Introduction 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.
General
Maintenance
In order to avoid operating outside the limits set by the FCC, it is
recommended that the ASTRO Digital XTS 5000 radio’s reference oscillator be
aligned every time the radio is taken apart, or once per year, whichever comes
first. Periodic visual inspection and cleaning is also recommended.
For XTS 5000R Radios - It is recommended that radio submergibility be
checked annually by qualified service personnel.
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 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.
