Well, as said a buyer, it is difficult to configure, it is not +5 it takes is Bac + 20 !!! In truth, we must simply read the instructions in English (bad translation French who forgot words ....)! or have a brain of man (as the other two comments!) It took me three days to understand 5minutes ... in English! I'm like the guy very happy with this purchase, "this lamp has all the interesting options." Dear Madam, if you read this comment so that the lamp does not turn too quickly, adjust the intensity and lighting time: So you set your alarm clock at 7:30 to trigger sounds "waves, birds beep, then the ignition time = 30 minutes prior to me = it starts at 7:00 am and also the intensity, I'm still testing between 5/10/15/20. 9a lights softly. Then, and this is what I could not do ... everyone will laugh: it is necessary to "ON" instead of "Day" once one has chosen today (myself I have 3 different!) to turn it on! and ESPECIALLY "OFF" if you do not want it to fire. The first time the three alarms have Sonne- for help: 5:30 / 6:30 ET 9:00 a ... Sunday! What is cool is that I can put Mozart via USB key or other music! Those who read German, read the instructions directly in this language! Many greetings!
