The FOMA terminal, battery pack, or adapter may become hot during operations or charging,
or if you use the camera function or view/record 1Seg for a long time while charging. This is
not a safety hazard, so you can continue to use them.
If you use the camera function or view/record 1Seg for a long time, the FOMA terminal may
become hot and the camera function or 1Seg may end. Wait a while before restarting to use
the camera function or 1Seg.
Battery usage time is short.
Has the FOMA terminal been out of the network service area for a long time?

of the network service area, more electricity is consumed than usual.
The battery pack usage time varies depending on the usage conditions and the degradation
level.→P.29
The battery pack is a consumable. The available usage time shortens every time the battery
pack is recharged.
If the usage time significantly reduces compared to the time of purchase even if the battery
pack is fully charged, purchase the specified battery pack.→P.29
