Terminal operation
■
Become hot while operating/charging.
While calling, depending on the radio
･
wave condition or call duration time, the
terminal may become hot around the
earpiece/speaker. This condition is not
abnormal.
While operating or charging, or if you
･
watch TV, record video, etc. for a long time
while charging the battery, the terminal,
internal battery or adapter may become
hot. There is no problem about operation
and continue to use it.
The operation time provided by the
battery is short.
Is the terminal left for a long time under
･
the state of out of service area?
Out of service area, a lot of power is
consumed to search available radio
waves.
The operating time of the battery varies
･
depending on the operating
environment and the degradation level of
the internal battery.
The internal battery is a consumable part.
･
Each time it is charged, time available with
each charging reduces.
If the operation time becomes too short
with fully charged state, contact "Repairs"
on the last page (in Japanese only) or a
DOCOMO-specified repair office.
