TELEPHONE OPERATION

PROBLEM	SOLUTION
LINE Lights Remain	• Make sure the phone is programmed
On When No Line is	for that line to be absent. (See “Turn
Connected	Line Usage On or Off for Each Line”
	on page 37.)
	• Make sure that your Line Groups are
	programmed properly. (See “Assign the
	Line Group for this Phone” on page 50.)
	• Disconnect all other devices (fax, modem,
	credit card reader, etc.) from any lines
	connected to your 945 phone. These
	devices can interfere with the telephone’s
	data links.
	• Make sure the total length of telephone
	wiring used in your phone system is less
	than 600 feet. In some cases a Z800A
	filter can be used in a phone system with
	more than 600 feet of wire. AT&T highly
	recommends that a Z800A filter be installed
	by a professional. AT&T CANNOT
	guarantee that this telephone will work
	with such a filter, and IS NOT responsible
	for such installations. A Z800A filter can
	be obtained by calling 800 222-3111.
	(See “DSL Users” beginning on page 4 for
	details.)
