z
If performing functionality like talking on the phone,
doing communications - data, packet, etc. - for long
hours while charging, the temperature of the FOMA
terminal may rise to turn the illumination lamp off. If that
happens, wait until the temperature of the FOMA
terminal falls below normal, and then start charging
again.

starting to charge
z
Sometimes when the temperature of the FOMA

If that happens, wait until the temperature of the FOMA
terminal falls below normal, and then start charging
again.
Battery life is short
z
Isn’t your FOMA terminal left in a state of Out of Area
for long hours? The FOMA terminal, when in a state of
Out of Area, searches for available radio waves, which
consumes much of the battery pack power.
z
The lifespan of a battery pack may be shortened
depending on usage environment and how it has
deteriorated. → P.46
z
Battery packs are consumable items. The amount of
usable time decreases every time a rechargeable
battery pack is recharged.
When you find that your original battery pack lasts
shorter than regular batteries, then exchange it for a
specified new battery pack. → P.46
The battery pack gets quite warm while charging
it or while it is operating

FOMA terminal, battery pack or adapter (including the
charger) may rise. There is no need to worry about
safety (since the products are designed to meet the
Safety Standards), which allows you to continue to use
them.
