Precautions (Battery Pack)
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 hairpins 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 Use With Any Other Computer The battery pack is rechargeable and was intended for the specified computer or charger. Do not use it with a computer other than the one for which it was designed. Do Not Use This Computer with a Battery Pack Other Than the One Specified Use only the specified Panasonic battery pack (CF-VZSU29) with your CF-51. Use of batteries other than those manufactured and supplied by Panasonic may present a safety hazard. 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 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. 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

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 {32°F to 122°F}) ( Reference Manual �Battery Power�). 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.) If the temperature is low, the operating time is shortened. Only use the computer within the allowable temperature range. This computer has a high temperature 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 temperature 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.

Appendix Troubleshooting Useful Information Getting Started

Do Not Put into a Microwave Do not put the battery pack into a microwave 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. 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 pack to water, or allow it to become wet.
