BATTERY CHARGING

■ Battery charging

Prior to using the transceiver for the ﬁrst time, the battery pack must

be fully charged for optimum life and operation.

CAUTION: To avoid damage to the transceiver, turn it OFF while

charging.

• Recommended temperature range for charging:

+10°C to +40°C (+50°F to +104°F)

- The Li-Ion battery functions within –20°C to +60°C (–4°F to

+140°F)

• Use the specified chargers (BC-119N, BC-121N and BC-160).

NEVER use another manufacturer’s charger.

• Use the optional AC adapter. NEVER use another manufacturer’s

AC adapter.

Recommendation:

Charge the supplied battery pack for a maximum of up to

10 hours. 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 in-

tervals, and not for extended periods is recommended.
