6. Getting started

• Open the battery compartment and insert three new batteries 1,5 V AA, polarity as
illustrated. Close the battery compartment again.
• The device is ready for use.
• The device will alert you with a beep.
• The alarm time (default 6:00) and the alarm time symbol appear in the display.
• The clock's hands move to 12.00 o'clock.
• The clock will now scan the DCF frequency signal. The DCF symbol is flashing on the
display.
• When the time code is received successfully after 3-12 minutes, the digital time
appears briefly on the display and the analogue clock updates to the radio-controlled
time. The DCF symbol appears steadily on the display.

6.1 DCF reception

• The DCF reception always takes place at 1:00, 3:00 and 5:00 o'clock in the morn-
ing. If the reception is not successfully received until 5:00 o'clock, the next receive

Radio-controlled alarm clock
• The DCF symbol will be flashing.
• To deactivate the DCF reception, press and hold again the + button for three
seconds.
• The DCF symbol disappears.
• There are three different reception symbols:
flashing - reception is active
stays - reception is very good
no symbol - reception is deactivated
• If the clock cannot detect the DCF-signal (for example due to disturbances, trans-
mitting distance, etc.), the time can be set manually. The DCF symbol disappears
and the clock will then work as a normal quartz clock. (see: Manual settings).
Note for radio-controlled time DCF
The time base for the radio-controlled time is a caesium atomic clock operated by the
Physikalisch Technische Bundesanstalt Braunschweig. It has a time deviation of less
than one second in one million years. The time is coded and transmitted from Mainflin-
gen near Frankfurt via frequency signal DCF-77 (77.5 kHz) and has a transmitting
range of approximately 1,500 km. Your radio-controlled clock receives this signal and
converts it to show the precise time. Changeover from summer time or winter time is
automatic. In Daylight Saving Time
reception depends mainly on the geographic location. Normally there should be no
reception problems within a 1,500 km radius around Frankfurt.
Please take note of the following:
• The recommended distance to any interfering sources like computer monitors or TV
sets is at least 1.5 - 2 meters.
• Inside ferro-concrete rooms (basements, superstructures), the received signal is
naturally weakened. In extreme cases, please place the unit close to a window to
improve the reception.
