EXPLICIT DEFINITIONS
WORD DEFINITION
RDANGER! Personal death, serious injury or an explo-
sion may occur.
RWARNING! Personal injury, fire hazard or electric shock
may occur.
CAUTION Equipment damage may occur.
NOTE
If disregarded, inconvenience only. No risk

PRECAUTIONS
RDANGER! NEVER short the terminals of the battery pack.
RWARNING! NEVER hold the transceiver so that the an-
tenna is very close to, or touching exposed parts of the body, es-
pecially 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 head-
set or other audio accessories at high volume levels.
CAUTION: NEVER use non-Icom battery packs/chargers to
prevent the loss of the transceiver’s good performance and warranty.
DO NOT push the 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.
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.
Approved Icom optional equipment is designed for optimal perfor-
mance when used with an Icom transceiver.
Icom is not responsible for the destruction or damage to an Icom
transceiver in the event the Icom transceiver is used with equip-
ment that is not manufactured or approved by Icom.

BATTERY PACKS
■Battery cautions
RDANGER! 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
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.
RDANGER! NEVER incinerate used battery packs. Internal
battery gas may cause an explosion.
RWARNING! NEVER immerse the battery pack in water. If the
battery pack becomes wet, be sure to wipe it dry BEFORE attach-
ing it to the transceiver.
Clean the battery terminals to avoid rust or miss contact.
Keep battery terminals 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. 5)

■Charging caution
Prior to using the transceiver for the first time, the battery pack
must be fully charged for optimum life and operation.
• Recommended temperature range for charging:
Between +10°C and +40°C.
• Use the optional charger (BC-119N/BC-121N/BC-144N for rapid
charging, BC-137 #11/BC-146 for regular charging) only. NEVER
use other manufacturers’ chargers.
The battery pack contains a rechargeable battery.
Charge the battery pack before first operating the transceiver, or
when the battery pack becomes exhausted.
If you want to prolong the battery life, the following points should
be observed:
• Avoid over charging. The charging period should be less than
20 hours.
• Use the battery pack until it becomes almost completely ex-
hausted under normal conditions. We recommend battery charg-
ing after transmitting becomes impossible.
DBattery pack life
When the operating period becomes extremely short even after
charging the battery pack fully, a new battery pack is needed.

BATTERY PACKS
■Battery case (Option)
When using the optional battery case, install 6 × AA (LR6) size
alkaline batteries as illustrated below.
NOTE: Output power is automatically reduced to 1 W to retains suf-
ficient power in case of emergency, etc.
CAUTIONS:
• When installing batteries, make sure they are all the same
brand, type and capacity. Also, do not mix new and old batteries
together.
• Keep the battery terminals clean. It’s a good idea to clean the
battery terminals once a week.
• Never incinerate used battery cells since internal battery gas
may cause them to rupture.
• Never expose a detached battery case to water. If the battery
case gets wet, be sure to wipe it dry before using it.

■General
In the following explanations, programmable function names are
bracketed, the specific switch used to activate the function depends
on programming.

lected.
DSCAN FUNCTION
The scan function allows you to search a pre-programmed group of
channels for signals.
Push the [SCAN] switch to start/stop scan.
• Scan pauses on a channel when receiving a signal.
• Depending on programming, a message may appear while scanning.
• “Lockout SCAN” (pre-programmed list SCAN) or “Priority SCAN” can
be pre-programmed.
• When the “Power-save function” is activated, the transceiver checks
all pre-programmed channels then returns to the “Power-save func-
tion” again.
