Radio-controlled alarm clock
• The DCF reception always takes place daily at 1:00 o'clock in the morn-
ing. If the reception fails, it will repeat again 5 times every hour.
• You can also start the initialisation manually.
• Press and hold the WAVE button for 3 seconds.
• To end the DCF reception attempt, press the WAVE button again.
• There are three different reception states:
flashing – reception is active
solid – reception is very good
no DCF reception
• 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.
Radio-controlled time reception
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 Main-
flingen 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 automat-
ic. In Daylight Saving Time DST is shown on the LCD. The reception quali-
ty 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.
• During night-time, the atmospheric interference is usually less severe
and reception is possible in most cases. A single daily reception is ade-
quate to keep the accuracy deviation under 1 second.
