Getting started

Insert the batteries

• 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 displayed for a short moment.
• The display shows the temperature. The switch is set to channel 1.
• Close the battery compartment.
• Open the battery compartment of the base station.
• Insert two new AA 1.5 V batteries, polarity as illustrated. All LCD segments will be displayed for a short moment. The indoor temperature appears on the display.
• Close the battery compartment.

Reception of outdoor transmitter

• The base station will scan the outdoor temperature and the reception symbol flashes

• If the reception is successful, the outdoor temperature and the reception symbol appear steadily on the base station display.

• If the reception of the outdoor temperature fails, “- -,-” remains on the 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 outdoor data takes place immediately and if the reception is successful, the outdoor temperature appears on the base station display.

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 3-10 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 the
  –/MIN button 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.
• The first adjustable value flashes on the display.
• Use the MAX/+ or –/MIN button to make the desired setting, while the value flashes.
• Confirm with the SET button and go to the next setting.
• The sequence is shown as follows:
  • DCF reception ON/OFF (default: DCF ON)
  • Time zone -12/+12 (default: DCF 00H)
  • Hours, minutes
  • Year, month, day
  • Automatic reset of the maximum and minimum values ON/OFF (default: AUTO OFF MAX MIN)

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, use the MAX/+ or –/MIN button to 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)

Automatic reset of the maximum and minimum values

• In the setting mode, you can activate (AUTO MIN MAX ON) or deactivate again the automatic reset of the maximum and minimum values using the MAX/+ or –/MIN button.
• If the automatic reset is activated, AUTO appears on the display.
• The maximum and minimum values will be reset automatically every midnight at 0:00 (see “Reset of maximum and minimum values”).

Temperature

Indication of maximum and minimum values

• Press the –/MIN button in normal mode. MIN flashes on the display.
• You can now see the lowest indoor temperature measuring value since the last reset with time and date of recording.
• Press the –/MIN button and go to the outdoor temperature.
• If you have installed more than one transmitter, press the CHANNEL button to change between the outdoor transmitters.
• 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.

Reset of maximum and minimum values
a) Manual reset

• Press and hold the SET button for 3 seconds while the highest
  or lowest values are displayed. The values will be deleted and reset to the current state.

b) Automatic reset

• Provided that in the setting mode the automatic reset is activated (AUTO MIN MAX ON). AUTO appears permanently on the display.
• All maximum and minimum values will be reset automatically every midnight at 0:00.
• An interim manual reset is still possible.

Forecast

Weather forecast symbols (Fig. 4)

• The weather station has 6 different weather symbols: sunny, slightly cloudy, cloudy, rain, storm, snow.
• Snow is shown if rain is forecasted and the outdoor temperature on channel 1 is under 0 °C.
• The weather forecast covers a range of 12 – 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 atmospheric pressure has dropped and the weather is expected to get worse but not necessarily rain. The accuracy is about 70-75 %.

Weather Jack (Fig.4)

• Weather forecast by ”Weather Jack”: Shorts, scarf, gloves or umbrella? ”Weather Jack” shows in 28 variations always the correct clothing for the current weather and the outdoor temperature.
• Please keep in mind that the clothing state is based on the information of the transmitter received on channel 1. If this transmitter is not situated outside or if there is no transmitter connected to channel 1, a wrong or no display will be the result.

Trend arrows

• The trend arrows on the display will show whether the atmospheric pressure of the last 3 hours is increasing, steady or decreasing.

| Increase (+1-2 hPa)| Weather improvement
---|---|---
| Fast increase (>+2hPa)| Significant weather improvement
| Steady (±1hPa)| Stable weather conditions
| Decrease (-1-2 hPa)| Weather deterioration
| Fast decrease (>-2hPa)| Significant weather deterioration

Location and mounting

• When placed outdoors, choose a shady and dry place for the transmitter. Direct sunlight may trigger incorrect measurement and continuous humidity damages the electronic components needlessly.
• Place the base station in any room of the house.
• Avoid being close to possible sources of interference that may affect radio reception. It is recommended to keep a distance of at least 2 metres to possibly interfering sources (TV, computer, microwave, wireless phones, baby monitors) and large metal objects (e.g. refrigerator). Within solid walls, especially ones with metal parts, the transmission range can be reduced considerably. In extreme cases, please place the unit close to a window to improve reception.
• Check whether the transmission from the transmitter to the base station is possible and whether the DCF radio clock signal can be received.
• If necessary, choose another position for the outdoor transmitter and/or receiver.
• If the transmission is successful, you can place or wall mount the base station and the outdoor transmitter with the suspension device.
• To wall-mount the transmitter, screw the holder to the wall and click the outdoor transmitter into the holder.
• Do not use the base station in the vicinity of radiators, other sources of heat or in direct sunlight.

Battery replacement

• As soon as the battery symbol will appear on the outdoor values display of the base station or on the display of the outdoor transmitter, change the batteries of the outdoor transmitter.
• Change the batteries of the base station, when the battery symbol appears on the indoor values display.
• Please note: When the batteries are changed, the contact between the transmitter and the receiver must be restored – so always insert new batteries into both devices or start the manual search for the transmitter.

Additional outdoor transmitters (optional)

• When having more than one external transmitter, select a different channel for each one with the 1 2 3 switch inside the transmitter’s battery compartment. Insert two new AA 1.5 V batteries, polarity as illustrated. Start the base station operation or the manual search for the outdoor transmitter:
  • Choose the respective channel by pressing the CHANNEL button.
  • Press and hold the CHANNEL button for three seconds. The last registered transmitter (channel) will be cancelled and the transmitter search begins.
  • Press the TX button in the corresponding transmitter’s battery compartment. The transmission of the outdoor data will take place immediately.
• The outdoor values and the channel number will be shown on the base station display. If you have installed more than one outdoor transmitter, press the CHANNEL button on the base station to change between the channels 1 to 3.
• You can also choose an alternating channel display. Press the CHANNEL button. After the last registered channel (1 to 3) a  circle symbol will appear. To deactivate the function press the CHANNEL button again.
• After a successful installation close the outdoor transmitter’s battery compartment carefully.
