Radio-controlled alarm clock
with thermometer
• The time base for the radio-controlled time is a
Caesium Atomic
Physikalisch Technische Bundesanstalt Braun-
schweig 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 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 Day-
light 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
minimum of 1.5 - 2 metres.
• Within ferro-concrete rooms (basements, super-
structures), the received signal is naturally
weakened. 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 ade-
quate to keep the accuracy deviation below 1
second.
7. Operation
• Important: Buttons will not function while scan-
ning for DCF unless they are well received or
stopped manually.
• The instrument will quit automatically the set-
ting mode, if there is no button used within 8
seconds.
