SUGGESTIONS
If your machine is set to Fax Detect ON, it is more sensitive to sounds.
Your machine may mistakenly interpret certain voices or music on the
line as a calling fax machine and respond with fax receiving tones.
Deactivate the fax by pressing Stop/Exit. Try avoiding this problem by
turning Fax Detect to Off. (See Fax Detect on page 4-4.)
If you answered at the machine, press Mono Start and hang up
immediately. If you answered on an extension phone, press your Fax
Receive Code (default setting is
your machine answers, hang up.
If you have Call Waiting, Call Waiting/Caller ID, Ring Master, an alarm
system or any other custom feature on a single phone line with your
machine, it may create a problem sending or receiving faxes.
For example: If you are sending or receiving a fax message while a
custom feature signal comes through on the line, the signal can
temporarily interrupt or disrupt the faxes. Brother's ECM feature should
help overcome this problem. This condition is related to the telephone
system industry and is common to all devices that send and receive data
on a single, shared line with custom features. If avoiding a slight
interruption is crucial to your business, we recommend a separate
phone line with no custom features.
