Charging battery

When charging the battery for the first time, it is necessary to leave the handset in the charger for 14-16 hours for the battery to be fully charged.

During normal operation, it takes approximately 3.5 hours to charge the handset from fully discharged to its full capacity.

• Place the handset in the charger.

For correct charging, be sure the room temperature is between 0°C and 25°C. Do not place the handset in direct sunlight. The battery has a built-in heat sensor which will stop charging if the battery temperature is too high.
