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.
NEVERconnect 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.

iv
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.

■Battery caution
• CAUTION! NEVER short the terminals of the battery pack (or
charging terminals of the transceiver). Also, current may flow into
nearby metal objects such as a necklace, so be careful when plac-
ing battery packs (or the transceiver) in handbags, etc.
Simply carrying with or placing near metal objects such as a neck-
lace, 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. 57).

■Battery charging
DRegular charging with the BC-146
The optional BC-146 provides regular charging of an optional bat-
tery pack with/without transceiver. The following is additionally re-
quired:
• An optionalAC adapter. (An AD-99 is supplied with BC-146.)
Check orienta-
tion for correct
charging. (In-
sert together
with AD-99.)
Turn power OFF.

DAbout AD-99
Attach the spacer (Spacer B/C) to the adapter (Spacer A) with ori-
entation as illustrated in the diagram below.
• Attach the spacer (Spacer B/C) to the adapter with the orientation
of the stamp “ ” pointing up.
When removing the spacer (Spacer B/C),
push the notch carefully
with your finger to remove the spacer (Spacer B/C) from the adapter
(Spacer A).
RCAUTION!
DO NOT push or force the notch with a screw driver, etc., to re-
move it.
DO NOT bend the notch when the adapter and spacer are not
joined together. This will cause weakening of the notch plastic.
Both cases may break the notch and it may not be able to be
reattached. 12
