• All other information disappears from the display. During the DCF
time reception period, no button can be pressed.
• When the time code is successfully received after 3-10 minutes, the
radio-controlled time, the date and the DCF symbol will be shown
steadily on the display.
• The indoor temperature, the humidity and the corresponding smiley
symbol appear on the display.
• Interrupt the reception by pressing the SET button for 3 seconds.
• The DCF reception always takes place daily at 1:00, 2:00 and 3:00
o'clock in the morning. If the reception is not successfully received,
another DCF reception will take place the next full hour (up to
2 times).
• You can also activate the DCF reception manually. Press the SET but-
ton. The DCF reception symbol flashes.
• If the clock cannot detect the DCF-signal (e.g. due to interference,
transmitting distance, etc.), the time can be set manually. The DCF
reception symbol disappears and the clock will then work as a nor-
mal quartz clock (see: Manual settings).
• Once the DCF time signal is successfully received and the DCF
reception is activated (dcF ON), the manually set time is overwritten.

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 Braun-
schweig (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 auto-
matic. The reception quality depends mainly on geographic location.
Normally there should be no reception problems within a 1,500 km
radius around Frankfurt.
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 basements, the
received signal is naturally weakened. In extreme cases, please place
the unit close to a window to improve reception.
