BE CAREFUL! The transceiver meets IP67 require-

ments for dust-tight and waterproof protection. However, once

the transceiver has been dropped, dust-tight and waterproof

protection cannot be guaranteed because of possible dam-

age to the transceiver’s case or the waterproof seal.

Even when the transceiver power is OFF, a slight current still

ﬂows in the circuits. Remove the battery pack or batteries from

the trans ceiver when not using it for a long time. Otherwise,

the installed battery pack or batteries will become exhausted,

and will need to be recharged or replaced.

MAKE SURE to turn OFF the transceiver power before

connect ing the supplied/optional equipment.
