3. Getting started
• Open the battery compartment and insert two new batteries 1.5 V AA, polarity as illus-
trated.
• A short beep will sound and all LCD segments will light up for about 2 seconds.
• The unit is now ready to use.
• The clock will scan the DCF frequency signal and the DCF symbol flashes on the LCD.
When the signal is received successfully after 3-5 minutes, the radio controlled time and
the DCF symbol appear permanently.
• Manual initialization can be helpful. Press
WAVE
button. Press
WAVE
button again to
stop the initialization and the DCF-reception symbol disappears.
• In case the clock cannot detect the DCF-signal (for example due to disturbances, transmit-
ting 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 approxi-
mately 1,500 km. Your radio-controlled clock receives this signal and converts it to show the
precise time in summer or wintertime. 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.
