RDANGER! NEVER short the terminals of the battery
pack. Also, current may flow into nearby metal objects, such
as a necklace, etc. Therefore, be careful when carrying with,
or placing near metal objects, carrying in handbags, etc.
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
the battery to burst.
RWARNING! 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
(2 to 4 inches ) away from the lips and the transceiver is verti-
cal.
RWARNING! 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.
CAUTION: NEVER connect the transceiver to an AC
outlet or to a power source of more than 11.5 V DC. Such a
connection will damage the transceiver.
CAUTION: NEVER connect the transceiver to a power
source that is DC fused at more than 5 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 ruined.
DO NOT allow children to play with any radio equipment
containing a transmitter.
DO NOT operate the transceiver near unshielded electri-
cal blasting caps or in an explosive atmosphere.
DO NOT use or place the transceiver in direct sunlight or
in areas with temperatures below –10°C (+14°F) or above
+60°C (+140°F).
Even when the transceiver power is OFF, a slight current still
flows in the circuits. Remove the battery pack or case from
the transceiver when not using it for a long time. Otherwise,
the battery pack or installed Alkaline cell batteries will be-
come exhausted.
