The Alarms tab allows you to set varying alarm clocks. You can set an alarm by modifying an existing alarm or by adding a new one. After you've created one or more alarms, you can easily activate or deactivate an alarm by tapping its Alarm icon to toggle it on (blue) or off (grey).
On the Home screen, tap the Apps Key > Alarm/Clock .
Tap the Alarms tab at the top of the screen, if necessary.
Tap the New alarm icon at the bottom of the screen to add a new alarm or tap a current alarm icon on the right side of the screen to activate an existing alarm (when the icon is blue, the alarm is set).
