Radio-controlled alarm clock
• 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 clock will then work as a
normal quartz clock. (see: Manual setting of the clock and calendar).
Radio-controlled time reception
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 frequency signal DCF-77 (77.5 kHz) and has a trans-
mitting range of approximately 1,500 km. 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 metres.
• 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 recep-
tion is possible in most cases. A single daily reception is adequate to keep the
accuracy deviation under 1 second.

• The manually set time will be overwritten by the DCF time when the signal is
received successfully.
7.2 Setting of the time zone
• The time zone setting is needed for countries where the DCF signal can be
received but the time zone (+12/-12) is different from the German time (e.g.
+1=one hour later).
