MAINTENANCE

The M-PA radio is a very reliable unit and will normally
provide many years of trouble-free service. The recom-
mended Preventive Maintenance procedures that follow
should be performed when a technician comes in contact
with a unit. Component level troubleshooting information is
contained in the Service Section.

PREVENTIVE MAINTENANCE

Antenna
The antenna and antenna contact should be kept clean
and free from dirt or corrosion. If the antenna contact should
become dirty or corroded, communication range could be
reduced.
Battery Packs
Insure the battery packs are properly maintained. Do
not over or under charge them on a regular basis. Verify the
contacts are clean and free of corrosion.
Mechanical
Since portable radio units are subject to shock and vi-
bration, check for loose plugs, knobs, screws, etc.
Transmitter Check
Check transmit frequency and deviation. Normally
these checks are made when the unit is first put into opera-
tion. They should be repeated after the first month of opera-
tion, then annually.
Receiver Check
Receiver sensitivity should be checked periodically as
an indication of overall receiver operation.
Cleaning
If the unit requires an external cleaning use mild soap
and a damp cloth. Avoid abrasive cleaners or chemicals
which may damage the plastic or rubber surfaces on the
unit.
