Turn Do Not Disturb on or off
When Do Not Disturb is on, a crescent moon icon 
will be displayed in the status bar. There are two ways to turn Do Not Disturb on or off:
Open Control Centre on your iPhone or iPod touch, or on your iPad. Then touch and hold the crescent moon icon to adjust your Do Not Disturb settings quickly or tap the crescent moon icon to turn it on or off.
If you've set an alarm in the Clock app, the alarm will go off even when Do Not Disturb is on. Find out how to set and manage your alarms.
Change your settings
If you don't want to be disturbed at a certain time, you can set a schedule. Tap Settings > Do Not Disturb, then turn on Scheduled and set a schedule. You can also choose when you want to receive alerts, calls and notifications:
- Silence: choose to silence calls and notifications at all times or only when the device is locked.
- Allow Calls From: allow calls from everyone, no one, your favourites or specific contact groups stored on your device or iCloud.
- Repeated Calls: if someone calls you twice within three minutes, the second call will not be silenced.
