1

Place the two-line TAD and the two-line 
telephone next to your MFC.

2

Plug one end of the telephone line cord 
for your MFC into the L2 jack of the 
triplex adapter. Plug the other end into 
the LINE jack on the back of the MFC.

3

Plug one end of the first telephone line 
cord for your TAD into the L1 jack of the 
triplex adapter. Plug the other end into 
the L1 or L1/L2 jack of the two-line TAD. 

4

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.

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 MFC 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. 

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.

If you are installing the MFC to work 
with a PBX

1

It is not guaranteed that the unit will 
operate properly 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.

Custom features on your 
phone line

If you have Voice Mail, Call Waiting, Call 
Waiting/Caller ID, RingMaster, an answering 
service, an alarm system or other custom 
feature on one phone line it may create a 
problem with the operation of your MFC.
