MANPACK

To assemble a manpack radio, you must first check and install the battery.

Lithium battery for the manpack radio

The lithium battery used with your manpack radio is hazardous if misused or tampered with before, during or after discharde. Strictly observe the following precauthions to prevent injury to personnel or damage to equipment.

Do not heat, incinerate, crush, puncture, disassemble, or otherwise mutilate battery, short circuit, recharge, or bypass any internal fuse and do not store battery in equipment during periods of non-use.

When would your turn off equpment?

if you feel battery case becoming very hot, hear battery venting (hissing or burping), or smell irritating gas (sulphur dioxide).

Installation of primary batter and batter box to RT

• visually inspect battery box for dirt and damage
• stand RT on front panel guards; place battery box on RT. Secure using latches.
• check battery life condition (written on battery if battery is not new)
• write down number (for later entry into radio)
• place battery in battery box and mate connectors.
• close battery box cover, and secure using latches.
• return radio to upright position.  

Entering battery life condition into the radio

Set FCTN to LD

Press BATT; then CLR

Enter number recorded on side of battery

Press STO

Set FCTN to SQ ON

Antenna

Do not use antenna as a haddle. Equipment damage may result. Keep antenna straight up if possible.

• screw whip into antenna base (hand tighten)
• carefully mate antenna base with RT ANT connector
• hand tighten (important not to over-tighten)
• position antenna as needed by bending gooseneck 

Handset

Field Pack

Place RT in filed pack with antenna on the left. Fold top flap of field pack over RT and secure flap to field pack using straps and buckles.

Vehicle Radio Component

vehicular radios are installed and removed by maintenance personnel.

High voltage exists at connector J1 on mounting adapter. Avoid injury: be sure J1 is covered or capped when not in use.

what are the four methods to tie down an antenna?

Stay-down clamp

Snap-free clamp

Loading SC Frequencies

• Obtain authorized operating frequency from SOI or NCS
• Set FCTN to LD
• Set MODE to SC
• Set CHAN to MAN, CUE, or desired channel (1-6) where frequency is to be stored
• Press FREQ (display will show "00000", or to frequency RT is currently tuned.)
• Press CLR (display will show five lines)  
• Enter the number of the new frequency (using keyboard buttons)
• Press STO
• Repeat the eight steps above for additional frequency you wish to load
• Set FCTN to SQ ON

Inspect the equipment

check all major components for damage and serviceability

• receiver-transmitter
• battery box
• antennas and support bases
• harness and accessory bag
• headset or handset 

Clean the equipment

• Inspect the exterior of the radio set
• clean the external surface by removing dust, dirt, grease, salt, and fungus
• remove all dust and loose dirt with a clean rag and a general-purpose brush
• clean the audio connector pins ont he radio and handset with a rubber eraser

Preform operation checks

• conduct inventory
• check the accessories for cleanliness and serviceablity using FITCAL
• report any discrepancies
