Unfortunately, the alarm will beep very loudly at every keystroke! The wake-up time can be adjusted with the button AL SET on the back and the arrow keys on the front. The illumination of the display remains switched on automatically as long as you enter the new alarm. But you have to be careful: If you press accidentally WAVE instead AL SET, the alarm clock for a few minutes can no longer make do. The alarm can be switched off prematurely via the slide AL ON / OFF on the back. The snooze function can not be deactivated in advance. One can the snooze mode after waking only to the slider AL ON / OFF to leave on the back. When alarm is a loud, short sound with an average excited rhythm, without crescendo. The time is easy to read during the day, at night also, but only if the alarm is set slightly lower than eye level. The display is illuminated perfectly. The alarm clock makes a high impression. In my search for a radio alarm clock I've tested 33 radio alarm clock. If you're interested, you can test all 33 Funkwecker under "Articles" read on stefanrohloff.de.
