Who thinks something out ?!

I thought: What can you do already wrong in a radio alarm clock? It works! So: If you set the alarm clock, each button is acknowledged by the already penetrating loud alarm. For each paying agency so a beep. In practice, this means: If you want to only set the alarm at night or morning hang another hour etc .: you will make in your roommates who sleep already or still, very popular. Why use an acoustic confirmation? (The course can not be canceled.)
(Want to be and all that's) Empfehlensswert for students living away, hard of hearing people, which alone do not want to rely on your eyes: Ergo.
