Battery/power supply
Symptom Cause/remedy
The unit does not start. c The internal battery may be depleted. Connect
the AC power adapter and charge the battery
(page 14).
The unit turns on briefly, but
then turns off again.
c Even when the internal battery is fully charged,
it gradually loses charge if the unit is not used
for an extended period of time, which can lead
to reduced operating time. If you do not use the
unit for a while, fully charge it before using the
unit (page 14).
c When the unit is shipped, the internal battery is
not fully charged. It may therefore be empty by
the time you receive it.
c When using the unit on internal power at low
temperatures, usage time may be radically
reduced (page 14).
c The performance of the internal battery
gradually deteriorates, depending on the number
of times it is charged, usage time, and storage
period. Therefore, operating time may be
reduced even if the battery is fully charged. This
may mean that the battery needs to be replaced.
Contact your dealer or an authorized service
center regarding battery replacement.
The unit turns off unexpectedly. c When the unit is used stand-alone, it turns off
automatically after remaining idle for five minutes,
whether operating on internal power or through
the AC power adapter. Restart the unit (page 21).
When the unit is turned on,
there is no battery icon at the top
left corner of the LCD display.
c Connect the AC power adapter and fully charge
the battery (page 14).
