MAINTENANCE
Cleaning External Plastic Surfaces
Apply the 0.5% detergent-water solution sparingly with a stiff, non-metallic, short-bristled brush to
work all loose dirt away from the radio. Use a soft, absorbent, lintless cloth or tissue to remove the
solution and dry the radio. Make sure that no water remains entrapped near the connectors, cracks,
or crevices.
Cleaning Internal Circuit Boards and Components
Isopropyl alcohol (70%) may be applied 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 the 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 this could cause the liquid to collect in unwanted places. After completing of the cleaning proc-
ess, use a soft, absorbent, lintless cloth to dry the area. Do not brush or apply any isopropyl alcohol
to the frame, front cover, or back cover.
NOTE:
Always use a fresh supply of alcohol and a clean container to prevent contamination
by dissolved material (from previous usage).
