month, day and day-of-week language and adjust with ▲or ▼ button.
• The time zone is used for countries where the DCF signal can be received, but the time zone is different from the DCF time (e.g.
+1=one hour later).
• Day-of-week language: German (GER), English (ENG), Italian (ITA), French (FRE), Dutch (DUT), Spanish (SPA) and Danish (DAN).
• The manually set time will be overwritten by the DCF time when the signal is received successfully and the symbol appears on the
display.

6. Getting started
• Open the battery compartment and insert two new batteries 1.5 V AA, polarity as illustrated.
• 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, 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 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
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.
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
reception is adequate to keep the accuracy deviation below 1 second.
• The radio-controlled clock receives the signals at 1:00 o'clock in the morning (5 times).
