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.

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.
