Handling the Battery Pack
c
The battery pack is a consumable item.
The operating time of the fully charged battery
pack depends on the conditions under which
you use it, but if it decreases significantly, it is
time to exchange it. Exchange it for a new
battery pack with the same specifications.
c
Charge the battery pack within the
proper ambient temperature range (5°C
to 35°C).
c
Make sure to charge the battery the first
time you use the FOMA terminal or if you
have not used it for a long period.
c
The operating time of the battery pack
depends on the conditions under which
you use it and the deterioration level of
the battery pack.
c
Depending on the conditions under
which it is used, the battery pack may
swell as the life comes close to the end,
but this causes no problem.
c
Leaving the metallic part (connector)
soiled may cause poor contact and the
FOMA terminal may switch off. Wipe off
the dirt with a dry cloth or cotton swab
before use.
c
Do not store or leave the battery pack
with no battery left.
Failure to observe this instruction may lower
the performance or shorten the life of the
battery pack.
If you leave it for a long period, remove it from
the FOMA terminal, and store it in a cool, dry
place. Also, charge the battery at least once in
half a year.
c
Keep the battery pack in a cool and dry
place away from direct sunlight.
If you do not use the battery pack for a long
period, use up the battery, remove the pack
from the FOMA terminal, and keep it in a plastic
bag.
Handling the Adapters and Charger
c
Charge the battery pack within the
proper ambient temperature range (5°C
to 35°C).
c
Do not charge the battery:
a
In a humid, dusty or shaky place
a
Near your landline, TV or radio
c
The adapter or charger may become
warm while the FOMA terminal is
charged. This is normal, and you can
continue to use it.
c
Do not use the DC Adapter while the
engine is not running.
Doing so may drain the car battery.
c
If you use an outlet that provides pull-
out prevention, follow the instructions of
the outlet manual.
c
Do not subject the adapter or charger to
strong impacts. Do not deform the
charging terminal or terminal guide.
Doing so may cause malfunction.
