Primary Battery Installation

• WARNING – – Lithium batteries can explode– Reverse polarity can cause damage to the battery

and receiver• CAUTIONCAUTION –

– Battery Types– Do not mix battery type– DAGR Used for 1st Time– DAGR Resets to Default

• Note– No Battery Charge

24


a. Ensure power to the DAGR is off.

b. Hold unit firmly upside down with the battery pack facing up.

c. Push or pull latch located on the battery pack to release battery pack.

d. Lift up on battery pack and remove from unit.

25


e. If batteries are already installed, pull out on the battery removal strap to remove batteries from the battery pack. Dispose of batteries properly

f. Position the battery removal strap into the channel of the battery pack before installing new batteries.

g. Install new batteries and ensure correct polarity installation for each battery (marked on battery pack).

h. Prior to installing the battery pack, inspect the battery pack gasket for damage or dirt. Lubricate or replace gasket if necessary. Ensure battery removal strap is not protruding from the battery pack.

26


i. To install new battery pack, position tab on battery pack in slot on the DAGR.

j. Close battery pack against DAGR until battery pack is engaged.

27

Memory Battery Installation

• Warning– Lithium batteries can explode– Reverse polarity can cause damage to the

battery and receiver

• CautionCaution– DAGR Used for Time– DAGR Resets to Default

• Note– Battery Types

28


a. Ensure power to the DAGR is off.

b. Place unit upside down on non-abrasive surface with the memory battery cover facing up.

c. Use flat blade screw driver to loosen three captive screws securing memory battery cover, then remove cover from unit.

d. Remove the memory battery and properly dispose of battery.

29


e. Prior to installing the memory battery cover, inspect the memory battery cover gasket for damage or dirt. Lubricate or replace gasket if necessary.

f. Install the memory battery.

g. Install memory battery cover and tighten three screws.

30

Powering on the DAGR

a. Push the (PWR/QUIT) key to turn the DAGR on.

b. The power-on status message shows for two

seconds, then time out if the following are true.

• Self-test has passed

• DAGR does not need initialization

If not, push the (WP/ENTER) key to acknowledge.

31

Powering on the DAGRc. If a CV key, GUV key, or SV code condition exists, acknowledge messages accordingly.d. DAGR displays the SV Sky View page, then automatically switches to the Present Position page when current position is acquired.

e. If keypad/display lighting is required, toggle lighting on and off by pushing and holding the (Bright/Menu) key.f. Adjust keypad/display brightness level by simultaneously pushing and holding the (Bright/Menu) key and using the (up and down arrow) keys

32

Mode of Operation

• Continuous - Tracks satellites to produce a continuous PVT solution, and uses the most power.• Fix - Tracks satellites to produce a current PVT solution, then automatically transitions to Standby mode after a position fix is obtained.• Standby - Operates at reduced power and does not acquire and track satellites, but performs all functions that do not require satellites.• Other available modes - Average, Time Only, Rehearsal, Test, and Off.

Receiver Setup(MANUAL INITIALIZATION)

If the DAGR has been moved between two different geographical locations and is not performing correctly, the DAGR may need to be initialized according to the DAGRs current location. The following procedure describes how to initially set up the DAGR Present Position page fields and edit field content when:

• DAGR is having difficulty obtaining a position fix.

• Datum is mismatched with navigation waypoints.

• Datum does not match the geographical map used.

Receiver Setup(Manual initialization)

46

Acquire Current Position The DAGR obtains current position by simply turning the

DAGR on with an open view of the sky. While acquiring satellites, DAGR displays the SV Sky View page. After satellites are acquired, DAGR automatically transitions to the Present Position page with current position coordinates shown. An indication of when the DAGR has obtained current position is provided by:

– Position data fields of the Present Position page remain solid black text and

do not blink.– On the SV Sky View page, solid black horizontal bars indicate satellites being

tracked and data is collected; and Navigating shows at the top of the display.

47

Acquire Current Position

The POS page set contains commonly used pages and are described in the upcoming slides:

1. Use the key or key to scroll pages.

WAYPOINTS

• A Waypoint is position information used to navigate through terrain, define routes or navigation alerts, mark present or remote positions, or marking observation points and landmarks.

NAVIGATION(Operation)

• Current position is necessary before accurate navigation can be accomplished.

The GOTO WP function uses the DIRECT TO navigation method. Navigation information to the selected destination waypoint is automatically displayed using the NAV Pointer page.

Waypoint Alerts

Definition: Alerts are made up of one or more waypoints, and are used to notify the operator is approaching or leaving a point, line, or area of significance (e.g., radius distance from a waypoint, defining a line not to be crossed, mine field area).

65

Waypoint Alerts(Continued)

• Anchor – Circular area defined by a radius from a waypoint. Activates when outside a defined radius.

• Hazard – Circular area defined by a radius from a waypoint. Activates when inside a defined radius.

• Buffer Zone – Rectangular area defined by two waypoints. Prevents the user from entering a defined area.

66


• Corridor – Rectangular area defined by two waypoints. Prevents the user from exiting a defined area.

• Other alerts include – Area, Boundary Line/ Phase Line, Position Error, and Time/Date.

DATA CLEAR

• Data Clear can destroy mission critical data.

CONCLUSION

The DAGR is a great tool for navigation, but it takes training to ensure continued

proficiency in the use of the device and still requires each soldier to understand

military map and land navigation techniques.
