Multi-line connections (PBX)

7

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.

Receive Code. When you press the Fax
