Before Using the Handset
The battery pack is not fully charged at the time
of purchase. Be sure to charge the battery
before use.
It is recommended that the accompanying
wireless charger be used for charging to prevent
water from seeping or dust from getting in
caused by forgetting to close the external
connector terminal cover (
n
P. 35).
FOMA Charger microUSB Adapter SH01/FOMA
charging microUSB adapter T01 (sold
separately) is required to charge with FOMA AC
Adapter 01/02 (sold separately) or FOMA DC
Adapter 01/02 (sold separately).
Do not charge for a long time with the power left
on. If the handset is left on after charging is
complete, the battery pack charge decreases.
In that case, the AC or DC adapter (sold
separately) or the wireless charger charges the
battery again. However, depending on the time
when the handset is disconnected from the AC or
DC adapter or the wireless charger, 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 illumination 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 turn on
even when the charging illumination 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 life of
the battery pack. It is recommended to use the
battery to a certain level before recharging.
The following figures are estimated times for
charging an empty battery pack with the handset
turned off.
The charging illumination illuminates in red while
charging, and it turns off when charging is
completed.
If the power of the handset is off during the use
of the wireless charger, the charging illumination
flashes in red when charging starts. Also, the
charging illumination may flash before charging
finishes.
Check that the battery pack has been properly
attached when the charging illumination flashes
in red during the use of the AC or DC adapter.
The illumination also flashes in red when the
battery pack has reached the end of its service
life.
