RDANGER! NEVER short the terminals of the bat-
tery pack.
RDANGER! Use and charge only specified Icom battery
packs with Icom radios or Icom chargers. Only Icom battery
packs are tested and approved for use with Icom radios or
charged with Icom chargers. Using third-party or counterfeit
battery packs or chargers may cause smoke, fire, or cause

PRECAUTIONS

ii
CAUTION: MAKE SURE the flexible antenna and bat-
tery pack are securely attached to the transceiver, and that the
antenna and battery pack are dry before attachment.
Exposing the inside of the transceiver to water will result in
serious damage to the transceiver.
DO NOT operate the transceiver near unshielded electrical
blasting caps or in an explosive atmosphere.
DO NOT use harsh solvents such as benzine or alcohol
when cleaning, as they will damage the transceiver surfaces.
DO NOT push PTT when not actually intending to transmit.
DO NOT use or place the transceiver in direct sunlight or
in areas with temperatures below +22°F (–30°C) or above
+140°F (+60°C).
The basic operations, transmission and reception of the trans-
ceiver are guaranteed within the specified operating temper-
ature range. However, the LCD display may not be operate
correctly, or show an indication in the case of long hours of
operation, or after being placed in extremely cold areas.
DO NOT modify the transceiver for any reason. The trans-
ceiver warranty does not cover any problems caused by un-
authorized modification.
BE CAREFUL! The transceiver will become hot when op-
erating it continuously for long periods of time.
KEEP the transceiver away from the heavy rain, and Never
immerse it in the water. The transceiver construction is water
resistant*, not waterproof.
* Only when the supplied battery pack, flexible antenna and jack
cover are attached.
MAKE SURE to turn the transceiver power OFF before
connecting the supplied/optional equipment.

This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reason-
able protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in ac-
cordance with the instructions, may cause harmful interfer-
ence to radio communications. However, there is no guaran-
tee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to cor-
rect the interference by one or more of the following meas-
ures:
s 2EORIENT OR RELOCATE THE RECEIVING ANTENNA
s )NCREASE THE SEPARATION BETWEEN THE EQUIPMENT AND RE-
ceiver.
s #ONNECT THE EQUIPMENT INTO AN OUTLET ON A CIRCUIT DIFFER-
ent from that to which the receiver is connected.
