Battery Information
Do not attempt to replace the battery by yourself as it is built-in and cannot be changed.
Do not dismantle the charger as it may expose you to dangerous voltages or other
hazards.
Please charge the device only with compatible chargers.
Incorrectly reassembling the device can cause electric shock when it is used again.
Do not use the charger outdoors or in a humid environment.
Avoid charging the device in extremely high or low temperatures.
Leaving the battery in hot or cold places, such as in a closed car during the summer or winter,
will reduce the capacity and lifetime of the battery and its ability to charge. 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 for a while, even when the battery is fully charged. Battery performance is particularly
limited in temperatures well below freezing.
