Telephone System Guidelines
• Your telephone system may be programmed for one or two dial tones. Systems
with two dial tones have one for intercom calls and one for outside calls.
• Many features “time out” if you wait too long before performing the next step. If
this happens, you must hang up and start again.
• If you hear four fast tones or repeating fast tones, you have pressed an invalid
button combination, tried to select a restricted line, dialed a restricted or invalid
number, dialed too slowly between digits, or waited too long before performing
the next step. Hang up and try again.
• If your endpoint has been reprogrammed by the installer so that its feature but-
tons do not match the feature buttons described in this user guide, refer to the
Administrator’s Guide for procedures on using feature codes. Default feature
codes are listed on the back of this user guide.
• The Handsfree Mode feature code (319) must be turned off. Otherwise, when a
user receives an incoming call, the endpoint will ring only once and the display
will show the party’s extension number once and goes back to the idle mode. To
turn the feature off, press and dial .
