Before Using the Terminal
･
The internal battery is a consumable
accessory. The usage duration of the battery
per one charge decreases gradually each time
the battery is recharged.
･
When the usage duration per one charge
becomes about half of a new battery, the life
of the internal battery is assumed to be
almost over.
･
Watching 1Seg etc. for a long time while
charging may shorten the lifetime of the
internal battery.

To check internal battery performance, from
the Home screen, tap and tap

The AC Adapter 04 (optional) is compatible
with AC 100 V to 240 V. For using the terminal
overseas, a plug adapter that fits the electrical
outlets in the country you stay is needed. Do
not use an electrical transformer for overseas
use to charge the terminal.

Use a compatible AC adapter or microUSB
cable for charging (P.250). If you use a charger
other than the compatible one, charging may
not be available or operations may not be

Insert and remove the AC adapter cable or
microUSB cable slowly and evenly so that
excessive force is not applied.

When you start charging with the terminal
powered off, the power turns on. However,
