BINGO 2.0 - Radio-controlled alarm clock
BINGO 2.0 - Radio-controlled alarm clock
• If the clock cannot detect the DCF-signal (e.g. due to interferences,
transmitting distance, etc.), the time can be set manually. The clock
will then work as a normal quartz clock. (See: Manual settings).
Radio-controlled time reception
The time base for the radio-controlled time is a caesium atomic clock
operated by the Physikalisch Technische Bundesanstalt in Braun-
schweig. It has a time deviation of less than one second in one million
years. The time is coded and transmitted from Mainflingen near Frank-
furt via frequency signal DCF-77 (77.5 kHz) and has a transmitting
range of approximately 1.500 km. Changeover from summer time to
winter time is automatic. In Daylight Saving Time, DST is shown on the
LCD. The quality of the 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
screens or TV sets is at least 1.5 - 2 meters.
• Inside concrete rooms reinforced with steel (e.g. basements, super-
structures), the received signal is naturally weakened. In extreme
cases, please place the unit close to a window to improve the recep-
tion.
6. Getting started
• Open the battery compartment and insert the three AA 1.5 V batteries.
Make sure the polarities are correct.
• Close the battery compartment again.
• The device will alert you with a beep and all LCD segments will be
displayed 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 success-
fully received after 3-8 minutes, the radio-controlled time, the date
and the DCF symbol are steadily displayed on the LCD.
• The DCF reception always takes place at 3:00 o'clock in the morning.
If the reception is not successfully received at this time, further
attempts will happen at 4:00 and 5:00 o'clock respectively.
• 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:
flashing - reception is active
solid - reception is good
no symbol - no reception/reception is deactivated
