RECOMMENDATION
CLEAN THE TRANSCEIVER THOROUGHLY IN A BOWL
OF FRESH WATER after exposure to saltwater, and dry it
before operating. Otherwise, the transceiver's keys, switches
and controllers may become unusable, due to salt crystalliza-
tion, and/or the charging terminals of the battery pack may
corrode.
NOTE: IF the transceiver's waterproof protection appears
defective, carefully clean it with a soft, damp (fresh water)
cloth, then dry it before operating.
The transceiver may lose its waterproof protection if the
case, jack cap, or connector cover is cracked or broken, or
the transceiver has been dropped.
Contact your Icom distributor or your dealer for advice.
