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
DV mode
Approx. 7.5 hrs.
Approx. 7 hrs.

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.
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 internal
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 be-
fore 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.
TIP:
A built-in step-up converter in the BP-273 in-
creases the voltage to 5.5 V DC.
Approximately 100 mW of output power is possi-
ble with the BP-273 operation. Also, the transmit
output power selection is disabled.
TIP:
When the BP-273 battery case is attached to
the transceiver, the battery icon cannot display the
battery capacity of the alkaline batteries. The battery
icon stays “
点滅
ᐜ㔞⾲♧
㟁⾲♧
,” and it does not reflect with the true
battery capacity.
NOTE:
• The battery life may differ, depending on the operat-
ing 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.
