By tapping the speaker icon at the top-left corner, you can toggle the event
mode of mobileCLOCK. If you tap and hold the icon then the 'Alert settings'
screen will be displayed.

This is the normal mode in mobileCLOCK, and all events will be active
and alarm and confirmation sounds are enabled.

This is the silent mode in mobileCLOCK, and all events will be active
but the alarm and confirmation sounds are muted.

All events are disabled, so no mobileCLOCK events will wake the device
and, consequently, no sounds will happen. This mode is useful if you
must prevent any sounds or vibration during a meeting, for example.
Note that the icon may appear slightly different on devices with older
OS versions, or on B/W screens.
