Charging the Battery Pack
The battery pack is not charged at the factory; charge it before use.
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.
CAUTION
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.
Note
The ambient temperature should be between 41 and 104°F (5 and
40) 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.
