The duration option sets the amount of time that the alarm sounds. The options
are 1 minute, 2 minutes, or 3 minutes. If you set the ringing duration to "1
minute", the alarm sounds for one minute, and then is silent. To stop the alarm
before a minute has passed, press "Backspace-enter".
The repeat interval defines the amount of time that is between the times that the
alarm sounds. For example, if you set the repeat interval to three minutes, after
the alarm has stopped sounding, it rings again in 3 minutes. The available
settings are 1, 3, 5, 10, 15, or 20 minutes.
If the alarm is not turned off by pressing "Backspace-enter", it repeats according
to the number of times you set the Wake Up Call Time option. The available
settings are 1 to 10.
Press "Enter" to save your setting, or "Space-Z" to cancel setting the alarm.
