Environment
Your Synergy Handset should be kept free of dust,
moisture, high temperature, vibration and should not
be exposed to direct sunlight. Do not stand it on
carpets or other surfaces which generate fibres or place
it in locations which prevent the free flow of air over
its surfaces.
If the power fails
This equipment is not designed for making emergency
calls when the power fails. Alternative arrangements
should be made for access to emergency services.
How many phones can you have?
All items of telephone equipment have a Ringer
Equivalence Number (REN), which is used to calculate
the number of items that may be connected to any one
telephone line. The Synergy base station has a REN of 1.
Additional Handsets have a REN value of 0. Any other
instrument provided by BT may be assumed to have a
REN of 1 unless stated otherwise. A total REN of 4 is
allowed.
Warning
The apparatus is only designed to be operated in a normal
office or domestic environment where the relative humidity
does not exceed 75%. It should not be used in bathrooms or
