This product is intended to be connected to analogue
networks and private switching systems in the United
Kingdom.
This equipment complies with the essential
requirements of the Radio Equipment and
Telecommunications Terminal Equipment Directive,
1999/5/E
Choosing a position
Your On-Air DECTf@x Plus should be kept clear of dust,
moisture, high temperature and vibration and should not be
exposed to direct sunlight. Don’t install it close to radiators or
air-conditioning outlets or in excessively warm, humid or dusty
places.
How many phones you can have
Your exchange line provides only a small current to make your
telephone ring. Although you may have any number of sockets it
is important to limit the number of telephones and other items of
apparatus connected to the line by these sockets. This ensures
that each telephone will receive enough current to ring.
Every telephone 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 the REN’s add up to no more than 4.
On-Air DECTf@x Plus has a REN of 1. Any telephone provided
by BT may be assumed to have a REN of 1 unless otherwise
stated on the base. Even where the number of telephones has
been limited, there is no guarantee that the different types of
telephone on the same line will ring.
Safety warnings
How to connect the mains lead to a plug
Your apparatus comes complete with fitted plug. If however, it
becomes necessary to fit an alternative mains plug, the following
instructions must be adhered to.
Read the instruction carefully before connecting the mains lead
to a plug. If in doubt, consult a qualified electrician.
As the colours of the wires in the mains lead of the apparatus
may not correspond with the coloured markings identifying the
terminals in your plug, proceed as follows:
The wire which is coloured blue must be connected to the
terminal which is marked with the letter N or coloured black.
The wire which is coloured brown must be connected to the
terminal which is marked with the letter L or coloured red.
