ROUTINE CHECKS
These routine checks should be done in addition to the scheduled PMCS. Always
do routine checks whenever you see the need or while performing a PMCS. If a prob-
lem is found during a check, get unit maintenance to repair it. Visually inspect the
equipment often.
Antennas
l Make sure antennas are clean.
l Check antenna elements for damage.
l
If you have a vehicular antenna base, make sure the braided strap (ground
strap) is securely installed to the vehicle and antenna base.
Cables and cable connectors
l Check cables (where visible) for cuts, cracks, and breaks.
l Make sure cable connectors are secure.
l Make sure cable connectors are securely attached to cables.
Controls and switches
l
Make sure each control moves smoothly while you operate your radio.
l
If a switch has detents, make sure each position has a solid feel to it.
l
Make sure pull-and-turn switches cannot move to a guarded position without
first being pulled out.
l Make sure all knobs are secure on their shafts.
Mounting and assembly hardware
l Check for loose nuts, bolts, and screws.
l Check for corrosion, rust, and deterioration of all metal parts.
l
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.
CLEANING
Keep radio controls and connectors as clean as you can, especially the display win-
dow and keyboard.
