vertent use by children.

 push the PTT when not actually intending to 

transmit.

use or place the transceiver in direct sunlight or 

in areas with temperatures below –20°C (–4°F) or above 

 

+55°C (+131°F).

place the transceiver in excessively dusty envi-

ronments.

place the transceiver against walls. This will ob-

struct heat dissipation.

use chemical agents such as benzine or alcohol 

when cleaning, as they damage the transceiver surfaces.

operating continuously for long periods.

PRECAUTIONS

ii

R WARNING! NEVER

 

operate the transceiver with 

a headset or other audio accessories at high volume levels. 
Hearing experts advise against continuous high volume op-
eration. If you experience a ringing in your ears, reduce the 
volume level or discontinue use.

R WARNING! NEVER

 

connect the transceiver to an 

AC outlet or to a power source of more than 28 V DC. Such 
a connection will damage the transceiver.

connect the transceiver to a 

power source that is DC fused at more than 10 A. Accidental 
reverse connection will be protected by this fuse, higher fuse 
values will not give any protection against such accidents 
and the transceiver will be damaged.

operate the transceiver near unshielded electri-

cal blasting caps or in an explosive atmosphere.

 connect the transceiver to a power source using 

reverse polarity. This connection will not only blow fuses but 
also may damage the transceiver.

FCC caution: Changes or modifications to this transceiver, 
not expressly approved by Icom Inc., could void your authority 
to operate this transceiver under FCC regulations.
