To define the alarm time, simply click on the currently defined time and select the time you wish for the alarm. You must also activate this alarm via the option “activate”.
The item “repeat” lets you select which on weekdays should the alarm be repeated. If you only want the alarm to go off once, select the option “just once”.
The length of time the alarm is active can be set under “extended” by activating the option “activate extended settings”. You will need the active alarm time if you want the alarm to last for a specific time. For example, if you have activated the alarm for 8pm with an active time of 10 minutes, then the alarm is active from 8 pm till 8:10 pm and then switches itself off. If you haven’t activated this option then the alarm stops directly after the trigger.
