Options while on calls

To adjust volume or sound quality

Press VOLUME buttons on the handset or the base to adjust listening volume. Each button press raises or lowers volume by one level.

During a handset call you can press SOUND SELECT to change sound quality. You can choose Natural Audio, Bass Boost, Mid Boost or Treble Boost. Each button press changes to the next tone type.

Call waiting

If you have Call Waiting service, you will hear a beep if someone calls while you are already on a call. Press FLASH to put your current call on hold and take the new call. You can press FLASH at any time to switch back and forth between calls.

Ring silencing

Press OFF while the handset is ringing (or MUTE while the base is ringing) to silence the ringer. You can still answer, or let the caller leave a message.

3-way conference calls

During an outside call, you can use both the handset and base (or two local handsets) to allow a 3-way conversation.

While a call is in progress, others can press PHONE (or SPEAKERPHONE at the base) to join the conference call. Others can press OFF (or SPEAKERPHONE at the base) to drop out of the conference call, but the call will not be terminated until all sets hang up.

Temporary tone dialing

If you have dial pulse (rotary) service, you can switch to touch tone dialing during a call by pressing *. This can be useful if you need to send tone signals for access to answering systems or long-distance services.
