As soon as the weather station has established a connection with the outdoor sensor
it automatically begins to receive the DCF radio signal. This process takes several
minutes and is indicated in the LC display by a flashing radio tower symbol .

When the DCF radio signal is being successfully received, the radio tower symbol
is shown permanently in the display. If at the time of putting the device into opera-
tion it is not possible to synchronise with the atomic clock, you can also carry out
the clock adjustments manually ("Setting the 12 / 24 hour mode / °C / °F / hPa /
inHg / time zone / time / date / language manually").
Radio signal (DCF):
The DCF signal (time signal transmitter) consists of time pulses emitted by one of
the most accurate clocks in the world close to Frankfurt / Main, Germany.
In ideal conditions, your weather station can pick up this signal over a distance of
up to approx. 2000 km around Frankfurt / Main. Reception of the radio signal
generally takes approx. 3–10 minutes.
Reception can be considerably impaired by obstacles (e.g. concrete walls) or sources
of interference (e.g. other electrical devices). In the event of reception problems,
change the position of the weather station (e.g. to somewhere near a window).
