HTC One M8 for Windows - Manual (Page 62)

Setting quiet hours
Cortana can turn on quiet hours when you don't want to be disturbed by
phone calls, notifications, or messages. When quiet hours is enabled,
notifications will be silent, and phone calls will go voicemail, unless you told
Cortana to allow calls from people in your inner circle.
1. In Cortana, tap > quiet hours.
2. Tap the Automatic rules On/Off switch and then select Turn on
during these times or Turn on when I have a calendar event
marked Busy to set the times you want quiet hours to turn on.
To manually turn on quiet hours, tap the Right now On/Off switch.
3. Under Breakthrough rules, set whose calls or texts will be allowed
to bypass quiet hours time settings.
Adding people to your inner circle
When quiet hours is turned on, Cortana won't let calls or messages bother
you. However, you can add important people to your inner circle so they
can always get in touch with you.
1. In Cortana tap > inner circle.
2. Tap someone in the list or tap to search for the contact you
want to add.
