6. Getting started
• 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.
• Remove the protective film from the base station display.
• Open the battery compartment at the back of the base station.
• Insert three new AAA 1,5 V batteries into the battery compartment. Make sure the polarity is correct.
• Close the battery compartment again.
• The device will alert you with a beep and all segments will be displayed for a short moment.
• Optional: For a permanent backlight and to conserve battery power, you can operate the base station with a suitable power
supply.
6.1 Inserting the batteries in the outdoor transmitter/Reception of outdoor values
• Slide down the battery compartment lid of the transmitter.
• Insert two new batteries 1,5 V AAA into the outdoor transmitter's battery compartment. Make sure the polarity is correct.
The LED signal lamp flashes.
• The base station automatically starts scanning the signals to register the outdoor transmitter at channel 1 after batteries
are inserted. The reception symbol for the transmitter flashes.
• As soon as the base station receives the outdoor values, the values are permanently shown.
• If the reception of the outdoor values fails within three minutes, "- -" appears on the display. Check the batteries and try it
again. Check if there is any source of interference.
• You can also start the outdoor transmitter search manually later on (for example when the outdoor transmitter is lost or the
batteries are changed).
• Press and hold the CHANNEL button on the base station for three seconds.

• "- -" appears on the outdoor values display and the reception symbol flashes.
• After a successful installation close the battery compartment of the outdoor transmitter carefully.
6.2 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 3-8 minutes, the radio-controlled time, the date, the day of the week 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 reception is not successfully
received at 3:00 o'clock, further attempts will be taken until 5:00 o'clock.
• You can also activate the DCF reception manually.
• Press and hold the DOWN button for 3 seconds.
• The DCF reception symbol flashes.
• Press the DOWN button again to deactivate the DCF time reception. The DCF reception symbol disappears.
• Important: The device cannot be operated during the DCF time-signal reception.
• There are three different reception states:
flashing – reception is active
flashing – signal is found
solid – reception is very good
• 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).
6.3 Note on radio-controlled time
The time base for the radio-controlled time is a caesium atomic clock operated by the Physikalisch Technische Bundesanstalt
based in Braunschweig (Brunswick), Germany. It has a time deviation of less than one second in one million years. The time
is coded and transmitted from Mainflingen near Frankfurt via the frequency signal DCF-77 (77.5 kHz) and has a transmitting
range of approximately 1,500 km. Your radio clock receives the signal, converts it and always shows the exact time. The
adjustment to Daylight Saving Time (summer/winter time) is automatic. The reception quality depends mainly on geographic
location. Normally there should be no reception problems within a 1,500 km radius around Frankfurt.
