SETUP & PREPARATION BEFORE USE
FOR YOUR INFORMATION

Multi Line Connections (PABXs)

Most offices use a central telephone system. While it is often relatively simple to connect
the machine to a key system or a PABX (private automatic branch exchange), we suggest
that you contact the company which installed your telephone system and ask them to connect
the fax machine for you.
It is advisable to have a separate line for the fax machine. You can then leave the machine
in FAX mode to receive faxes at any time of the day or night.
If the fax machine is to be connected to a multi-line system, ask your installer to connect the
unit to the last line on the system. This will prevent the unit from being activated each time
a telephone call is received.

Connecting to a Private Automatic Branch Exchange

The following points should be kept in mind if you are installing the machine to work as an
extension to a private automatic branch exchange (PABX).
1) It is not guaranteed that the unit will operate correctly under all circumstances with
PABXs. Any cases of difficulty should be reported first to the company that handles
your PABX.
2) If all incoming calls will be answered by a switchboard operator, it is recommended that
the Answer Mode be set to be MANUAL; see chap. 7. All incoming calls should initially
be regarded as telephone calls.
3) The unit may be used with either pulse or tone dialling telephone lines.

Ringer Equivalence Number (REN) (For U.K. only)

This equipment has a REN value of 1. A BT line has a "bell ringing" capacity, or REN, of
4. This means that adding downstream-connected extension telephones and/or extension
bells to a total REN of greater than 4 may cause a reduction in the bell volume. In extreme
cases, it may cause the auto-answer facility of the machine to fail.
Therefore, up to three additional extension telephones (each assuming a REN of 1), may be
connected downstream of your machine. For an explanation of "downstream connection,
read "Using extension telephones" which follows.
Unless otherwise marked, a telephone provided by BT may be assumed to have a REN value
of 1.
