MAINTENANCE

Preventive Maintenance

This TETRA Handportable Terminal does not require a scheduled preventive
maintenance program. However, periodic visual inspection is recommended.

Inspection

Check that the external surfaces of the radio are clean, and that all external
controls and switches are functional. It is not recommended to inspect the interior
electronic circuitry.

Cleaning

The following procedures describe the recommended cleaning agents and
methods to be used when cleaning the external and internal surfaces of the
radio. External surfaces should be cleaned whenever a periodic visual inspection
reveals the presence of smudges, compound, or grime. Internal surfaces (circuit
boards and components) should be cleaned only when the radio is disassembled
for servicing or repair.
The only recommended agent for cleaning external radio surfaces is a 0.5%
solution (one teaspoon of detergent per gallon of water) of mild dishwashing
detergent in water. The internal surfaces should be cleaned only with isopropyl
alcohol (100% by volume).
NOTE:

Internal surfaces should be cleaned only when the radio is disassembled
for service or repair.
Take care to clean the bottom connector frequently and particularly prior
to the programming procedure e.g. with a soft brush (do not use fluids).
CAUTION: The effects of certain chemicals and their vapors can have
harmful results on certain plastics. Avoid using aerosol sprays, tuner
cleaners, and other chemicals.
