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 problem is found during a check, get unit maintenance to repair it. Visually
inspect the equipment often.
Antennas
Make sure antennas are clean.
Check antenna elements for damage.
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
Check cables (where visible) for cuts, cracks, and breaks.
Make sure cable connectors are secure.
Make sure cable connectors are securely attached to cables.
Controls and switches
Make sure each control moves smoothly while you operate your radio.
If a switch has detents, make sure each position has a solid feel to it.
Make sure pull-and-turn switches cannot move to a guarded position without first being pulled out.
Make sure all knobs are secure on their shafts.
Mounting and assembly hardware
Check for loose nuts, bolts, and screws.
Check for corrosion, rust, and deterioration of all metal parts.
Should your radio give you a strange, unexplained message which does not automatically clear:
(1)
Set FCTN to OFF, then return to SQ ON. This action may clear your problem.
(2)
If it does not, and the situation permits, set FCTN to 'Z-A and wait for "Good", then to ST1W and wait 10
seconds, then back to Z1-A 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 window and keyboard.
