4. If you wear a hearing aid, please note that the Synergy 
system works by sending radio signals between the base 
station and handset. These signals can interfer e with 
hearing aids, causing a humming noise.
5. The Synergy telephone system can interfere with other 
electrical equipment, e.g. answering machines, TV and 
radio sets, clock radio/alarms and computers if placed 
too close. It is recommended that you place your Synergy 
Charger Unit/Base Station at least one metre away from 
such appliances to avoid any risk of interference.
6. The Synergy Handset and Charger can become warm 
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.
