Battery Power

P r e c a u t i o n s

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-25 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 remaining power is less than approx. 95% of capacity.

Should the battery leak and some of the fluid gets 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.

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 level becomes 30% to 50% and store it in a cool, dry place.

N O T E

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 (0 °C to 35 °C (32°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 automati- cally. Note that the recharging time varies based on the usage conditions. (Recharging takes longer than usual when the temperature is 10 °C (48 °F) or less.)

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, connect the AC adapter, set the power-saving function, and turn down the brightness of the display. If power discharge continues for 5 minutes or more while the battery pack's temperature remains high, the computer automatically turns itself off. When disabling the speaker using [System Setup] in the Setup Utility, the battery low warning beep is also disabled.
