Battery care
The device is powered by a battery. It is necessary to charge the battery when it is empty.
You can achieve a maximum performance of a new battery only by charging it when it is
fully discharged.
If you do not use the charger, unplug it from the power outlet and from the device. Do
not leave a fully charged battery charge for longer than is strictly necessary. Overcharging
may shorten its life.
Temperature affects the level to which the battery can be recharged. Therefore, it is
necessary to keep the battery at room temperature before charging. If the temperature of
the battery exceeds 40 °C, it is not possible to charge it.

charged.

local regulations.
