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).
From 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).
