automatic on/off
This feature automatically disconnects the speakerphone
and turns it off when your phone is more than 20 feet away
for more than 20 seconds (actual distance is network/
phone dependent). When you return and open the car
door, the speakerphone turns on and tries to reconnect.
Note: Moving the speakerphone also turns it on.
To enable automatic on/off, just turn your
speakerphone on and leave the Power switch in the
center position.
When your speakerphone turns on or off, you hear an
audio tone.
