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-119N/BC-
121N/BC-144N for rapid charging, BC-146 for regular charging)
only.
NEVER
use other manufacturers’ chargers.
The optional BP-209N, BP-210N, BP-211N or BP-222N battery
packs include rechargeable Ni-Cd (Ni-MH: BP-210N, Li-Ion: BP-
211N) batteries and can be charged approx. 300 times. Charge the
battery pack before first operating the transceiver or when the bat-
tery pack becomes exhausted.
If you want to charge the battery pack more than 300 times, the fol-
lowing points should be observed:
•
Avoid overcharging
— batteries must be removed from the
charger to stop charging. Batteries should not be charged for
more than 15 hours after the LED indicator turns green.
• Use the battery until it becomes almost completely exhausted
under normal conditions.

Recommendation for Li-Ion battery packs:
Li-Ion batteries are different from Ni-Cd batteries in that it is not
necessary to completely charge and discharge them to prolong
the battery life. Therefore, charging the battery in intervals, and
not for extended periods is recommended.

Battery pack life
When the operating period becomes extremely short even after
charging the battery pack fully, a new battery pack is needed.
NOTE:
The charger rapidly charges a battery pack to a specified
level, not a completed level, to prevent overcharging. Leave the bat-
tery pack in the charger for a few more hours (up to 15 hours; de-
pending on battery condition) after the LED indicator turns green, to
charge the battery completely.
