TROUBLESHOOTING AND ROUTINE MAINTENANCE 12 - 12
Handling Incoming Calls
Machine ‘Hears’ Voice as
CNG Tone. 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.)
Transferring a Fax Call to the
machine. 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 ( 51). When your machine answers,
hang up.
Custom features on a single
line.
If you have Call Waiting, Call Waiting/Caller ID, Ring Master, BT’s Call
minder, 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 telepho ne
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.
