SAFETY STEPSDO NOT TRY TO PULL OR GRAB THE INDIVIDUAL.

IF YOU CANNOT TURN OFF THE ELECTRICAL POWER,PULL, PUSH, OR LIFT THE PERSON TO SAFETY USINGA DRY WOODEN POLE OR A DRY ROPE OR SOME OTH-ER INSULATING MATERIAL.

SEND FOR HELP AS SOON AS POSSIBLE.

AFTER THE INJURED PERSON IS FREE OF CONTACT

WITH THE SOURCE OF ELECTRICAL SHOCK, MOVETHE PERSON A SHORT DISTANCE AWAY AND lMMEDl-ATELY START ARTIFICIAL RESUSCITATION.

FOR ARTIFICIAL RESPIRATION, REFER TO FM21-11.

WARNINGRF ENERGY IS PRESENT NEAR ANTENNA DURING TRANS-MISSION MAINTAIN AT LEAST 30 INCHES BETWEEN VEH-ICULAR ANTENNA AND PERSONNEL DURING TRANSMIS-SIONS . WARNING

HIGH VOLTAGEEXISTS AT CONNECTOR J1 ON VEHICULAR MOUNTINGADAPTER. AVOID PERSONAL INJURY: BE SURE J1 IS COV-ERED OR CAPPED WHEN NOT IN USE.

DEATH OR SERIOUS INJURY CAN RESULT:q When antenna tip caps are not installed on antennas.q When a tied-down antenna hits a fixed object such as an

overhead bridge, tree Iimb, etc. Flying antenna parts mightstrike nearby personnel.

SCOPEThis pocke t gu ide i s i n t ended fo r use by t r a inedSINCGARS Ground NON-ICOM radio Operators.

It covers Operator tasks and provides flow charts showing stepsrequired to perform Operator functions. It serves as a handymemory jogger to help trained Operators follow required

procedures.

It also provides guidance on how to respond to jamming and anOperator Troubleshooting Checklist.

Whenever more Information is needed, or when performingPre-Mission Checks, refer to the Operators Manual(TM 11-5820-890-10-3).

JAMMING AND ANTIJAMMING Continued

FREQUENCY HOPPING OPERATION. Continued

SYMPTOM

SIG marker is litand showing a sig-nal higher than 3.You hear a con-stant hiss or back-ground noise in thehandse t , bu t noreal noise or radiotraffic.

POSSIBILITIES

(1) There is a com-promised or cap-tured RT in yournet. The compro-mised RT is con-stantly transmittingto act as a jam-mer.

(2) There is a stuckmike or bad hand-set in your net thatis locked in thetransmit (push-to-talk) position.

(3) Your RT has astuck handset ifyou blow or speakinto the mike andyou hear sidetone.

ACTION

(1) Press handsetp u s h - t o - t a l k 2times. If voice ordata transmissionsreturn, continue tooperate. ContactNCS or refer toSOI. Use authenti-

cation procedures.

(2) Push handsetp u s h - t o - t a l k 2times. ContactNCS. Use authen-tication proce-dures.

(3) Disconnecthandset from RTand the SIG markerdrops to LO or be-low. Press handsetpush-to-talk sev-eral times to free

the switch. If youreconnect thehandset and theSIG marker lights,r ep lace the badhandset with onethat is good.

by or to reduce RFpower. Attempt tomove your RT orantenna 50 metersor more. ContactNCS.

Note: When a station operating in plain text calls one opera-ting in cipher text, the receiving operator can hear the mes-sage and the beeping in the background. This tells the re-ceiving operator that the sender is broadcasting in plaintext.

O P E R ATO R S T R O U B L E S H O O T IN G C H E C K L IS TIf you have difficulty communicating, take the time to performthe following checks before you decide that there is somethingwrong with your radio.

Make sure you have all the switches set properly.

Check all cable connections to ensure that theyare tight.

Make sure that the antenna is properly connectedand positioned.

Try to verify that you have LOS with other stations.

Change position to see if communications improve.If you have not heard net traffic in some time, per-form passive late net entry.

Make sure your radio has adequate power (espe-cially manpack).

Look and see if another net station is co-located in

your area (called co-site interference).Determine if you are being jammed by the enemy.If so, take appropriate action.

Should your radio give you a strange, unexplained

wait for GOOD. Now run self-test. If GOOD results,reload radio and and re-enter net. If problem still ex-ists, contact unit maintenance.

If you still cannot communicate, there maybe something wrongwith your radio. However, any one of the above operator trouble-shooting actions may put you back into communications. Theyare well worth trying.

WARNING

A Iithium battery used with your manpack radio containspressurized sulfur dioxide gas. The gas is toxic, and thebattery MUST NOT be abused in any way which maycause the battery to rupture.DO NOT heat, short circuit, crush, puncture, mutilate,or disassemble batteries.DO NOT USE any battery which shows signs of damage,such as bulging, swelling, disfigurement, a brown Iiquidin the plastic wrap, a swollen wrap, etc.DO NOT test lithium batteries for capacity.DO NOT recharge lithium batteries.

DO NOT dispose of Iithium batteries with ordinary trash/refuse. Turn in discharged batteries to local supply.If the battery compartment becomes hot to the touch,if you hear a hissing or burping (i.e. battery venting), orsmell irritating gas (sulfur dioxide), IMMEDIATELY TURNOFF the equipment and leave the area.1. Allow the equipment to cool at least one hour.2. Remove and replace the battery after the equipment

has cooled to the touch,

3. If there is a safety incident, or if you believe a safetyhazard exists, notify your local Safety Office/Officer,file a Product Quality Deficiency Report. SF Form368, and notify the CECOM Safety Office, Ft. Mon-mouth, NJ at AV 995-3112.

DO NOT use a HaIon type fire extinguisher on a Iithiumbattery fire.In the event of a fire near a Iithium battery (ies), rapidcooling of the battery (ies) is important. Flood the equip-ment with water, or use a carbon dioxide (CO 2) extin-guisher. Control of the equipment fire and cooling mayprevent the battery from venting and potentially exposingIithium metal. In the event that the lithium metal becomesinvolved in fire, the use of a graphite based Class D fireextinguisher is recommended.DO NOT store batteries in unused equipment.DO NOT store Iithium batteries with other hazardousmaterials. Keep them away from open flame or heat.
