EXPLICIT DEFINITIONS
WORD DEFINITION
RWARNING Personal injury, fire hazard or electric shock
may occur.
CAUTION Equipment damage may occur.
NOTE
If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.
INSTALLATION NOTES
• When transmitting with a portable radio, hold the radio in a verti-
cal position with its microphone 5 to 10 cm away from your mouth.
Keep the antenna at least 2.5 cm from your head and body.
• If you wear a portable two-way radio on your body, ensure that the
antenna is at least 2.5 cm from your body when transmitting.
PRECAUTIONS
CAUTION! NEVER hold the transceiver so that the antenna
is very close to, or touching exposed parts of the body, especially
the face or eyes, while transmitting. The transceiver will perform
best if the microphone is 5 to 10 cm away from the lips and the
transceiver is vertical.
CAUTION! NEVER operate the transceiver with a headset or
other audio accessories at high volume levels.
CAUTION! NEVER short the terminals of the battery pack.
CAUTION! NEVER use non-Icom battery packs/chargers to
prevent the loss of the transceiver’s good performance and warranty.
DO NOT push [PTT] when not actually desiring to transmit.
DO NOT use or place the transceiver in direct sunlight or in
areas with temperatures below –10°C or above +50°C.
The basic operations, transmission and reception of the transceiver,
are guaranteed within the specified operating temperature range
(depending on version). However, the LCD display may be operate
correctly, or show an indication in the case of long hours of opera-
tion, or after being placed in extremely cold areas.
DO NOT modify the transceiver. The transceiver warranty does
not cover any problems caused by unauthorized modification.
KEEP the transceiver from heavy rain, and NEVER immerse it
in the water. The transceiver construction is water resistant, not
waterproof.

nBattery cautions
• CAUTION! NEVER short terminals (or charging terminals) of the
battery pack. Also, current may flow into nearby metal objects
such as a necklace, so be careful when placing battery packs (or
the transceiver) in handbags, etc.
Simply carrying with or placing near metal objects such as a neck-
lace, etc. may cause shorting. This may damage not only the bat-
tery pack, but also the transceiver.
•
NEVER incinerate used battery packs. Internal battery gas may
cause an explosion.
•
NEVER immerse the battery pack in water. If the battery pack
becomes wet, be sure to wipe it dry BEFORE attaching it to the
transceiver.
• Clean the battery terminals to avoid rust or miss contact.
•
Keep battery contacts clean. It’s a good idea to clean battery ter-
minals once a week.
If your battery pack seems to have no capacity, even after being
charged, completely discharge it by leaving the power ON over-
night. Then, fully charge the battery pack again. If the battery pack
still does not retain a charge (or only very little charge), a new bat-
tery pack must be purchased. (p. 22)
