6. Getting started
• Open the battery compartment and insert a new battery (1,5 V AA), ensure battery
polarity is correct.
• A brief beep tone will sound and all segments will be shown for few seconds.
• The unit is ready for use.
• The clock hands move to 12 o'clock and the clock is trying to receive the radio signal
for 3 - 12 minutes.
• 00 appears on the display and the radio signal symbol flashes.
• When the time code is received, the radio-controlled time will be shown and the
seconds appear on the display.
• The radio signal symbol appears.
• Twelve times a day receives the clock the radio signal.
• Manual initialization can be helpful. Press and hold REC button for 3 seconds. The
clock hands move to 12 o'clock and the clock is trying to receive radio signal again.
• If the clock cannot detect the DCF-signal (for example due to disturbances, transmit-
ting distance, etc.), the time can be set manually. The DCF symbol disappears and
Kat. Nr. 98.1040 the clock will then work as a normal quartz clock. (see: Manual setting of the time).
6.1 Radio-controlled time reception
The time base for the radio-controlled time is a caesium atomic clock operated by the
Physikalisch Technische Bundesanstalt Braunschweig. It has a time deviation of less
than one second in one million years. 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 1,500 km. Changeover from summer time or winter time is
automatic. In Daylight Saving Time "S" is shown on the LCD. The quality of the recep-
tion depends mainly on the geographic location. Normally there should be no recep-
tion 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 at least 1.5 - 2 metres.
• Inside ferro-concrete rooms (basements, superstructures), the received signal is nat-
urally weakened. In extreme cases, please place the unit close to a window to
improve the reception.
• During nighttime, the atmospheric interference is 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
• The instrument will automatically quit the setting mode if no button is pressed
within 8 seconds.
7.1 Manual setting of the time
• Press and hold M.SET button for three seconds.
• The radio signal symbol disappears and the indication of seconds stops.
Kat. Nr. 98.1040

Radio controlled alarm clock

• The manually set time will be overwritten by the DCF time when the signal is
received successfully.
7.2 Setting of the alarm time
• Turn the dial for the alarm time and set your respective alarm time (in direction of
the arrow).
• To activate the alarm function, move the switch ON/OFF upwards (ON).

• If it is not stopped, the alarm will automatically turn off after 2 minutes and will be
reactivated at the same time.
• When the alarm rings, press SNOOZE/LIGHT button and the snooze function is acti-
vated. The backlight turns on for a short time.

between the display of seconds and date:
