Technical information

All items of telephone equipment have a Ringer Equivalence Number (REN)
which is used to calculate the number of items that may be connected to
any one telephone line.

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 then the RENs add up to
no more than 4.

Your Duet 600 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.

If the REN of 4 is exceeded, the telephone may not ring. With different
telephone types there is no guarantee of ringing, even when the REN is
less than 4.

This equipment complies with the essential requirements of the Radio
Equipment and Telecommunications Terminal Equipment Directive,
1995/5/EC.

Switchboard compatibility

This product is intended for use within the UK for connection to the
public telephone network and compatible switchboards, which support
tone dialling and time break recall. If in doubt please consult your service
provider.

Wall mounting

Use the template in the left hand margin to drill holes in the wall.
Pull out the wall mounting catch on the base unit, reverse it and replace it.

The handset will now be able to rest on the hook when your Duet 600 is
wall mounted.
