Actually, exactly what I was looking for, but ...

for the first time the alarm was not the time signal. Several manual reps managed no remedy. Actually I wanted to return the part already have it yet again placed in the bedroom. Contrary to expectations the unit functioned properly and there is every night since the signal easily.
The initial start-up took place in the living room, where naturally many sources of interference (TV, satellite receiver, AV receiver, mobile, wireless, ...). However, there are other 3 radio controlled watches that do not have this problem. One must conclude probably that this device is respect. Disorders sensitive than other radio controlled watches.
Otherwise, there's nothing but good TU report:
-Good operability (important functions via hardware switch)
-very bright lights with fade-out effect
-brightness Nightlight perfectly adequate (the large numbers of primitive times are not easy to read, anything but not necessarily)
-very easy to read display, even at an angle (side above / below)
-despite plastic solid appearance / pleasant feel.

Due to the limitation with respect. Radio reception only 4stars, otherwise almost perfect. Good price / performance ratio

Short supplement:
In fairness it should be mentioned that I now had the alarm 2 times with traveling and also because he has the time signal always found. What was going on there during the initial startup I do not know, but the clock appears usually no problems with the radio receiver to have.
