After upgrading 24/7 from a prior version, my alarm settings seem strange. How can I ensure my alarm will go off at the correct time?

If you see issues with your alarms, the best method is to delete all existing alarms and create new ones.

To do this, from the Record Sleep page, select the Alarm Setup button to see a list of your current alarms. Delete any existing alarms by pressing the Edit button, then touch the "Minus" icon followed by the Delete button. Now add a new alarm using the "Plus" button in the upper right.
