Options while on calls
Mute
Press MUTE/DELETE to silence the microphone. When mute is on, 
will show on the handset screen. You will be able to hear the caller, but your caller will not be able to hear you until you press MUTE/DELETE again and resume speaking. When mute is turned off, MICROPHONE ON will show temporarily on the handset screen. Mute is automatically cancelled when you end a call.
Temporary tone dialing
If you have only dial pulse (rotary) service, you can temporarily switch to touch tone dialing during a call by pressing TONE/*. This can be useful when send- ing tone signals for access to answering systems or long distance services.
After you hang up or press 
PHONE/FLASH (to receive a call waiting call), the telephone auto- matically returns to dial pulse (rotary) service.
