Transmission frequencies

This cordless telephone has been
designed to operate on radio
frequencies which have been
assigned to the exclusive use of
cordless telephones. As the use of
cordless telephones becomes more
widespread, the quality of service
obtained from this apparatus may
lessen.

Ringer Equivalence Number (REN)

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 those
sockets, to ensure that each
telephone will 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.

Freestyle 90 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 unit.
Even where the number of
telephones has been limited, there
is no guarantee that different types
of telephone on the same line will
ring.
