About the battery pack
D
Operating period
Depending on the attached battery pack, the operating period
of the transceiver varies. Refer to the last page for battery
pack specifications.
D
Battery pack life
If your battery pack seems to have no capacity even after
being fully charged, completely discharge it by leaving the
power ON overnight. Then, fully charge the battery pack
again.
If the battery pack still does not retain a charge (or very little),
a new battery pack must be purchased.

Installing batteries in the
battery case
When using a battery case, install 8 AA (R6) size Ni-Cd or al-
kaline batteries as illustrated below.
q
Remove the bat-
tery case from the
transceiver.
w
Install 8 AA (R6)
size Ni-Cd or alka-
line batteries.
• Be sure to observe
the correct polarity.
●
NEVER connect DC power to the transceiver when in-
stalling dry cell or alkaline batteries. Such a connection will
damage the transceiver.
●
Be careful of battery overcharging. When operating via ex-
ternal DC power, installed batteries are simultaneously
charged.
●
Keep battery contacts clean. It’s a good idea to clean bat-
tery terminals once a week.
