Radio-controlled alarm clock
with thermometer
• The time base for the radio-controlled time
is a Caesium Atomic Clock operated by the
Physikalisch Technische
Braunschweig which 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 transmit-
ting 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:
• Recommended distance to any interfering
sources like computer monitors or TV sets is
a minimum of 1.5 - 2 metres.
• Within ferro-concrete rooms (basements,
superstructures), the received signal is nat-
urally weakened. In extreme cases, please
place the unit close to a window and/or
point its front or back towards the Frank-
furt transmitter.
• During night-time, the atmospheric distur-
bances 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.
7. Operation
• Important: Buttons will not function while
scanning for DCF unless they are well
received or stopped manually.
• The instrument will quit automatically the
setting mode, if there is no button used
within 8 seconds.
