You can keep two-line telephones on other 
wall outlets as always. There are two ways to 
add a two-line telephone to the machine’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.

We suggest you ask the company who 
installed your PBX to connect your machine. 
If you have a multi line system we suggest 
you ask the installer to connect the unit to the 
last line on the system. This prevents the 
machine being activated each time the 
system receives telephone calls. If all 
incoming calls will be answered by a 
switchboard operator we recommend that 
you set the Receive Mode to Manual.
We cannot guarantee that your machine will 
operate properly under all circumstances 
when connected to a PBX. Any difficulties 
with sending or receiving faxes should be 
reported first to the company who handles 
your PBX.
