usage time is
short
• Has this terminal been out
of the network service area
for a long time? As this
terminal searches for radio
waves in order to enable
communication when out of
the network service area,
more battery is consumed
than usual.
• The operating time of the
battery pack varies depending
on operating environment and
degradation of the battery
pack.

consumable accessory. Every
time you repeat the charging
of battery pack, usable time

When the usage time has
become extremely short even
