Service and cleaning
This chapter contains information on how to service and clean the radio set.
Care information
The recommendations below apply in the same way to the radio set, the battery, the
charger, and all accessories.
Do not use any chemicals, solvents or aggressive cleaning agents for cleaning the
radio set.
Do not paint the radio set. The paint may stick the moving parts together, thus pre-
venting proper unit operation.
Wipe off the housing with a moist cloth as required. Never use a dry cloth. This
involves a static charge hazard.
From time to time, carefully blow out all openings accessible from the outside and
the battery compartment.
The radio set is jet-proof. After contact with liquid, remove the water from the radio
set with an absorbent cloth. Knock the liquid out of the microphone opening.
