3. Charging

It takes approximately 3 1/2 hours to charge the handset from fully discharged to its full capacity. Place the hand­set in the charger. When the handset is turned on, the display shows the charging status in line 3. For correct

charging the room temperature has to be between 0°C and 25°C and the handset must therefore not be placed in
direct sunshine. The battery has a built-in heat sensor which will stop charging if the battery temperature is too high.

It is necessary to recharge the battery when the display shows “BATTERY LOW”, or if it can not be turned on. The
LED flashes at a low frequency while charging and lights constantly when the charging is finished. The display
goes back to normal mode when fully charged.

When the handset is placed in the charger it will not vibrate, and B-answer is inactive. If the battery is fully dis­charged, up to 10 min. may pass before charging begins and the handset can be turned on. When charging
begins the charging status is shown in the 3rd line of the display and the LED flashes slowly.
