Precautions (Battery Pack)
z
Care should be exercised with regard to the following
in order to avoid the possibility of overheating, fire or
damage.
Avoid Heat
Do not throw the battery pack into a fire or
expose it to excessive heat.
Keep Articles Away
Do not place the battery pack together
with articles such as necklaces or hair-
pins when carrying or storing.
Do Not Disassemble
Do not insert sharp objects into the battery
pack, expose it to bumps or shocks,
deform, disassemble, or modify it.
Do Not Short
Do not short the positive (+) and negative
(-) contacts.
Avoid Extreme Heat, Cold and Direct
Sunlight
Do not charge, use or leave the battery
pack for extended periods where it will be
exposed to direct sunlight, in a hot place
(in a car on a sunny day, for example), or
in a cold place.
Do not charge the battery using the
methods other than indicated in this
manual
Do not use this computer with a bat-
tery pack other than the one specified
(the one included with the computer or
the specified battery pack sold sepa-
rately)
Do Not Use With Any Other Computer
The battery pack is rechargeable and
was intended for the specified computer.
Do not use it with a computer other than
the one for which it was designed.
Do Not Put into a Microwave
Do not put the battery pack into a micro-
wave oven or a pressurized chamber.
Stop Using
Should the battery emit an abnormal
odor, become hot to the touch, become
discolored, change shape, or become in
any way different from normal, remove it
from the computer and stop using it.
z
Do not touch the terminals on the battery pack. The
battery pack may no longer function properly if the
contacts are dirty or damaged.
z
Do not expose the battery pack to water, or allow it to
become wet.
z
If the battery pack will not be used for a long period of
time (a month or more), charge or discharge (use) the
battery pack until the remaining battery level becomes
30% to 40% and store it in a cool, dry place.
z
This computer prevents overcharging of the battery by
recharging only when the remaining power is less than
approx. 95% (when Economy Mode (ECO) is enabled:
75%) of capacity.
z
The battery pack is not charged when the computer is
first purchased. Be sure to charge it before using it for
the first time. When the AC adaptor is connected to
the computer, charging begins automatically.
z
Should the battery leak and the fluid get into your
eyes, do not rub your eyes. Immediately flush your
eyes with clear water and see a doctor for medical
treatment as soon as possible.
NOTE
z
The battery pack may become warm during
recharging or normal use. This is completely nor-
mal.
z
Recharging will not commence if internal tempera-
ture of the battery pack is outside of the allowable
temperature range (0 °C to 55 °C {32 °F to 131
°F}). (
Î
"Battery Power" in onscreen Reference
Manual) Once the allowable range requirement is
satisfied, charging begins automatically. Note that
the recharging time varies based on the usage
conditions. (Recharging takes longer than usual
when the temperature is 10 °C {50 °F} or below.)
z
If the temperature is low, the operating time is
shortened. Only use the computer within the
allowable temperature range.
z
The battery pack is a consumable item. If the
amount of time the computer can be run by using a
particular battery pack becomes dramatically
shorter and repeated recharging does not restore
its performance, the battery pack should be
replaced with a new one.
z
When transporting a spare battery inside a pack-
age, briefcase, etc., it is recommended that it be
placed in a plastic bag so that its contacts are pro-
tected.
z
Always power off the computer when it is not in
use. Leaving the computer on when the AC adap-
tor is not connected will exhaust the remaining bat-
tery capacity.
