4. Getting started
• Insert a new battery 1,5 V AA, ensure that the battery polarity is correct.
• The device is ready for use.
4.1 Reception of the DCF frequency signal
• The clock's hands move to 12 o'clock.
• The clock will now scan the DCF frequency signal
• When the time code is received successfully after 3-12 minutes, the
radio-controlled time is displayed steadily on the display.
• The DCF reception always takes place daily at 1:00 and 3:00 o'clock in
the morning.
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 Mainflingen near Frankfurt via fre-
quency signal DCF-77 (77.5 kHz) and has a transmitting range of approx-
imately 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. The quality of the 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.
• During night-time, the atmospheric interference is usually less severe
and reception is possible in most cases. A single daily reception is
adequate to keep the accuracy deviation under 1 second.
4.2 MSET button - Manual setting of the clock
• If the clock cannot detect the DCF-signal (for example due to distur-
bances, transmitting distance, etc.), the time can be set manually. The
clock will then work as a normal quartz clock.
• Press and hold the MSET button for three seconds.
• Press and hold the MSET button until the desired time is indicated.
• Press the button briefly the clock's hands will move minute by minute.
• The clock's second hand stops at 12 o'clock.
• After 15 seconds, the clock's second hand will move forward again.
• The manually set time will be overwritten by the DCF time when the
signal is successfully received.
4.3 REC button
• Manual initialization can be helpful.
• Press and hold the REC button for three seconds.
