6 - 2 MTP700 Portable Radio / Detailed Service Manual 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 tis-
sue 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-pres-
sure air to hasten the drying process since this could cause the liquid to collect in
unwanted places. After completing of the cleaning process, 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 contamina-
tion by dissolved material (from previous usage).
