12. DCF reception
The DCF signal is a signal broadcast from a
transmitter in Mainflingen (near Frankfurt am Main).
It has a range of up to 1500 km, increasing to 2000
km in ideal reception conditions.
Among other things, the DCF signal includes the
precise time (theoretical deviation of 1 second in a
million years!) and the date.
Of course, this eliminates the tedious manual
setting of summer and winter time on the weather
station, since the time change occurs automatically.
The first DCF reception test is performed once the
weather station has completed the search for the
outdoor sensor. Searching for the DCF signal and its evaluation will take a few minutes. Do not
move the weather station during this time and do not push any buttons.
A single successful reception per day will keep the deviation of the quartz clock in the weather
station below a second.
13. Troubleshooting
With this weather station, you have acquired a product that is built according to state-of-the-art
technology and is safe to operate. Even then, problems and malfunctions can occur. For this
reason, the following section provides an explanation on how to rectify possible malfunctions.
No reception of the outdoor sensor signal
If the weather station does not receive any measured data from the outdoor sensor, only dashes
are displayed in place of the outdoor temperature on the weather station display.
In this case, observe the following notes:
• The batteries in the outdoor sensor are weak or empty. Insert new batteries into the outdoor
sensor on a trial basis.
• The distance between the weather station and the outdoor sensor is too large. Change the
location of the weather station or outdoor sensor.
