Multi Line Connections (PBXs)
Most offices use a central telephone system. While it is often relatively simple to
connect the machine to a key system or a PBX (private branch exchange), we suggest
that you contact the company that 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 AUTO Answer 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.
• As with all fax units this machine must be connected to a two wire system. If your
line has more than two wires, proper connection of the fax machine can not be
made.
Connecting to a Private Branch Exchange
The following points should be kept in mind if you are installing the machine to work
with a private branch exchange (PBX).
1) It is not guaranteed that the unit will operate correctly under all circumstances
with PBXs. Any cases of difficulty should be reported first to the company that
handles your PBX.
2) If all incoming calls will be answered by a switchboard operator, it is recom­
mended that the Answer Mode be set to be MANUAL. (Seepage 7-2.) All incoming
calls should initially be regarded as telephone calls.
3) The unit may be used with either the pulse or tone dialing telephone types.
Custom Features on Your Phone Line
If you have Call Waiting, Ring Master, Voice Mail, an Answering Service, Alarm
System or any other custom feature on your telephone line it may create a problem
in the operation of your fax machine.
