PRECAUTIONS

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 away from the

lips and the transceiver is vertical.

RWARNING! NEVER operate the transceiver with a

headset or other audio accessories at high volume levels. Hear-

ing experts advise against continuous high volume operation. If

you experience a ringing in your ears, reduce the volume or dis-

continue use.

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, but higher fuse values will not give any

protection against such accidents and the transceiver will be ru-

ined.

NEVER attempt to charge alkaline or dry cell batteries. Be

aware that external DC power connections will charge batteries

inside the battery case. This will damage not only the battery

case but also the transceiver.

DO NOT push the PTT when not actually desiring to trans-

mit.

Place the unit in a secure place to avoid inadvertent use by chil-

dren.

IC-T3H.qxd 03.2.6 10:18 Page iii (1,1)

DO NOT operate the transceiver near unshielded electrical

blasting caps or in an explosive atmosphere.

AVOID using or placing the transceiver in direct sunlight or in

areas with temperatures below –10°C or above +60°C.

The use of non-Icom battery packs/chargers may impair trans-

ceiver performance and invalidate the warranty.

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 bat-

tery pack or installed Ni-Cd batteries will become exhausted.
