GB
5.2 Getting the base station started
- The base station can be operated with a mains adapter and/or with 3 x 1.5 V AA batteries (not included). The batteries maintain the function in the event of a power failure, so that no readjustment has to be made and the memory values are retained. For a permanent backlight and to conserve battery power, use the supplied power adapter.
- Insert the power adapter pin into the device jack and connect the plug to a wall socket.
• The device will alert you with a beep and all LCO segments will be declared for a short moment.
• The device is ready for use
- Optional: Open the battery compartment and insert three new AA 1.5 V batteries, polarity as illustrated. Close the battery compartment.
5.3 Reception of outdoor transmitter
- The base station will scan the outdoor values and the reception symbol flashes.
- If the reception is successful, the temperature, humidity and the reception symbol appear steadily on the base station display.
- If the reception of the outdoor values falls, “--,” remains on the base station display. Check the batteries and try it again.
- You can also start the transmitter search manually later (e.g. if the transmitter signal is lost or if the batteries are changed): Press and hold the CHANNEL button on the base station for three seconds. The reception symbol for the outdoor transmitter will be flashing. Press the TX button in the transmitter's battery compartment. The transmission of the data takes place immediately and if the reception is successful, the outdoor values appear on the base station display.
- if the transmitter signal is lost, the device automatically starts a transmitter search for 60 seconds after 30 or 60 minutes.
Wireless weather station
5.4 Reception of the DCF frequency signal
- After the reception of the outdoor values, the clock will now scan the
DCF frequency signal and the DCF symbol flashes on the display.
- When the time code is successfully received after 3-15 minutes, the radio-controlled time and the DCF symbol will be shown steadily on the display.
- The DCF reception always takes place at 1:00, 2:00 and 3:00 o'clock in the morning. If the signal is not successfully received, further attempts will be taken at 4:00 and 5:00 o'clock.
- You can also activate the DCF reception manually. Press and hold the -MIN button in normal mode for 3 seconds. The DCF reception symbol will be flashing.
- Press and hold the -IMIN button again for 3 seconds to step the reception process. The DCF reception symbol disappears.
- There are 3 different reception symbols:
flashing symbol - reception is active
solid - reception is successful
no symbol - no DGF reception
- If the clock cannot detect the DGF-signal i.e. due to interference,
• The clock will then work as a normal quartz clock (see "Manual settings").
5.5 Note on radio-controlled time
- The time is transmitted from an atomic clock near Frankfurt am Main by a DCF-77 (77.5 kHz) frequency signal with a range of about 1,500 km. Your radio-controlled clock receives the signal, converts it and always shows the exact time. The adjustment of Daylight Saving Time and Standard Time is also automatic.

- Avoid being close to possible sources of interference that may affect radio reception (see "Location and mounting").
- During night-time, the atmospheric interference is usually less severe. A single daily reception is adequate to keep the accuracy deviation under 1 second.

Temperature/humidity are decreasing
9. Comfort level
- On the display appears a smiley to indicate the comfort level of the room climate (see Fig. 5).
10. Forecast
10.1 Atmospheric pressure
- The relative atmospheric pressure is referred to the sea level's pressure and has to be adjusted first to your local altitude (see: "Manual settings").
Wireless weather station
10.2 Developing of atmospheric pressure
- The bar graph indication of atmospheric pressure shows the last 24 hours.
- The '0' in the middle of this scale is equal to the current pressure and each charge (±2, ±4, ±6) represents how high or low in 'hPa' the past pressure was compared to the current pressure.
- If the bars go down, it means the atmospheric pressure has dropped and the weather is expected to get worse.
- If the bars are rising it means that the weather is getting better.
10.2 Weather forecast symbols
- The weather station has 6 different weather symbols: sunny, slightly cloudy, cloudy, rainy, thunderstorm, snowfall.
- A snow crystal is shown if rain is forecasted and the outdoor temperature on channel 1 is under 0°C.
- The weather forecast relates to a range of 12 to 24 hours and indicates only a general weather trend. For example, if the current weather is cloudy and the rain symbol is displayed, it does not mean the product is faulty because it is not raining. If simply means that the air pressure has dropped and the weather is expected to get worse but not necessarily rain. The accuracy is about 70 - 75% .
Note:
- Please note that the forecast symbol will become more defined in the course of operation. The forecast symbol is active right from the start, however, the reliability of the forecasts increases with the amount of data collected. To begin with, the sensor must adapt initially to the reference level at the site.
