In principle, the operation of the alarm is silent, however, make the keys a clear sound like closing a push button. The alarm can be adjusted reasonably comfortable about the SET button and the +/- keys. A bit annoying is that you will be asked each time to ask the seconds of the alarm - awakened is then but only to the minute. During the adjustment every four seconds the backlight goes out, so that you constantly have to switch it on again in the meantime. The alarm can be switched off by pressing the appropriate alarm button pretty easy prematurely. The snooze function can not be deactivated in advance. One can the snooze mode after waking but leave the SET 1 or SET 2 button. When alarm is a medium-loud, pushy tone with an average excited rhythm, without crescendo. The time is easy to read during the day. At night, the display is illuminated only relatively weak and not quite evenly. Nevertheless, the time can also be read at night properly, but only if the alarm is set slightly lower than eye level. As for the value, the alarm leaves a mediocre impression.
