Radio controlled clock reception
- Immediately after switch-on, the weather station attempts to receive the DCF-77 time signal
in order to set the clock automatically.
- If the weather station receives the time signal, the time and date are updated automatically
and a small reception indicator appears between the two items of data.
- The weather station attempts to synchronise with the DCF-77 transmitter every day at 04:00.
- If DCF-77-reception is not possible, the internal clock operates as a quartz clock.
- DCF-77-reception can be deactivated if necessary (refer to the “SYSTEM/DCF” menu).
Warning of extreme weather
- A warning symbol appears in the weather forecast display eld if the barometric pressure
falls sharply over a short period of time. This points to a potential gale or a storm brewing,
for example.
Frost warning
- A snowake symbol appears in the weather forecast display eld if the temperature measu-
red at the combination sensor falls below 4˚C.
