Plug one end of the second telephone line cord for your TAD into the L2 jack
of the two-line TAD. Plug the other end into the EXT. jack on the left side of
the MFC.
Triplex Adapter
You can keep two-line telephones on other wall outlets as always. There are two
ways to add a two-line telephone to the MFC's wall outlet. You can plug the
telephone line cord from the two-line telephone into the L1+L2 jack of the
triplex adapter. Or, you can plug the two-line telephone into the TEL jack of the
two-line TAD.

Multi-Line Connections (PBX)

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 MFC for you. It is advisable to have a separate line
for the MFC. You can then leave the MFC in FAX mode to receive faxes any
time of day or night.
If the MFC is to be connected to a multi-line system, ask your installer to
connect the unit to the last line on the system. This prevents 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 MFC cannot be
made.

If you are installing the MFC to work with a PBX:

1
It is not guaranteed that the unit will operate correctly under all circumstances
with a PBX. 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
recommended that the Receive Mode be set to MANUAL. All incoming calls
should initially be regarded as telephone calls.
3
The MFC may be used with either pulse or tone dialing telephone service (Only
For Canada only).
