1 The Multimessage Systems MULTI 4 Telephone System is suitable for

connection to Exchange lines which provide Multi-Frequency (MF)
signalling. Multimessage Systems MULTI 4 can be used with Timed
Break Recall (TBR).

2 Only connect apparatus which has been approved for connection to

your analogue Public Switched Telephone Network. This will usually
have a lable with “APPROVED for connection to telecommunication
systems specified in the instructions for use subject to the conditions
set out in them”. Any other connection may cause damage or become
hazardous and will invalidate the approval of the apparatus if as a
result it then ceases to comply with the standards against which
approval was granted.

3 The Multimessage Systems MULTI 4 system is designed to operate

with a mains supply of 220-240Vac 47-63Hz with a maximum power
consumption of 16W.

4 The system is not suitable for use as an extension to a payphone.

5 Wiring from the Multimessage Systems MULTI 4 Box to the extensions

must be confined to the same premises and must not exceed a length
of 200 metres.

6 It is permitted to connect Multimessage Systems MULTI 4 as a

satellite to a PBX (Private Branch Exchange). However, satisfactory
performance cannot be guaranteed with every allowable combination
of host and subsidiary system.

7 Refer all servicing to qualified personnel or to the Multimessage

Systems Customer Servicing Department at the address given on the
back page of this handbook.

8 The line cord and mains cable must be disconnected before

removing the cover of the Multimessage Systems MULTI 4 Box.

TECHNICAL NOTES - cont’d

How many telephones can you connect?

This is important if you want to connect more than one piece of apparatus to
each extension. Each instrument (telephone, fax machine etc.) has a REN
(ringer equivalence number) value, which is usually written on it somewhere.
The total REN value of all instruments connected to an extension must not
be more than 4. If you have a BT telephone, you can assume that its REN
is 1 unless it is marked otherwise. If you connect telephones such that the
total REN value is more than 4 to one extension line, one or more of the
instruments will not ring and/or answer calls correctly.

Multi 4 is a small telephone system intended for use in the home, office or
small business. It serves up to four internal telephone extensions from one
Exchange Line. It provides both a high quality intercom between extensions,
and access to the outside line from each extension, with total privacy on all
calls.
It consists of a compact unit which can be wall-mounted in any convenient
position, its small size and smart appearance helping to blend into its
surroundings. It is mains powered, and is fitted with a three-metre cable,
terminating in a standard telephone plug, for connection to a BT socket.

It is simple to operate and easy to install using ordinary 2-wire telephone
cable and master BT-type sockets. Extensions may be situated up to 200
metres from the central control unit.

Advanced microprocessor technology has enabled a number of special
features, normally available in larger, expensive systems to be provided.
