• Be sure to observe the cor-
rect polarity.
A built-in step-up converter in the BP-216 increases the
voltage to 5 V DC.
Approx. 100 mW of output power is possible with the
BP-216 operation. Also, no transmit output power selec-
tion (TX inhibit) is available.
Keep battery contacts clean. It’s a good idea to clean bat-
tery terminals once a week.

Battery information
The batteries may seem to have low capacity when used in
low temperatures such as –10°C (+14°F) or below. Keep the
batteries warm in this case.
D
Battery replacement
When the batteries become exhausted, the function display
may blink or have a lower contrast. In this cases, replace all
batteries with new, same brand, alkaline batteries.

Battery life
The transceiver operates with the BP-217 Li-ion as follows.
When operating in DV mode, operating time may be short-
ened by one-half hour.
•
VHF band
: Approx. 6.5 hours
•
UHF band
: Approx. 6.0 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 transceiver to Low
power (0.5 W) automatically when temperature is 0°C
(+32°F) or below. In this case, transmit power selections
(Hi/Mid) are also disable.
D
Battery indicator
The battery indicator, “
,” appears only when the BP-217
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.
