4b) MANUAL SETTINGS

The appliance offers various options for changing the 

default settings. To do so, press the key 

[MODE]

 for 

three seconds to enter the setting mode. Every time the 

[MODE]

 key is pressed again, a flashing function which 

can be set appears on the display. 

Press one of the keys [      ] or [      ] respectively there. 

You can change the following functions (in this sequence; 

in between, simply press the 

[MODE]

 key each time):

-  Year

-  Calendar (Month – Day – Display Format 

  (Day/Month or Month/Day)

-  Time format 24h or 12h

-  Time (hours – minutes)

4c) Switching the radio reception off permanently

You have the option of switching the radio reception on or 

off and using the appliance as a normal quartz clock. 

Press the [      ] button for 3 seconds to switch the radio 

reception on or off. When the radio reception is switched

3. WEATHER FORECAST

3a) WEATHER FORECAST

Based on the change in barometric pressure, the receiver 

unit calculates the weather development for the next 12-24 

hours and indicates this with the following symbols:

Symbols on 

the display

Forecast
Symbols on 

the display

Forecast

3b) PLEASE NOTE THE FOLLOWING:

1. When the weather station has been put into operation, it 

is not necessary to set the current barometric pressure. 

The appliance will calculate over the next few hours a 

weather forecast from the changes in barometric 

pressure.

2. Lengthy, stable weather conditions make a weather 

forecast more difficult. A change in the weather symbol 

on the display may at times take longer than desired.

3. The weather forecast is calculated solely by means of 

changes in the barometric pressure.

4. The probability of the weather forecast is around 70% 

and applies for a radius of 20 – 30 kilometres.

5. If the symbol ‘sunny’ appears at night, this means 

cloudless weather. Fog is not displayed by the weather 

station as this can occur with different weather 

conditions.

6. If you take the weather station with you on your travels, 

the weather forecast will alter due to the differences in 

height above sea level and the resulting changes in 

barometric pressure. Please wait up to 24 hours until the 

weather station has calculated the weather forecast 

based on the barometric pressure conditions at your new 

location. 

3c) BAROMETRIC PRESSURE – TENDENCY 

DISPLAY

The indicator for the barometric pressure tendency in the 

weather forecast window indicates the trend in 

barometric pressure change in the previous hour. Three 

different indicators are displayed:

Note: By default, the barometric pressure measured is 

displayed in 'mbar/hPa'. The pressure is the pressure 

measured locally; it cannot be set to the sea level. 

Frost alarm

The frost alarm symbol appears on the display when the 

outdoor temperature falls below 3°C (This is transmitted 

by the external sensor on channel 1). When the 

temperature rises above +6°C, the symbol disappears 

again.

4. RADIO CLOCK

4a) NOTES ABOUT THE RECEPTION OF THE 

TIME SIGNAL

The appliance is designed in such a way that the calendar 

clock is automatically synchronised as soon as it is within 

the range of the DCF77 signal. 

To ensure a good reception of the time signal and 

minimise interference, you should not set up the appliance 

in the vicinity of metallic objects or electrical appliances.
It normally takes around 3 to 5 minutes until the signal is 

fully received for the first time (depending on the strength 

of the time signal received). The subsequent hourly 

synchronisation of the time then only takes a few seconds.
If the reception problems persist, please set the clock 

manually and wait until the next morning. The chances of 

successful reception are greater in the night (from 

midnight to around 4 am). One successful reception per 

week is perfectly sufficient to ensure that the clock runs 

precisely.
