Call waiting
Use this feature to control call-waiting calls. If you 
subscribe to a call waiting service with your local 
telephone company, there is a beep if there is an 
incoming call when you are already on a call on 
the same line.
1. Press 
[FLASH] to put your current call on hold 
and take the new call. 
2. Press 
[FLASH] anytime to switch back and forth 
between calls. For more information on caller ID 
with call waiting, see page 57.
MUTE
Use this feature during a telephone conversation 
to silence the microphone. Press [MUTE]. You hear 
the other party, but the other party does not hear 
you. Press [MUTE] again to cancel. Mute cancels 
automatically when you end a call.
When mute is active, the MUTE light is on.
 NOTE: Switching from handset to speakerphone    
or headset, or from speakerphone or headset to 
handset, changing lines, or putting a call on hold 
also cancels the mute function.
Temporary tone dialing
If you have dial pulse (rotary) service only, use this 
feature to temporarily switch dial pulse to touch-
tone dialing during a call by pressing [*TONE].
1. Dial the number.
2. Press and release 
[*TONE]. Buttons pressed after 
this send touch-tone signals.
3. After you hang up, the phone automatically 
returns to pulse dial mode.
