Charging NOTE
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:
B10°C and +40°C
• Use the supplied charger or 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 rechargable 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 48
hours.
• Use the battery pack until it becomes almost completely ex-
hausted, under normal conditions. We recommend battery charg-
ing after transmitting becomes impossible.

Battery pack life
When the operating period becomes extremely short, even after
charging the battery pack fully, a new battery pack is needed.
