However, all approved cordless phones use
radio to communicate between the base and
cordless handset units. It is therefore possible
that your conversations could be overheard
by other people, on their cordless phones, or
on ordinary radios that use the same radio
frequencies.
As this problem applies equally to all similar
cordless phones currently available in the UK,
call privacy cannot be guaranteed. However,
the security coding prevents unauthorised use
of your line.
You may find that your Freestyle 80 Plus
picks up conversations from other cordless
phones being used nearby. If you get this type
of interference try changing channels using

Ringer Equivalence Number (REN)
Although you may have any number of
sockets, it it 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 RENs add up to no more
than 4.
Freestyle 80 Plus has a REN of 1. Any
telephone provided by BT may be assumed to
have a REN of 1 unless otherwise stated on
