Before using the handset
The battery pack is not fully charged at the time of purchase. Be sure to charge the battery using the exclusive AC adapter and microUSB cable SH10 before
use.
/ Cautions while charging
Do not charge for a long time with the power left on. If the phone is left on after charging is complete, the battery pack charge decreases.
In that case, the AC adapter charges the battery again. However, depending on the time when the phone is disconnected from the AC adapter, the battery charge level
may be low or the battery may only be usable for a short time.
If the phone is left for a long time even after the charging is completed, the battery level may decrease.
When the battery is empty and the phone is recharging, charging lamp may not illuminate immediately.
If the battery empty alert is displayed and the power cannot be turned on, charge the battery for a while.
While charging, the phone may not turn on even when charging lamp is illuminated in red. Charge longer and try turning power on again.
Frequently recharging the battery while there is a reasonable charge remaining may shorten the life of the battery pack. It is recommended that the battery be reduced
to a minimum level before recharging.
/ Lamp display
Charging lamp illuminates in red while charging, and it turns off when charging is completed.
Check that the battery pack has been properly attached when charging lamp flashes red. The lamp also flashes red when the battery pack has reached the end of its
service life.
The battery pack can also be charged with the phone turned on (While charging, the battery icon appears with [w] superimposed).
When the battery becomes warm, charging may automatically stop even if the battery has not been fully charged. Charging resumes after the temperature lowers to an
appropriate temperature.
/ Battery pack service life
Battery pack is a consumable product. Service time per charge is gradually reduced every time the battery is charged.
When service time per charge is reduced to about half of the default time, this means that the battery pack is approaching the end of its service life. In such a case, it
is recommended to replace the battery pack as soon as possible. Depending on usage, the battery pack may swell as it approaches the end of its service life, but this
will not cause problems.
If you operate the phone while charging for a long time, the service life of the battery pack may become shorter than estimated.
