If I had this clock, I would just set AL1 and leave it at that.
Just to let you know there is also a limit on how long the alarm will go off. I have had my alarm go off all day cause I forgot to turn it off but woke up before it goes off so this limit would be handy. You can change how long the clock will go off till it shuts off if you don't turn it off. The default setting is 30 minutes before it shuts off on its own.
I may buy this clock in near future just for that feature!
