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).

falls sharply over a short period of time. This points to a potential gale or a storm brewing,

for example.

Frost warning

- A snowake symbol appears in the weather forecast display eld if the temperature measu-

red at the combination sensor falls below 4˚C.
