during charging.
The Synergy Handset has a range from the base station of
up to 300 metres outdoors and up to 50 metres indoors. It is
possible that the range may be affected by being near water
(e.g. large ponds, lakes, the sea) and large metal objects
(e.g. radiators, steel girders and metal partition walls.
