In place of the battery pack, you can use 3 AA batteries. Use
high quality alkaline batteries to enjoy longer periods of
battery life.
Average battery life using low power: 8 hours
Average battery life using high power: 4 hours
•Average times are calculated using 5% transmit time, 5% receive
time, and 90% standby time.

◆ Do not mix old and new batteries or batteries of different types.
◆ When you do not use the transceiver for an extended period of
time, remove the batteries from the transceiver.
5
CHARGING THE BATTERY PACK
Initially charging the battery pack after purchase or extended
storage (greater than 2 months) will not bring the battery pack
to its normal operating capacity. After repeating the charge/
discharge cycle two or three times, the operating capacity will
increase to normal.
◆ Do not recharge the battery pack if it is already fully charged.
Doing so may cause the life of the battery pack to shorten or the
battery pack may be damaged.
◆ After recharging the battery pack, disconnect it from the charger.
Charging the battery pack for more than 5 days may reduce the
battery pack life due to overcharging.
Note:
◆ The ambient temperature should be between 41°F and 104°F
(5°C and 40°C) while charging is in progress. Charging outside
this range may not fully charge the battery.
◆ Always switch OFF the transceiver equipped with a battery pack
before charging. Using the transceiver while charging its battery
pack will interfere with correct charging.
◆ The battery pack life is over when its operating time decreases
even though it is fully and correctly charged. Replace the battery
pack.
