BATTERY CHARGING

■ Optional battery case

When using the BP-273
(LR6) size alkaline batteries, as described below.
Remove the battery case if it is attached. (p. 1-2)
q
w Install three AA (LR6) size alkaline batteries.
• Install only alkaline batteries.
• Be sure to observe the correct polarity.
Attach the battery case. (p. 1-2)
e
A built-in step-up converter in the BP-273 increases
the voltage to 5.5 V DC.
Approximately 100 mW of output power is possible
with the BP-273 operation. Also, the transmit output
power selection is disabled.
CAUTION:
• When installing batteries, make sure they are all
the same brand, type and capacity. Also, do not mix
new and old batteries together.
• Keep the battery terminals clean. It's a good idea to
occasionally clean them.
• Never incinerate used battery cells since the inter-
nal battery gas may cause them to rupture.
• Never expose a detached battery case to water.
If the battery case gets wet, be sure to wipe it dry
before using it.
• Never use batteries whose insulated covering is
damaged.
• Remove the alkaline batteries when battery case is
not used. Otherwise the installed alkaline batteries
will exhausted due to built-in step-up converter.

D Battery life
The approximate battery life (operating time) as shown
below is calculated under the following assumptions;
• Power save setting: Auto (Short)
• Duty cycle: TX : RX : Stand-by = 1 : 1: 8 (based on
operating style)
FM mode
Approx. 7.5 hrs. Approx. 7 hrs.
NOTE:
• The battery life may differ, depending on the oper-
ating style or the installed alkaline batteries.
• 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 About the battery replacement

When the alkaline batteries are almost exhausted,
"LOW BATTERY" is displayed and the battery icon
starts to blink. After 10 seconds, the transceiver power
is automatically turned OFF.
In that case, replace all batteries with new alkaline bat-
teries.
When the BP-273 battery case is attached to the
transceiver, the battery icon cannot display the bat-
tery capacity of the alkaline batteries. The battery
点滅
icon stays " ," and it does not reflect with the true
battery capacity.
