NEVER connect the transceiver to a power source using
reverse polarity, This connection will ruin the transceiver.
NEVER allow children to touch the transceiver.
AVOID using or placing the transceiver in direct sunlight
or in areas with temperatures below —10°C (+14°F) or
above +50°C (+122°F).
BE CAREFUL! When transmitting for a long time, the
rear panel will become hot.
BE CAREFUL! The use of non-Icom battery packs and
chargers may impair transceiver performance and inval-
idate the warranty.

cation appears, unplug the connector from
this jack. More than approx. 18 V DC has
been connected, so
the transceiver may
need checking at a

PRE-OPERATION
li Battery pack charging
Charge the battery pack before first operating the trans-
ceiver and when the low battery indicator appears.
li Battery pack precautions
NEVER throw a battery pack into a fire.
NEVER expose the battery pack to water.
NEVER short the metal terminals of a battery pack.
DO NOT attempt to charge a fully charged battery pack.
DO NOT discharge a battery pack completely.
AVOID overcharging. Disconnect the wall charger or power
cable within 48 hrs.
Charging may not occur in extreme cold (under 0°C;
+ 32°F ) or extreme heat (over + 40°C; + 104°F ).
i About the battery pack
©} Operating period
Operating period of the CM-166 (12 V, 600 mA) is approx.
5 hours.
CONDITION: 5% Tx / 5% Rx / 90% Standby (squelched).
The operating period is an estimate and varies depending
on temperature, etc.
© Battery memory effect
Full charge capacity may become lower when repeatedly
recharging after only partial discharging. If this occurs,
discharge almost completely through normal use before
recharging.
} Battery pack life
When the operating period becomes extremely short even
after charging the battery pack fully, a new battery pack is
needed.
