	and respond with fax receiving tones. Deactivate the machine by pressing
	Stop/Exit. Try avoiding this problem by turning Fax Detect to off. (See Fax Detect

	Activation Code (the factory setting is l 5 1 (l 9 1 for New Zealand)). When your

Custom features on a single line.	If you have Call Waiting, Call Waiting/Caller ID, an alarm system or other custom
	feature on a single telephone line with your machine, it may create a problem
	sending or receiving faxes.
	For example: If you subscribe to Call Waiting or some other custom service and
	its signal comes through the line while your machine is sending or receiving a fax,
	the signal can temporarily interrupt or disrupt the faxes. Brother's ECM (Error
	Correction Mode) 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 information on a single, shared line with custom features. If avoiding
	a slight interruption is crucial to your business, a separate telephone line with no
	custom features is recommended.
