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:
+10°C to +40°C (50°F to 140°F).
• Use the supplied charger or optional charger
(BC-119/BC-121 for
rapid charging, BC-137 #02 for regular charging)
only. NEVER use
other manufacturers’ chargers.
The optional BP-209 or BP-210 battery packs include rechargeable
Ni-Cd (Ni-MH: BP-210) batteries and can be charged approx. 300
times. Charge the battery pack before first operating the transceiver
or when the battery pack becomes exhausted.
If you want to charge the battery pack more than 300 times, the fol-
lowing points should be observed:
• Avoid over charging. The charging period should be less than
48 hours.
• Use the battery until it becomes almost completely exhausted
under normal conditions. We recommend battery charging 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.
