Note: If the compensation result value exceeds 18

MILS, repeat the AVAM 12 STEP COMP before

proceeding. If the compensation result exceeds 180

MILS, select RESET TO DEFAULTS prior to

repeating STEP 1 of the AVAM 12 STEP COMP.

12-STEP AVAM COMPENSATION SEQUENCE

22. Rotate the IMAGER SELECT switch to the THERMAL position. The

thermal imager will again completely cool down. WAIT UNTIL THE

COOLER MOTOR AUDIBLY THROTTLES BACK. WAIT 30 ~ 60 SEC.

BEFORE PROCEEDING.

23. Select AVAM 4 STEP COMP. For STEP 1, point the TLM NORTH

(between 6300 and 0100 MILS) and tilt the TLM up (between 0350 and 0550

MILS) using the AZIM and ELEV readings from the display.

24. Move the cursor to COMPENSATE COMMAND and press the ACTION

key for each compensation step. Perform the remaining 3 STEPS using the

AZIM and ELEV readings from the display. Rotate the TLM clockwise and

tilt it accordingly as shown in the 4-STEP AVAM COMPENSATION

SEQUENCE figure. The calculated compensation result will be displayed atthe end of the 4 STEP COMP.

25. Note compensation result value, then EXIT, and then QUIT twice.

Note: If the compensation result value exceeds 18

MILS, repeat the AVAM 4 STEP COMP before

proceeding. If the compensation result exceeds 180

MILS, select RESET TO DEFAULTS prior to

repeating STEP 1 of the AVAM 4 STEP COMP.

Note: Remove the TLM Lens Covers and stow them between TLM and LDM

prior to adjusting the display settings.

26. Select SETUP, DISPLAY. Select RETICLE or BRIGHTNESS and adjust

as needed to accommodate scene and ambient light levels. Select QUIT.

27. Select SYSTEM INFO and select SAVE SETTINGS. Ensure SystemParameters Saved message appears on the screen window, then EXIT, and

then QUIT.

28. Verify that the GPS has acquired and is displaying SENSOR LOCATION

with a GPS ERROR < 25 M.

29. The TLM is now ready for Target Location using either the thermal camera

(IMAGER SELECT in THERMAL) or the day camera (IMAGER SELECT

in STANDBY). Select IMAGER to access appropriate controls for the

chosen camera.

30. If the thermal image exhibits excessive shading or washout, select:

IMAGER, TISA SETUP. Select NORMAL for AMBIENT TEMP. Select

INTERNAL NUC (the NUC process takes about 30 seconds). Wait for

message TISA Internal NUC Complete. Perform EXTERNAL NUC by

selecting EXTERNAL NUC (the NUC process takes about 30 seconds).

Wait for message TISA External NUC Complete, then EXIT, and then

QUIT.

Note: Install the TLM Lens Covers when performing External NUC.

31. The thermal image can be selected to display the target as white-hot or

black-hot. With the IMAGER SELECT in THERMAL, select IMAGER,

TISA POLARITY. The display will toggle between Blk for black-hot and

Wht to white-hot.

Note: The operator should use an ambient temperature rangesetting that will allow detection and identification with the thermal

imager without the scene being washed out. NORMAL is used

for most operational ambient temperatures. The most sensitive

setting is ARCTIC, which should not be used when ambient

temperature is higher than 41F (5C). DESERT must be used

when ambient temperature is above 104F (40C). AGC must be

initially on when temperature range is switched to prevent a scene

washout. Manual operation of TISA contrast and brightness may

then be performed. It may be necessary to re-perform NUC aftertemperature range switching.

32. Select DEFAULT RANGE (the default minimum range of 100 meters will

appear above it). For targets at much longer ranges or with foreground

clutter, select MINIMUM RANGE instead and adjust to the estimated

minimum target distance (the current minimum range gate value will appear),

then press ACTION key.

33. Select FIRST/LAST and toggle to select the desired target logic.

34. Fire the Laser Rangefinder by pressing and holding the FIRE pushbutton for

about one second (an audible tick is heard when the ELRF fires). Target

azimuth (AZ), slant range (RNG), and vertical angle (ELA) will be

displayed. When the button is released, the target grid position will be

calculated and displayed. Target data is displayed for 30 seconds. A quick

press of the FIRE button will redisplay the last data.

Note: If the displayed horizontal range to the target is more than 10 kilometers,target range data might not be accurate and shall not be considered valid during

training or normal operation.

The Laser Designator Module (LDM) Laser/Optical Assembly

contains two, 4-microcurie radioactive Americium-241 (Am241)

sealed source assemblies. These assemblies are potentially

dangerous, if broken. Do not open or perform any maintenance on

the LDM Laser/Optical Assembly. If the LDM case is broken or

cracked, notify your Radiation Protection Officer (RPO). Wrap

the LDM in a plastic bag, and store in a safe location until the RPOcan perform an evaluation. Follow safety procedures for storage,

shipment, and disposal in accordance with this manual AR 385-11

and FMFM11-17.

Prior to shipping the LDM using a commercial carrier, the packaged unitmust be certified to be free of external radiation. Once the LDM has

been packaged for shipping, the local transportation office must perform

a wipe test of the packaging surface, and have the results certified to be

radiation-free before authorization can be given to ship the LDM.Contact your RPO and local transportation office for specific

instructions.

The LDM must be stored in rooms/areas/sections designated for storageof radioactive materials, which are free from the danger of flooding,

outside the danger radius of flammables or explosives and secured

against unauthorized entry.

Post the area with CAUTION-Radioactive Material signs as required byAR 385-30.

DANGER

INVISIBLE LASER RADIATION

AVOID DIRECT EXPOSURE TO THE BEAM

The Laser Designator Module (LDM) is NOT eyesafe! The LDMutilizes a Class IV laser, which presents a severe laser eye/skin

hazard for extended distances. When using the LDM, ensure that

personnel adhere to the following precautions, in order to avoid

serious injury:

Do not stare into the laser beam. Do not look into the laser beam through binoculars or telescopes. Do not point the laser beam at mirror-like surfaces. Do not point the laser beam at individuals. Inspect the LDM Energy Test Cover for cracks, defects and foreign

matter prior to test firing the LDM Laser Designator. If cracked or

defective, DO NOT fire the LDM into the Energy Test Cover. This

could present a severe eye/skin hazard to personnel. If dirt or other

foreign matter is visible, clean the Energy Test Cover before installing to

the LDM.
