Radio-controlled alarm clock
with thermometer
• The time base for the radio-controlled time is a Cae-
sium Atomic Clock operated by the Physikalisch
Technische Bundesanstalt Braunschweig which has
a time deviation of less than one second in one mil-
lion years. The time is coded and transmitted from
Mainflingen near Frankfurt via frequency signal
DCF-77 (77.5 kHz) and has a transmitting range of
approximately 1,500 km. Your radio-controlled
alarm clock receives this signal and converts it to
show the precise time in summer or wintertime. In
Daylight Saving Time "DST" is shown on the LCD.
• The quality of the reception depends greatly on the
geographic location. In normal cases, 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 a min-
imum of 1.5 - 2 metres.
• Within ferro-concrete rooms (basements, super-
structures), the received signal is naturally weak-
ened. In extreme cases, please place the unit close
to a window and/or point its front or back towards
the Frankfurt transmitter.
• During night-time, the atmospheric disturbances
are usually less severe and reception is possible in
most cases. A single daily reception is adequate to
keep the accuracy deviation below 1 second.
