Getting started

Insert the batteries in the transmitter

• Place the base station and the transmitter on a table at a distance of about 1.5 meters from each other. Avoid being close to possible sources of interference such as electronic devices and radio equipment. Open the battery compartment of the transmitter and insert two new AA 1.5 V batteries, polarity as illustrated. All LCD segments will be dis-played for a short moment.
• The transmitter’s display shows the current temperature and humidity. The switch is set to channel 1.
• Close the battery compartment.

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 LCD segments will be displayed 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.

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 recep-tion symbol appear steadily on the base station display.
• If the reception of the outdoor values fails, “- -,-” 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
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 –/MIN button again for 3 seconds to stop 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 DCF reception

• If the clock cannot detect the DCF-signal (e.g. due to interference, transmitting distance, etc.), the time can be set manually.

• The clock will then work as a normal quartz clock (see: “Manual settings”).

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.

Operation

• The device will automatically quit the setting mode if no button is pressed for 20 seconds.
• Press and hold the MAX/+ or –/MIN button in setting mode for fast mode.

Manual settings

• Press and hold the SET button for three seconds to enter the setting mode.
  DEUTSCH (default) flashes on the display.

• Press the MAX/+ or –/MIN button to set the day-of-the week language: DEUTSCH, FRANCAIS, ITALIANO, ESPANOL, DUTCH, ENGLISH.

• If you select English, the display will now appear in English.

• Confirm with the SET button and go to the next setting.

• The sequence is shown as follows:

  • Language (default: DEUTSCH)
  • Button tone ON/OFF (default: BEEP OFF)
  • DCF reception ON/OFF (default: DCF ON)
  • Time zone -12/+12 (default: TIME ZONE 00)
  • Relative atmospheric pressure (default: PRESSURE: 1013 hPa)
  • Hour, minutes
  • Year, month, day

Wireless weather station
DCF reception

• By default, the DCF reception is activated (DCF ON) and after successful reception of the DCF signal no manual time setting is necessary.
• In the setting mode, you can deactivate (DCF OFF) or activate again the DCF reception using the MAX/+ or –/MIN button.
• Once the DCF time reception is deactivated the clock must be manually set. No time zone will appear.
• If the DCF reception is activated, the manually set time will be overwritten by the DCF time when the signal is received successfully.

Time zone setting

• In the setting mode you can make the time zone correction +12/-12). The time zone correction is needed for countries where the DCF signal can be received but the time zone is different from the DCF time (e.g. +1=one hour plus).

Atmospheric pressure setting

• In the setting mode, the relative atmospheric pressure at the installation site must be entered. Ask for the current atmospheric pressure of your home area (Local weather service, Internet, optician, calibrated 9. Comfort level instruments in public buildings and airport).

7. Maximum and minimum values

• Press the –/MIN button in normal mode. MIN flashes on the display.
• You can now see the lowest measuring value since the last reset with time and date of recording.
• The sequence is shown as follows: Outdoor temperature, outdoor humidity, indoor temperature, indoor humidity, atmospheric pressure.
• Press the –/MIN button once more to go back to the current values display.
• Repeat the process by pressing the MAX/+ button to see the maximum values. MAX flashes on the display.
• Press and hold the SET button for 3 seconds while the highest or lowest values are displayed. All values will be deleted and reset to the current state.

Trend arrows

• The trend arrows indicate whether the values for temperature and humidity of the last 15 minutes are increasing or decreasing. If the val-ues remain the same, there is no display.

Comfort level

• On the display appears a smiley to indicate the comfort level of the room climate (see Fig. 5).

Forecast
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”).

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 change (±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.

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. It 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.
• The landscape image changes with the seasons.
