Cleaning

68P02963C70-O
This portable radio does not require a scheduled preventive maintenance program. However,
periodic visual inspection is recommended.
Inspect the radio's external surfaces. A detailed inspection of interior circuitry is not needed
or recommended.
The following procedures describe the recommended cleaning agents and methods to be used
when cleaning the external and internal surfaces of the radio. External surfaces should be
cleaned whenever a periodic visual inspection reveals the presence of smudges, compound,
or grime. Internal surfaces (circuit boards and components) should be cleaned only when the
radio is disassembled for servicing or repair.
The only recommended agent for cleaning external radio surfaces is a 0.5% solution (one tea-
spoon of detergent per gallon or four litres of water) of mild dishwashing detergent in water.
The internal surfaces should be cleaned only with isopropyl alcohol (70% by volume).
