When set to ring mode, iPhone plays all sounds. When set to silent mode, iPhone
doesn’t ring or sound any alerts or sound effects. Alarms set using Clock do sound,
however. By default, when you get a call, iPhone vibrates whether it’s set to ring or
silent mode. If iPhone is set to ring mode, you can silence a call by pressing the Sleep/
Wake button or one of the volume buttons once. Press a second time to send the call
to voicemail.
For information about changing sound and vibrate settings, see page 99.
Using the Stereo Headset
The headset included with iPhone features a microphone and an integrated button
that allows you to answer and end calls easily, and control audio and video playback.
