Maintenance
This chapter provides information about the care and maintenance of this radio.
5.1
Preventive Maintenance
Periodic visual inspection and cleaning are recommended.
Inspection
Check that the external surfaces of your radio are clean, and that all external controls and switches are
functional. It is not recommended to inspect the interior electronic circuitry.
Cleaning Procedures
The following procedures describe the recommended cleaning agents and the methods to clean the external
and internal surfaces of your radio.
External surfaces include the front cover, housing assembly, and battery. These surfaces should be cleaned
whenever a periodic visual inspection reveals the presence of smudges, grease, and/or grime.
CAUTION: Use all chemicals as prescribed by the manufacturer. Follow all safety precautions as
defined on the label or material safety data sheet. The effects of certain chemicals and their vapors can
have harmful results on certain plastics. Avoid using aerosol sprays, tuner cleaners, and other
chemicals.
NOTE:
Only clean internal surfaces when your radio is disassembled for service or repair.
Before any programming procedure and to ensure optimum performance of the bottom connectors, use
a soft brush to clean the bottom connectors (do not use fluids).
Cleaning External Plastic Surfaces
IMPORTANT: The only recommended agent for cleaning the external radio surfaces is a 0.5% solution
of a mild dish-washing detergent in water.
Apply the 0.5% detergent-water solution sparingly with a stiff, non-metallic, short-bristled brush to work all
loose dirt away from your radio. Use a soft, absorbent, lint-less cloth, or tissue to remove the solution and dry
your radio. Make sure that no water remains entrapped near the connectors, cracks, or crevices.
Cleaning Internal Circuit Boards and Components
IMPORTANT:
The only factory recommended liquid for cleaning the printed circuit boards and their components is
isopropyl alcohol (100% by volume).
Always use fresh supply of alcohol and a clean container to prevent contamination by
dissolved material (from previous usage).
Apply Isopropyl alcohol (100%) with a stiff, non-metallic, short-bristled brush to dislodge embedded or caked
materials located in hard-to-reach areas. The brush stroke should direct the dislodged material out and away
from the inside of your radio. Make sure that controls or tunable components are not soaked with alcohol.
Do not use high-pressure air to hasten the drying process since it can cause the liquid to collect in unwanted
