Mute

Using Mute, you can silence any sound from the phone. This does not prevent incoming sound from being heard. Press during a call to activate Mute. The LED on the key indicates when Mute is active.

Since the 5304 phone does not have a handsfree microphone, the phone is effectively muted (no sound is transmitted to the other party) whenever the handset is on-hook. This does not prevent incoming sound from being heard.
