If the battery empty alert is displayed and the power cannot be
turned on, charge the battery for a while.
While charging, the tablet may not turn on even when the
charging lamp is illuminated in red. Charge longer and try turning
power on again.
Frequently recharging the battery when its power is still
remaining enough may shorten the usable life of the internal
battery. It is recommended to use the battery to a certain level
(e.g. after the battery level decreases) before recharging.
When the battery becomes warm, charging may automatically
stop even if the battery has not been fully charged. Charging
automatically resumes after the temperature lowers to an
appropriate temperature.
If you watch Mobacas, receive contents, etc. while charging,
move the tablet as far away as possible from the power plug
section of the AC adapter.

Internal battery usable life
■
Internal battery is a consumable product. Battery life per charge
is gradually reduced every time the battery is charged.
When battery life per charge is reduced to about half of the
default time, this means that the internal battery is approaching
the end of its usable life. In this case, it is recommended to
replace the battery as soon as possible. For details on replacing
the internal battery, contact the number listed in "Repairs" (in
Japanese only) on the last page or a repair counter that
DOCOMO specifies.
If you watch TV etc. while charging for a long time, the usable life
of the internal battery may become shorter than estimated.
AC adapter and DC adapter
■
Refer to user's guide of AC Adapter 03/04 (sold separately) or
DC Adapter 03/04 (sold separately).
AC Adapter 03/04 covers from 100 to 240V AC.
The shape of the plug for the AC adapter is for 100V AC (for
domestic use). To use the AC adapter of 100 to 240V AC

of stay is required. Do not use a voltage converter for overseas
travel to charge the battery.
