It runs with normal AAA batteries (2). These do not fit very well into the battery compartment, but to get them clean. The DCF reception works well with me. After about 3-5 minutes, the time has arrived. This is normal for DCF.
The display is clearly visible under normal lighting conditions.
Above the time and DCF signal can be seen.
In the second line, the date (without year), the day and - very nice - the moon phase (albeit somewhat roughly in 4 stages of new to full moon).
The third line contains the humidity and weather forecast. This is inherently uncertain, especially as the data comes from an interior sensor.
The bottom line contains the Tempeatur and (optional up to 3) outdoor sensors, which must be purchased separately but.
The accuracy of the temperature by 1-2 degrees to other sensors within the normal range. The 1/10 Gadzahlen can be ignored anyway weather stations in Consumer.
The humidity indicator is compared to other sensors such as 4-5% the same, so for humidity registration not uncommon bad, but not particularly accurate.
One can also let Max / Min Values.
A setting of alarm values the outdoor sensor is also possible led me but eventually lead to a disabling of the station so that no key worked. Therefore, I did not try this again.
The no. Of the outdoor sensor on the display is too small. Because you always have to approach very closely in order to recognize this.
Very annoying is that the buttons are all behind. To select the channel I would have liked a button on the front panel. Therefore 1 point deduction.
Otherwise, you can not complain for the price, especially the batteries for 1 year kept loose with me.
