SECTION V. OPERATOR TROUBLESHOOTING
OPERATOR’S TROUBLESHOOTING CHECKLIST
If you have difficulty communicating, take the time to perform the following checks
before you decide that there is something wrong with your radio.
Make sure you have all switches set properly.
Check all cable connections to ensure that they are tight.
Make sure your antenna is properly connected and positioned.
Try to verify that you have LOS with other stations.
Change position to see if communications improve.
If you have not heard traffic in some time, perform passive late net entry.
Make sure your radio has adequate power (especially 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 message which does not
automatically clear:
(1)
Set FCTN to
then return to SQ ON. This action may clear your
problem.
(2)
If it does not, and the situation permits, set FCTN to
and wait for
GOOD, then to
and wait 10 seconds, then back to
and again
wait for GOOD. Now run self-test. If GOOD results, reload radio and re-
enter net. If problem still exists, contact unit maintenance.
If you still cannot communicate, there may be something wrong with your radio. How-
ever, any one of the above operator troubleshooting actions may put you back into
communications. They are well worth trying.
OPERATORS: Two important rules to follow are:
(1) Never use the "TIME" control!
(2) Never set MODE to
(Violating either of these rules can take you out
of the net, and possibly stop your entire net from
communicating.)
