DCF 77 RADIO CONTROLLED CLOCK
The radio-controlled time is calculated by the Cesium Atomic clock of Braunschweig
(official clock of Germany). Then the time is coded and transmitted from Mainflingen – near
Frankfurt – via a signal on DCF-77 (77.5 kHz). The transmitting range of the signal is 1500 km,
which means that most of Western and Central Europe is covered by this signal.
Within this range the received time is completely accurate. Once sensor signal(s) are
received, the wave icon will flash to indicate that the receiving unit starts to receive
the DCF radio controlled time signal. Radio Controlled wave icon can indicate 4 levels
of signal status:
Very weak Weak Medium Strong
Once the time signal is received, the wave icon will stay on the LCD, and time and calendar will
automatically be updated.
Note: During the 10-minute time signal reception, all manual settings will be suspended.
If setting is desired, press once [ + ] key to deactivate the reception. You can also press
and hold the same key for 2 seconds to manually activate the reception in normal mode.
