Fujitsu F-02F Instruction Manual page 32

The following conditions will lead to a charging error and
the indicator LED turns off. Charging restarts when the
charging becomes possible.
- When the power voltage of the charger becomes out of
chargeable range
- When temperature of the internal battery or the terminal
becomes out of chargeable range
* When the terminal gets hot, wait until it cools down and then retry
charging.
If charging takes a very long time, charging error is notified
and the indicator LED turns off. Remove the terminal from
the charger and retry.
When power voltage of the internal battery is abnormal,
charging error occurs and the indicator LED flashes. Remove
the terminal from the charger and retry in the correct
method. Even if you perform above operations but the
terminal is not charged correctly, remove the terminal from
the charger, turn the power OFF, and then contact "Repairs"
on the last page of this manual (in Japanese only) or
DOCOMO-specified repair office.
When charging starts with the battery empty, the terminal
may not be immediately activated after turning the power
ON. In this case, charge the terminal for a while with the
power OFF, and turn it ON.
For charging time, see "Main specifications" P174
❖
Internal battery life
The internal battery is a consumable part. Each time it is
charged, time available with each charging reduces.
Performing communication for a long time while charging
* may reduce the internal battery lifetime.
You can check performance (charging ability) of the internal
battery from "About tablet". P140
When a time available with each charging is reduced to
about a half from that of a new battery, replacement of the
internal battery is recommended because it is near the end
of life. For replacement of internal battery, contact "Repairs"
on the last page of this manual (in Japanese only) or
DOCOMO-specified repair office.
