic equalizer/spectrum analyzer provides a range oftonaladjustments far beyond the capabilities ofconventional tone controls. Because alteringfrequency response for better sound re-quires that you pay very close attention towhat you are hearing, it is stronglyrecom-mended that the equalizer be 'operated onlywhen the car is stationary.Similarly, because the spectrum analyzerenables you to see the frequency band com-ponents and sound levels ofthe music youare listening to, it would prove distracting onthe road and should not be used while driving.However, you can easily and safely summonup any of three preferred frequency bandequalizer settings simply by tapping on theprogrammed memory preset switches.

NOTE: If the Defeat (DE) switch hasbeen pressed and the DE indicator ison, the equalizer will be inoperative un-til DE is pressed again to override it.The Defeat switch serves as the on-offcontrol for the equalizer.

Equalizer MemoryThis unit's equalizer is capable of storing upto three separate settings in its memory. Usethe frequency band activators and controlswitches to make your equalizer ad-justments. As an example, suppose you wantto decrease the treble content ofthe music (at10 k.Hz) to reduce tape hiss. Press the 10Kactivator, and the yellow indicator lightat the center of that frequency band willflash on and off for approximately 10seconds to indicate that your command hasbeen received.

.While the indicator is flashing, deempha-size this frequency by depressing andholding the - frequency band controlswitch.Release the - frequency band control switchwhen you think you've reduced thisfrequency far enough. Conversely, toemphasize the selected frequency band,depress the + frequency band controlswitch.'Repeat this procedure with each frequencyband that needs adjusting. Then, if you wishto enter your settings in memory, simplypress the Memory (ME) switch and the ap-propriate frequency band memory presetwithin five seconds.

60 Hz Frequency BandControls the extreme low frequencies.Can be used to counter the masking effect ofroad noise, etc.

125 Hz Frequency Band .Controls the low frequencies.Boosting this frequency range emphasizesthe sound of bass drums, etc. Cutting thisfrequency range can help to alleviatemuffled speaker sound.

250 Hz Frequency BandControls the medium-low frequencies.Rhythm section instruments (drums, bass,etc.) are centered around this frequencyrange.

500 Hz Frequency BandControls the lower mid-range frequencies.The main sound energy of most instrumentsand human voices is centered around thisfrequency range.

1 kHz Frequency BandControls the mid-range frequencies (above500 Hz).

13

3 kHZ Frequency BandControls the upper mid-range frequencies.The human ear is most sensitive in thisrange. Excessive boost can therefore lend astringent quality to the sound.

10 kHz Frequency BandControls the high frequencies. Can be used toattenuate tape hiss, etc. .

NOTE: There is a permanent memorysetting encoded into the equalizer. Ifthe battery power is disconnected forany reason, the equalizer memory willreturn to these three settings:

Preset switcho+ 12 dB (maximum)UOdB(flat)U -12 dB (minimum)

Any settings you wish to program into thememory will override these permanent set-tings as long as battery power is supplied tothe unit.

Spectrum AnalyzerSimply press the Equalizer/Spectrum Anal-yzer (EQ) switch to turn on the spectrumanalyzer; the EQ indicator will go out. Usethe spectrum analyzer display to confirm'the evidence of your ears. For example, if youfeel the music could use more deep bass,and the spectrum analyzer confirms thatthere is little or no musical energy in thelower frequency bands, then adjust theequalizer accordingly.

Low Level SwitchDuring high-powered listening, use of theLow Level (LO) switch will ensure that themusical content displayed does not exceedthe upper level of the spectrum analyzer.

Defeat SwitchTo restore flat (0 dB) frequency response,

. press the Defeat switch. The DE indicatorwill light, and all seven frequency band 0 dB

indicators will flash to indicate reception ofthe command. As long as the DE indicator isilluminated, the frequency band activatorsand the equalizer itself are inoperative. Toreadjust frequencies and turn on theequalizer again, you must first re-press theDefeat switch to release it.

Display SwitchIfthe spectrum analyzer is distracting, it canbe turned off by depressing the Displayswitch. This will not affect the performanceof the equalizer; it will simply make thedisplay invisible.

If the unit is in the spectrum analyzermode when the power is turned off,the equalizer settings will be displayedwhen power is resumed. In ten seconds,the spectrum analyzer display willappear again.

Broadcast ReceptionPerformanceCharacteristicsFM reception poses particularly challengingproblems because FM radio waves are trans-mitted at very high frequencies in straightlines like light waves. Any number of obsta-cles can and do get in the way: tall buildings,hills, etc. Such obstacles can cause "shad-ows" with momentary loss of signal.In addition, FM signals can also -be reflectedby obstructions. When this happens, directand reflected signals from the same stationcan arrive at the car's antenna simultane-ously. The noise this causes is known as mul-tipath interference.

The tuner in this unit was designed to mini-mize multipath interference and othercommon reception problems.Under weak signal conditions, the Signal Ac-tuated Stereo Control (SASC) circuit takesover to provide the strongest possible signal,switching to mono reception when circum-stances warrant. An automatic distancellocalreception circuit (Keyed Automatic GainControl) provides full sensitivity, while adual-gate FET RF amplifier provides a highsignal-to-noise ratio.Optimum selectivity virtually eliminates in-terference from strong nearby stations, anda special FM noise canceller works to sup-

press ignition noise and other pulse interfer-ence. Wide dynamic range avoids overloaddistortion and the unpleasant noise it causes.Nor has AM reception been neglected in thedesign of this tuner. A special circuit featurepermits only the strongest, clearest stationsto get through when broadcast conditionsare less than optimum. It is one more refine-ment that accounts for the superb perfor-mance of the tuner and adds to your listen-ing enjoyment.

AMandFMBoth AM and FM reception have advantagesand disadvantages resulting from their dif-fering properties. AM waves can reachlonger distances than FM waves. They canbend around buildings or mountains andbounce off the ionosphere. This means thatan AM service area is very wide.FM waves, on the other hand, have muchhigher frequencies and shorter wavelengths. Unlike AM waves, they cannot travelaround corners. They reflect off solid ob-jects in their path, which limit the areas theycan reach. An average FM signal can beheard only within a 25-mile to 35-mile radiusof a transmitter.

Stereo and MonauralStereo and monaural FM reception charac-teristics are also different. Monaural trans-mission utilizes the range of audio frequen-cies audible to the human ear. Stereotransmission relies on a range of frequenciesthat extend beyond human hearing limits onboth the high and low ends. This broadenedfrequency range requires more power,thereby reducing the range of a stationbroadcasting in stereo.
