PREPARATION
CHARGING THE BATTERY PACK
The battery pack is not charged at the factory; charge it before
use. Average battery pack life (calculated using 5% transmit
time, 5% receive time, and 90% standby time) is 15 hours.
Note:
◆ The ambient temperature should be between 32°F and 104°F
(0°C and 40°C) while charging is in progress. Charging outside
this range may not fully charge the battery.
◆ The battery pack life is over when its operating time decreases even
though it is fully and correctly charged (approximately 500 cycles).
Replace the battery pack.
◆ While operating the transceiver using a Li-ion battery pack in
areas with an ambient temperature close to 0°C, the operating
time may be shortened.
◆ We recommend using a short USB cable (low loss) for charging.
ATTENTION: Switch OFF a transceiver equipped with a battery
pack before charging.

Charging with a USB Cable
