Read Me First
Do not expose the battery pack to
water, or allow it to become wet.
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.
This computer prevents overcharging
of the battery by recharging only
when the remaining power is less
than approx. 95% of capacity.
The battery pack is not charged when
the computer is fi rst purchased. Be
sure to charge it before using it for the
fi rst time. When the AC adaptor is
connected to the computer, charging
begins automatically.
Should the battery leak and the fl uid
get into your eyes, do not rub your
eyes. Immediately fl ush your eyes
with clear water and see a doctor for
medical treatment as soon as pos-
sible.
NOTE
The battery pack may become
warm during recharging or normal
use. This is completely normal.
Recharging will not commence if
internal temperature of the battery
pack is outside of the allowable
temperature range (0 °C to 50 °C).
( Reference Manual "Battery
Power") Once the allowable range
requirement is satisfi ed, 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 or below.)

In high-temperature environments,
the battery takes longer to fully
recharge and the operating time is
shorter. Only use the computer
within the allowable temperature
range.
This computer has a high tempera-
ture mode function that prevents the
degradation of the battery in high
temperature environments. (
Reference Manual "Battery Power")
A level corresponding to a 100%
charge for high temperature mode
is approximately equivalent to an
80% charge level for normal tem-
perature mode.
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.
When transporting a spare battery
inside a package, briefcase, etc., it
is recommended that it be placed in
a plastic bag so that its contacts are
protected.
Always power off the computer
when it is not in use. Leaving the
computer on when the AC adaptor
is not connected will exhaust the
remaining battery capacity.
