Handling the Battery Pack
The battery pack is consumable.
Battery life varies depending on usage
conditions, etc., but it is time to change
battery packs when the usage time has
become extremely short even though the
battery pack has been fully recharged.
In this case, please purchase a new battery
pack.
The ambient temperature of the room
should be 5
˚
C to 35
˚
C.
The available operating time of the
battery pack depends on the conditions
of usage and battery pack.
Depending on the usage condition, the
battery pack may inflate slightly when
the battery life is almost over. This is not
a malfunction.
Do not store the battery pack in the
following cases:
• The battery is fully charged (immediately
after the charging is complete)
• The battery has run out (the phone cannot
power on)
The performance and life of the battery pack
may deteriorate.
It is recommended that you store the battery
pack with around 40% battery level.
Handling the Adapter (including
Charger Adapter)
The ambient temperature of the room
should be 5
˚
C to 35
˚
C.
Do not charge the battery pack:
• In a humid, dusty or unstable place
• Near a land-line phone, TV or radio
It is normal that the adapter (including
charger adapter) become warm while
charging. Keep using it.
Do not use the DC adapter to charge the
battery when the car engine is not
running.
Doing so may drain the car battery.
If you use an electrical outlet with an
unplugging-protection mechanism, follow
the instructions of the manual for the
outlet.
Do not expose the adapter to strong
shocks. Do not deform the charging
terminal.
Doing so may cause malfunction.
Handling the UIM
Do not apply excessive force to the UIM
when attaching/removing it.
Note that the warranty does not cover
damage caused by inserting the UIM into
another type of IC card reader or writer.
Always keep the IC part clean.
Wipe with a soft, dry cloth (such as an
eyeglass cleaning cloth).
