Unplug the charger from the electrical plug and the device when not in use. Do

not leave a 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.

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.

Use the battery only for its intended purpose. Never use any charger or battery

that is damaged.

Do not short-circuit the battery. 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.

Leaving the battery in hot or cold places, such as in a closed car in summer or

winter conditions, will reduce the capacity and 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 may not work temporarily, even when the battery is fully

charged. Battery performance is particularly limited in temperatures well

below freezing.

Do not dispose of batteries in a fire as they may explode. Batteries may also

explode if damaged. Dispose of batteries according to local regulations. Please

recycle when possible. Do not dispose as household waste.

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 skin or eyes. In the event of

such a leak, flush your skin or eyes immediately with water, or seek medical

help.
