Notes on the Telephone Line
❑
The internal fax modem can be connected to the subscriber telephone line.
Do not connect it to the PBX (Private Branch Exchange). Connecting to the
PBX may cause a failure or fire.
❑
Some PBXs may use the same electric requirements as the subscriber
telephone line of the local telephone company. Ask the manufacturer of your
PBX or your PBX maintenance agent for compatibility.
