Battery information<br />

Your device is powered by a rechargeable battery. The battery can be charged and discharged hundreds of times, but it will<br />

eventually wear out. When the talk and standby times are noticeably shorter than normal, replace the battery. Use only <strong>Nokia</strong><br />

approved batteries, and recharge your battery only with <strong>Nokia</strong> approved chargers designated for this device.<br />

If a replacement battery is being used for the first time or if the battery has not been used for a prolonged period, it may be<br />

necessary to connect the charger, then disconnect and reconnect it to begin charging the battery.<br />

Unplug the charger from the electrical plug and the device when not in use. Do not leave a fully charged battery connected to<br />

a charger, since overcharging may shorten its lifetime. If left unused, a fully charged battery will lose its charge over time.<br />

If the battery is completely discharged, it may take several minutes before the charging indicator appears on the display or<br />

before any calls can be made.<br />

Use the battery only for its intended purpose. Never use any charger or battery that is damaged.<br />

Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object such as a coin, clip, or pen causes<br />

direct connection of the positive (+) and negative (-) terminals of the battery. (These look like metal strips on the battery.) This<br />

might happen, for example, when you carry a spare battery in your pocket or purse. Short-circuiting the terminals may damage<br />

the battery or the connecting object.<br />

Leaving the battery in hot or cold places, such as in a closed car in summer or winter conditions, will reduce the capacity and<br />

lifetime of the battery. Always try to keep the battery between 15°C and 25°C (59°F and 77°F). A device with a hot or cold battery<br />

may not work temporarily, even when the battery is fully charged. Battery performance is particularly limited in temperatures<br />

well below freezing.<br />

Do not dispose of batteries in a fire as they may explode. Batteries may also explode if damaged. Dispose of batteries according<br />

to local regulations. Please recycle when possible. Do not dispose as household waste.<br />

Do not dismantle or shred cells or batteries. In the event of a battery leak, do not allow the liquid to come in contact with the<br />

skin or eyes. In the event of such a leak, flush your skin or eyes immediately with water, or seek medical help.<br />
