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. However, there are many environment factors may affect the RCC
reception, i.e. nearby computer monitors or other electronic devices, put on any metal surface, surrounded by any
tall buildings and so on. The user had better to place the atomic clock near the window and face the transmitter in
Mainflingen-near Frankfurt, Germany. And then check the RCC strength indicator in the clock display to see if there has
any wave above the reception tower. There have 3 wave icons flash to indicate 4 levels of RCC signal status:
Very weak
If there has no wave above the reception tower that means the signal is very weak and the clock can not be set by
the RCC signal, please try to rotate the unit or other windows to seek for a better RCC reception location. Besides,
the RCC signal is the strongest at night, the user can manually set the clock to locale time and leave it overnight to
receive the RCC signal.
If nothing else works, take the clock outdoors after dark at night, remove and re-install the batteries and leave it
overnight to force it to look for the radio controlled time signal. If the clock works outdoors but not indoors, you
probably have a local interference problem inside your house or building.
Once the time signal is received, the wave icon will stay on the LCD, and time and calendar will automatically be
updated.
Note: During 10 minutes of time signal reception, all ma nual settings w ill be suspended. If setting
is desired, press once [ ] key to deactivate the reception. You can also press and hold the
same key for 3 seconds to manually activate the reception in normal mode. The clock will work as
a normal quartz clock if it can't receive the RCC signal.
