Charging the headset

Always store the headset in the base station to ensure that it is fully
charged when needed. The intelligent battery charging technology pre-
vents over-charging.

Place the headset into the magnetic holder of the base station.
The Headset LED lights up blue and the rechargeable battery is being
charged. The Charge status LED on the base station indicates the
charge status:

Shortly before the rechargeable battery is about to run flat, only one LED
segment lights up weakly. The Headset LED flashes red and you hear three
beeps. You have several minutes of battery reserve. When the recharge-
able battery is flat, the headset switches off.
If the headset is outside the range of the base station, it will switch
off after 30 minutes in order to conserve battery power.
