Radio controlled alarm clock with thermometer
• The clock automatically receives every day at 3:00 in the morning a
radio signal. If the reception fails, the symbol disappears and scan-
ning stops and will be repeated at 4.00 h, 5.00 h and 6.00 h.
• Manual initialization can be helpful. Press and hold
12/24 button at the same time. The reception icon flashes.
• If the reception fails, the symbol disappears and scanning stops and
will be repeated in the next four hours (four times).
• Press and hold the °C/°F and 12/24
to stop the initialization and the DCF-reception symbol disappears.
• In case the clock cannot detect the DCF-signal (for example due
to disturbances, transmitting distance, etc.), the time can be set
manually. The clock will then work as a normal quartz clock. (see:
Manual setting of clock and calendar).
Radio controlled time reception:
The time base for the radio controlled time is a Caesium Atomic Clock
operated by the Physikalisch Technische Bundesanstalt 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 transmitting range of
approximately 1500 km. The time is coded and transmitted from Main-
flingen near Frankfurt via frequency signal DCF-77 (77.5 kHz) and has a
transmitting range of approximately 1500 km. Your radio-controlled 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.

Radio controlled alarm clock with thermometer
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, superstructures), 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 recep-
tion is adequate to keep the accuracy deviation under 1 second.
7. Operation
• Important: Please do not press any buttons during signal reception.
• During operation, all successful settings will be confirmed by an
acoustical signal.
• The instrument will quit automatically the setting mode, if there is
no button used within 8 seconds.
• Hold °C/°F or 12/24 button you will enter fast mode.
