Instruction Manual

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 RCC-signal (for example due to disturbances, transmitting distance,
etc.),the time can be set manually. The RCC symbol disappears and the clock will then work as a
normal quartz clock.(see: Manual settings).
• If do not need RCC ,it can turn off the function.(see:Manual settings).
no symbol - RCC function OFF

-8-
• The RCC 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.
