Technical information
Choosing a position
Your Phone 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.
Wa r n in g
The apparatus is designed to be operated only in
a normal office or domestic environment where
the relative humidity does not exceed 60%. It
should not be used in bathrooms or near water.
Connecting to the UK network
Your Phone is tested and approved for connection
to the UK network, provided it is used in
accordance with the guidelines in this booklet.
How many phones can you have?
Although you may have any number of sockets, it
is important to limit the number of phones and
other items of apparatus connected to the line by
those sockets, to make sure that each phone will
ring.
Every phone or item of apparatus has a Ringer
Equivalence Number (REN). In most cases a
standard line should provide enough current for
two or more telephones or items of apparatus, if
there are no more than 4 RENs.
Your Phone has an REN of 1. Any phone provided
by BT has an REN of 1 unless it says otherwise
on the base. Even where the number of telephones
has been limited, there is no guarantee that the
different types of phone on the same line will ring.
If the REN is more than 4, the phone may not
ring. With different phone types a phone may still
not ring, even when the REN is less than 4.
You must not connect more than 4 Caller Display
products to one line.
