• Press and hold the button for 3 seconds. The DCF symbol will be flashing.
• Interrupt the reception by pressing the button again. The DCF symbol disappears.

just tower - RCC function ON
no reception
There are four different reception symbols:
flashing - reception is active stays - reception is very good
• If the clock cannot detect the DCF-signal (for example due to disturbances, transmitting distance,
etc.),the time can be set manually. The DCF symbol disappears and the clock will then work as a
normal quartz clock.(see: Manual settings).
• If do not need DCF,it can turn off the function.(see:Manual settings).
no symbol - RCC function OFF
time is manually set
-8-
• The DCF reception always takes place hourly between 2:00 and 5:00 o'clock in the morning. If the
reception is not successfully received until 5:00 o'clock, the next receive operation is again at 2:00
o'clock in the morning.
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.Your radio-controlled clock receives
this signal and converts it to show the precise time. Changeover from summer time or winter time is
automatic. In Daylight Saving Time "DST" 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.
6.3.1 Note for radio-controlled time DCF

Please take note of the following:
• The recommended distance to any interfering sources like computer monitors or TV sets at least
1.5-2 meters.
• 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 reception.
• During night-time, 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 under 1 second.
• During the operation, all successful settings will be confirmed by a brief beep tone.
• The device will automatically quit the setting mode if no button is pressed for a long period of time.
• Press and hold the or button in the setting mode for fast running.

• The weather forecast relates to a range of 12 hours and indicates only a general weather trend. The
accuracy is about 70 %.
• For example, if the current weather is cloudy and the rain symbol is displayed, it does not mean the
product is faulty because it is not raining. It simply means that the air pressure has dropped and the
weather is expected to get worse but not necessarily rainy. The accuracy is about 70 to 75%.
• The sun symbol also appears at night if there is a starry night.
