Care should be exercised with regard to the following in order to avoid the possibility of
liquid leakage, overheating, or bursting.
• Do not throw the battery pack into a fire or expose it to heat.
• Do not place the battery pack together with articles such as necklaces or hairpins when
carrying or storing.
• Do not insert sharp objects into the battery pack, expose it to bumps or shocks, deform,
disassemble, or modify it.
• Do not short the positive (+) and negative (-) contacts.
• The battery pack is a rechargeable battery intended for use with the CF-35 series or the
specified charger (CF-VCB251A). Do not use it with a computer other than the one for
which it was designed.
• 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 an automobile on a sunny day, for example), or in a
cold place.
Do not touch the terminals on the battery pack. The battery pack may no longer function
properly if the contacts are dirty or damaged.
Do not expose the battery to water, or allow it to become wet.
Do not put the battery into a microwave oven or a pressurized chamber.
This computer prevents overcharging of the battery by recharging only when the remain-
ing power is less than approx. 95% of capacity.
If the battery should leak and some of the fluid get into your eyes, do not rub your eyes.
Immediately flush eyes with clear water and see a doctor for medical treatment as soon as
possible.
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 unit or
charger and discontinue use.
If the battery pack will not be used for a long period of time (a month or more), charge the
battery pack until the remaining battery become 30% to 40% and store it in a cool, dry
place.
Using the Battery Pack
Precautions
NOTE
The battery pack may become warm during recharging or normal use. This is com-
pletely normal.
Recharging will not commence outside of the allowable temperature range (5 °C to 35
°C (41°F to 95 °F)). To allow the battery to charge, adjustments have to be made to the
temperature. Once the allowable range requirement is satisfied, charging begins auto-
matically. Note that the recharging time varies based on the usage conditions.
If the temperature is low, the operating time is shortened. Therefore, please use the
computer within the allowable temperature range.
Although the battery has not begun to run down, the battery indicator may light up red
or emit a beep. This indicates a significant rise in the temperature of the battery pack.
This is typically caused by the fact that the battery pack has been delivering a high level
of power because the computer has been used with the display at the brightest setting
and with the power-saving function off. In order to protect the battery pack from tem-
perature rises, the computer's processing speed is automatically reduced and the battery
temperature is brought down. It is also a good idea to connect the AC adapter, set the
power-saving function, and turn down the brightness of the display. When the tempera-
ture has dropped, the computer's regular processing speed will be restored.
