only with Nokia approved chargers designated for this device. Use only
replacement batteries qualified with the device per the IEEE 1725-2006 standard.
Use of other batteries or chargers may present a risk of fire, explosion, leakage, or
other hazard.
If a battery is being used for the first time or if the battery has not been used for a
prolonged period, it may be necessary to connect the charger, then disconnect and
reconnect it to begin charging the battery. If the battery is completely discharged,
it may take several minutes before the charging indicator appears on the display or
before any calls can be made.
Safe removal. Always switch the device off and disconnect the charger before
removing the battery.
Unplug the charger from the electrical plug and the device when not in use. Do not
leave fully charged battery connected to a charger, since overcharging may shorten
its lifetime. If left unused, a fully charged battery will lose its charge over time.
Avoid extreme temperatures. Always try to keep the battery between 15°C and
25°C (59°F and 77°F). Extreme temperatures reduce the capacity and lifetime of
the battery. A device with a hot or cold battery may not work temporarily. Battery
performance is particularly limited in temperatures well below freezing.
Do not short-circuit. Accidental short-circuiting can occur when a metallic object
such as a coin, clip, or pen causes direct connection of the positive (+) and negative
(-) terminals of the battery. (These look like metal strips on the battery.) This might
happen, for example, when you carry a spare battery in your pocket or purse. Short-
circuiting the terminals may damage the battery or the connecting object.
Disposal. Do not dispose of batteries in a fire as they may explode. Dispose of
batteries according to local regulations. Please recycle when possible. Do not
dispose as household waste.
