Radio-controlled alarm clock
5. Radio-controlled time reception
• The clock hands move to 3.00 o'clock. 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 and
the DCF symbol will be shown steadily on the display.
• You can also start the initialization manually.
• Press and hold – button for three seconds.
• The DCF reception symbol will be flashing.
• Interrupt the reception by pressing the – button again for
three seconds. The DCF reception symbol disappears.
• The DCF reception always takes place daily at 2:00 o'clock
in the morning. If the reception is not successfully re-
ceived, the next DCF reception attempt will happen at 3:00
o'clock in the morning.
• If the clock cannot detect the DCF-signal (e.g. due to inter-
ference, transmitting distance, etc.), the time can be set
manually. The clock will then work as a normal quartz
clock.

Radio-controlled alarm clock
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 adjust-
ment to Daylight Saving Time (summer/winter time) is automa-
tic. In Daylight Saving Time the DST symbol is shown on the
display.
Therefore, please note the following steps:
• The recommended distance to any interfering sources like
computer screens or TV sets is at least 1.5 - 2 meters.
• Within concrete walls (reinforced with steel) such as base-
ments, the received signal is naturally weakened. In
extreme cases, please place the unit close to a window to
improve reception.
