ter, and dry it before operating. Otherwise, the transceiver’s
keys, switches and controllers may become unusable, due
to salt crystallization.
Icom is not responsible for the destruction or damage to the

quakes, storms, floods, lightnings, or other natural disas-
ters, disturbances, riots, war, or radioactive contamination.

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 or connector cover is cracked or broken, or the trans-
ceiver has been dropped.
