Silent Mode
Silent mode is convenient when you wish to stop the phone from making a sound, in
a theater, for example.
In Idle mode, press and hold until the phone vibrates, the “Silent profile on”
message appears on screen. The Silent mode icon is displayed on the screen.
For more information, refer to “Sound Profile” on page 54.
In Silent mode, your phone speakers are muted. An incoming call causes the phone
to vibrate and light up, depending on the settings of the Silent Phone Settings
feature.
To exit and reactivate the previous sound settings, press and hold again until
the previous Sound Profile is restored. The Silent mode icon is no longer displayed.
