Introduction
to This Section
This section of the manual describes preventive maintenance and handling
precautions. Each of these topics provides information vital to the successful
operation and maintenance of your radio.
Preventive
Maintenance
The ASTRO Digital XTS 3000 radios do not require a scheduled preventive
maintenance program; however, periodic visual inspection and cleaning is
recommended.
Inspection Check that the external surfaces of the radio are clean, and that all external
controls and switches are functional. A detailed inspection of the interior
electronic circuitry is not needed.
Cleaning The following procedures describe the recommended cleaning agents and the
methods to be used when cleaning the external surfaces of the radio. External
surfaces include the housing assembly and battery case. These surfaces should
be cleaned whenever a periodic visual inspection reveals the presence of
smudges, grease, and/or grime.
The only recommended agent for cleaning the external radio surfaces is a 0.5%
solution of a mild dishwashing detergent, such as JOY®, in water.
Cleaning External
Plastic Surfaces
(The detergent-water solution should be applied sparingly with a stiff, non-
metallic, short-bristled brush to work all loose dirt away from the radio. A soft,
absorbent, lintless cloth or tissue should be used to remove the solution and
dry the radio. Make sure that no water remains entrapped near the connectors,
cracks, or crevices.
The effects of certain chemicals and their vapors can
have harmful results on certain plastics. Aerosol
sprays, tuner cleaners, and other chemicals should
be avoided.
