frequencies which have been assigned to the exclusive use of
cordless telephones. As the use of cordless telephones becomes
more widespread, users may experience a reduction in the quality
of service obtained from this apparatus.

Handset batteries
When fully charged and in good condition, the handset
batteries will last for up to 5 hours in Talk mode or 48 hours
in Standby mode.
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 RENs add up to no more than 4.
Freestyle 320 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.
