Ringer Vo l u m e
The Ringer Volume switch allows you to turn the
telephone ringer OFF, or set it to ring at LO or HI
volume. You can dial or answer calls normally when
the ringer is off. Other telephones in your home will
still ring; they are not affected by the switch.
Receiver (Handset) Vo l u m e
The Receiver Volume switch on the side of the hand-
set can be adjusted for a comfortable listening level.
The switch has three volume positions.
Te m p o r a ry Tone Dialing
Temporary tone dialing
is used only when you
have rotary service. It
allows you access to
services that require
tone signaling, includ-
ing some tone-activated
computer systems (e.g.,
telephone banking).
To change from pulse
( r o t a r y ) to tone dialing
during a call:
1 . Dial a telephone
number with the DIAL Mode switch set to
P U L S E .
2 . Press ; all buttons pressed after this will
send tone signals.
3 . After you hang up, the phone automatically
returns to rotary service.
