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
ASTRO Digital XTS 2500 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.
