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's 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's
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, transmitting dis-
tance, etc.), the time can be set manually. The DCF symbol disappears and 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 Mainflingen 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 reception depends mainly on the geographic location.
Normally 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
at least 1.5 - 2 metres.
• Inside ferro-concrete rooms (basements, superstructures), the received signal is naturally
weakened. In extreme cases, please place the unit close to a window to improve the recep-
tion.
• During nighttime, the atmospheric interference is usually less severe and reception is possi-
ble 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 se-
conds.
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.
• Hold the button until the desired time is indicated.
• Press the button briefly the clock's hands move minute by minute.
• The manually set time will be overwritten by the DCF time when the signal is received suc-
cessfully.
Radio controlled alarm clock
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).
• When the alarm time is reached, the alarm will ring for 2 minutes.
• If it is not stopped, the alarm will automatically turn off after 2 minutes and will be reactivat-
ed at the same time.
• When the alarm rings, press SNOOZE/LIGHT button and the snooze function is activated. The
backlight turns on for a short time.
• The alarm will be interrupted for 5 minutes.
• The snooze function can be activated up to seven times.
• Move the ON/OFF switch downwards (OFF), the alarm function is deactivated.
7.3 Display of seconds and date
• Once the reception of the DCF time is successful press M.SET button to toggle between the
display of seconds and date:
• Display of date: Press the REC button to toggle between M/D month/day sequence (Ameri-
can version) or D/M day/month (European version).
Attention:
If there is no DCF reception possible only the seconds appear on the display.
