Do Not Disturb mode
The Do Not Disturb mode is a setting that mutes all sounds and vibrations, making it a very useful option when wearing the watch in, for example, a theater or any environment where you want the watch to operate as usual, but silently.
The Do Not Disturb mode also prevents the watch from going into hibernation after a period of inactivity
To turn on the Do Not Disturb mode:
From the watch face, press the middle button to open the shortcuts menu. You will find the Do Not Disturb option on top of the list and pre-selected.
Tap the screen or press the middle button to confirm the selection.
While in this mode, press any button to activate the exit option. Then press the upper right button to turn off the Do Not Disturb mode.
If you have an alarm set, it sounds as normal and disables Do Not Disturb mode unless you snooze the alarm.
