BINGO - Radio-controlled alarm clock
• The device will alert you with a beep and all LCD segments will be dis-
played for a short moment.
• The clock will now scan the DCF frequency signal and the DCF sym-
bol will be flashing on the LCD. When the time code is received
successfully after 3-8 minutes, the radio-controlled time, the date and
the DCF symbol are displayed steadily in the LCD.
• The DCF reception always takes place at 3:00 o'clock in the morning.
If the reception is not successfully received at 3:00 o'clock, it shall be
held further attempts at 4:00 and 5:00 o'clock.
• You can also start the initialization manually.
• Press and hold the – button for three seconds.
• The DCF symbol will be flashing.
• To end the reception, press and hold the – button for three
seconds again. The DCF symbol disappears.
• There are three different reception symbols:
flashes - reception is active
stays - reception is good
no symbol - no reception/reception is deactivated
• 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. (see: Manual settings).

BINGO - Radio-controlled alarm clock
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 fre-
quency signal DCF-77 (77.5 kHz) and has a transmitting range of
approximately 1,500 km. Changeover from summer time or winter time
is automatic. In Daylight Saving Time
quality of the reception depends mainly on the geographic location. Nor-
mally there should be no reception problems within a 1,500 km radius
around Frankfurt.
Please take note of the following:

and reception is possible in most cases. A single daily reception is
adequate to keep the accuracy deviation under 1 second.
