Fault/Remedy
Fault
Possible Cause
The DCF77 signal for the time cannot be
received.
Check the chosen location.
Start the signal reception manually,
if necessary.
Adjust the time manually.
Temperature indication appears too high.
Check whether the device is
exposed to direct sunlight.
Instead of showing the measured values for
temperature or humidity, the display shows
H.HH or LL.L.
The values lie above or below the
measurement range.
The indicator is illegible, the function is
unclear, or the values are obviously false.
Disconnect the radio alarm clock
for a few moments from the power
supply.
The time differs by exactly one, two, three,
etc. hours.
You have probably set an incorrect
time zone.
