Health and Safety Information 142• If you use the device near the network's base station, it uses lesspower; talk and standby time are greatly affected by the signalstrength on the cellular network and the parameters set by thenetwork operator.• Follow battery usage, storage and charging guidelines found in theuser’s guide.• Battery charging time depends on the remaining battery charge andthe type of battery and charger used. The battery can be charged anddischarged hundreds of times, but it will gradually wear out. When theoperation time (talk time and standby time) is noticeably shorter thannormal, it is time to buy a new battery.• If left unused, a fully charged battery will discharge itself over time.• Use only Samsung-approved batteries and recharge your battery onlywith Samsung-approved chargers. When a charger is not in use,disconnect it from the power source. Do not leave the batteryconnected to a charger for more than a week, since overcharging mayshorten its life.• Do not use incompatible cell device batteries and chargers. Some Websites and second-hand dealers, not associated with reputablemanufacturers and carriers, might be selling incompatible or evencounterfeit batteries and chargers. Consumers should purchasemanufacturer or carrier recommended products and accessories. Ifunsure about whether a replacement battery or charger is compatible,contact the manufacturer of the battery or charger.• Misuse or use of incompatible devices, batteries, and charging devicescould result in damage to the equipment and a possible risk of fire,explosion, leakage, or other serious hazard.• Extreme temperatures will affect the charging capacity of your battery:it may require cooling or warming first.• Do not leave the battery in hot or cold places, such as in a car insummer or winter conditions, as you will reduce the capacity andlifetime of the battery. Always try to keep the battery at roomtemperature. A device with a hot or cold battery may temporarily notwork, even when the battery is fully charged. Li-ion batteries areparticularly affected by temperatures below 0 °C (32 °F).• Do not place the device in areas that may get very hot, such as on ornear a cooking surface, cooking appliance, iron, or radiator.• Do not get your device or battery wet. Even though they will dry andappear to operate normally, the circuitry could slowly corrode andpose a safety hazard.• Do not short-circuit the battery. Accidental short-circuiting can occurwhen a metallic object (coin, clip or pen) causes a direct connectionbetween the + and - terminals of the battery (metal strips on thebattery), for example when you carry a spare battery in a pocket orbag. Short-circuiting the terminals may damage the battery or theobject causing the short-circuiting.• Do not permit a battery out of the device to come in contact with metalobjects, such as coins, keys or jewelry.SWD-M100.book Page 142 Monday, March 8, 2010 8:09 AM
