ABOUT CE
CE Versions of the IC-F31GT/GS, ICF41GT/GS which display the “CE” symbol on
the serial number seal, comply with the essential requirements of the European Radio
and Telecommunication Terminal Directive
1999/5/EC.
This warning symbol indicates that this equipment operates in nonharmonised frequency bands and/or may be subject to licensing
conditions in the country of use. Be sure to check that you have the
correct version of this radio or the correct programming of this radio,
to comply with national licensing requirements.
INSTALLATION NOTES
• When transmitting with a portable radio, hold the radio in a vertical
position with its microphone 5 to 10 centimeters away from your
mouth. Keep the antenna at least 2.5 centimeters 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 centimeters from your body when transmitting.
i
IMPORTANT
R 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.
R CAUTION! NEVER operate the transceiver with a headset or
other audio accessories at high volume levels.
R CAUTION! NEVER short the terminals of the battery pack.
DO NOT push the PTT when not actually desiring to transmit.
AVOID using or placing 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 operation, or after being placed in extremely cold areas.
DO NOT modify the transceiver for any reason.
KEEP the transceiver from the heavy rain, and Never immerse it in
the water. The transceiver construction is water resistant, not waterproof.
The use of non-Icom battery packs/chargers may impair transceiver
performance and invalidate the warranty.

Battery 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 necklace, etc. causes shorting. This will damage not only the battery
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 be-
comes 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
overnight. Then, fully charge the battery pack again. If the battery
pack still does not retain a charge (or only very little charge), a new
battery pack must be purchased. (p. 9)
