You can only mute the handset ringer if the handset is off the cradle when the phone starts ringing.
Traveling Out of Range
During a call, as you begin to move your handset too far from your base unit, noise
may increase. If you pass the range limits of the base unit, you will hear a beep and see Out of Range on the display, and then the handset returns to standby mode. You may return to the call if you move your handset within the range limits of the base and press talk/flash or speaker within 30 seconds
