Before Using the Handset

[16/30]
The internal battery is not fully charged at the time of
purchase. Be sure to charge the battery before use.
■ Cautions while charging
For details on the estimated charge time nP. 95 “Main
specifications”
The battery can also be charged with the handset turned on
(While charging, the battery icon appears with [w]
superimposed).
Do not charge for a long time with the power left turned on. If the
handset is left turned on after charging is complete, the internal
battery charge level decreases.
In this case, an AC or DC adapter (sold separately) charges the
battery again. However, depending on the time when the
handset is disconnected from the AC or DC adapter, the battery
charge level may be low or the battery may only be usable for a
short time.
If the handset is left for a long time even after the charging is
completed, the battery level may decrease.
When the battery is empty and the handset is being charged, the
charging lamp may not illuminate immediately. However,
charging is in progress.
If the battery empty alert is displayed and the power cannot be
turned on, charge the battery for a while.
While charging, the handset may not be turned on even when the
charging lamp is illuminated in red. Charge longer and try turning
the 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.
■ Estimated battery life when fully charged
For details on the battery life nP. 95 “Main specifications”
■ 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 approximately 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 05 (sold separately) or DC
Adapter 04 (sold separately).
AC Adapter 05 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
overseas, a conversion plug adapter applicable to your country
of stay is required. Do not use a voltage converter for overseas
travel to charge the battery.
Do not allow the docomo nano UIM card or tray to fall when
removing them.
Make sure not to touch or damage the IC (gold) of the docomo
nano UIM card when handling it. Also, note that inserting or
removing the docomo nano UIM card forcibly may damage it or
deform the tray.
Refer to the docomo nano UIM card user's guide for more
information on the docomo nano UIM card.
Do not misplace the docomo nano UIM card once it is removed.
IMEI plate
A plate on which the IMEI number (International Mobile
Equipment Identifier) is printed is stowed near the microSD
Card slot. The IMEI number is required when you contact a
repair counter that DOCOMO specifies, so do not pull it out.
Note that pulling out the IMEI plate forcibly or adding forces on
it may damage the plate.
If you accidentally pull out the IMEI plate, slowly return the IMEI
plate to the original position while taking care not to insert it too
deep.
