BATTERY CHARGING
New2001
■ Optional battery case
➥ Install 2 × LR6 (AA) size
alkaline batteries into the
optional BP-257 BATTERY
CASE.
• Be sure to observe the cor-
rect polarity.
A built-in step-up convertor in the BP-257 increases the
voltage to 5 V DC.
Approx. 100 mW of output power is possible with the
BP-257 operation. Also, no transmit output power selec-
tion is available.
Keep battery contacts clean. It’s a good idea to clean bat-
tery terminals once a week.
D Battery information
The batteries may seem to have low capacity when used in
low temperatures such as –10°C or below. Keep the battery
case or pack warm in this case.
D Battery replacement
When the batteries become exhausted, the function display
may blink or have a lower contrast. In these cases, replace
all batteries with new, same brand, alkaline batteries.
■ Battery information
D Battery life
The transceiver operates with the BP-256 Li-ion as follows.
However, when operating in DV mode, operating time may
be shortened by one-half hour.
• VHF band : Approx. 6 hours
• UHF band : Approx. 5.5 hours
(Tx: Rx: Stand-by=1: 1: 8)
Even when the transceiver power is OFF, a small current
still flows in the radio. Remove the battery pack or case
from the transceiver when not using it for a long time. Oth-
erwise, the battery pack or installed batteries will become
exhausted.
The battery protection function sets to Low (2.5 W) auto-
matically while using 0°C. Transmit power selection is also
disable.
D Battery indicator
The battery indicator, “ ,” appears only when the BP-256
Li-ion is attached to the transceiver.
The battery indicator does not appear when turning power
ON after charging is completed without disconnecting the
battery charger or external DC power.
Indication Battery condition
The battery has ample capacity.
The battery is nearing exhaustion. Charging is neces-
sary.
