Safety instructions ixGuidelines for safe battery usageThis computer uses a Lithium-ion battery. Do not use it in a humid, wet orcorrosive environment. Do not put, store or leave your product in or near a heatsource, in a high temperature location, in strong direct sunlight, in a microwaveoven or in a pressurized container, and do not expose it to temperatures over60° C (140° F). Failure to follow these guidelines may cause the battery to leakacid, become hot, explode or ignite and cause injury and/or damage. Do notpierce, open or disassemble the battery. If the battery leaks and you come intocontact with the leaked fluids, rinse thoroughly with water and seek medicalattention immediately. For safety reasons, and to prolong the lifetime of thebattery, charging will not occur at temperatures below 0° C (32° F) or above40° C (104° F).The full performance of a new battery is achieved only after two or threecomplete charge and discharge cycles. The battery can be charged anddischarged hundreds of times, but it will eventually wear out. When theoperation time becomes noticeably shorter than normal, buy a new battery.Use only the approved batteries, and recharge your battery only with theapproved chargers designated for this device.Use the battery only for its intended purpose. Never use any charger or batterythat is damaged. Do not short-circuit the battery. Accidental short-circuiting canoccur when a metallic object such as a coin, clip or pen causes direct connectionof the positive (+) and negative (-) terminals of the battery. (These look likemetal strips on the battery.) This might happen, for example, when you carry aspare battery in your pocket or purse. Short-circuiting the terminals maydamage the battery or the connecting object.The capacity and lifetime of the battery will be reduced if the battery is left inhot or cold places, such as in a closed car in summer or winter. Always try tokeep the battery between 15° C and 25° C (59° F and 77° F). A device with a hotor cold battery may not work temporarily, even when the battery is fullycharged. Battery performance is especially limited in temperatures well belowfreezing.Do not dispose of batteries in a fire as they may explode. Batteries may alsoexplode if damaged. Dispose of batteries according to local regulations. Pleaserecycle when possible. Do not dispose as household waste.Wireless devices may be susceptible to interference from the battery, whichcould affect performance.Replacing the battery packThe computer uses Lithium-ion batteries. Replace the battery with the sametype as that which came bundled with your product. Use of another batterymay present a risk of fire or explosion.
