limit your ability to use the same content on your device again. For more information, contact your service provider.

in the device.

Battery safety
Always switch the device off and disconnect the charger before removing the battery. When you unplug a charger or an
accessory, hold and pull the plug, not the cord.
When your charger is not in use, unplug it from the electrical plug and the device. Do not leave a fully charged battery connected
to a charger, as overcharging may shorten the battery’s lifetime. If left unused, a fully charged battery will lose its charge over
time.
Always 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.
Accidental short-circuiting can happen when a metallic object touches the metal strips on the battery, for example, if you carry
a spare battery in your pocket. Short-circuiting may damage the battery or the connecting object.
Do not dispose of batteries in a fire as they may explode. Dispose of batteries according to local regulations. Recycle when
possible. Do not dispose as household garbage.
Do not dismantle, cut, open, crush, bend, puncture, or shred cells or batteries. If a battery leaks, do not let battery liquid touch
skin or eyes. If this happens, immediately flush the affected areas with water, or seek medical help.
Do not modify, remanufacture, attempt to insert foreign objects into the battery, or immerse or expose it to water or other
liquids. Batteries may explode if damaged.
Use the battery and charger for their intended purposes only. Improper use, or use of unapproved batteries or chargers may
present a risk of fire, explosion, or other hazard, and may invalidate any approval or warranty. If you believe the battery or
charger is damaged, take it to a service center for inspection before continuing to use it. Never use a damaged battery or
charger. Only use the charger indoors.
