4.3.1 TIME FUNCTION
The radio controlled time signal (DCF 77) is transmitted from the
central atomic clock in Frankfurt/Main. It has a reception range
of approx. 1500 km. If the (
) tower icon is not fully lit (
), or if
the time and date are not set automatically, please consider the
following:
During night-time hours, atmospheric disturbances are typically
less severe and radio signal reception may improve. A single daily
reception is suffi cient enough to keep the clock accuracy within
1 second.
Make sure the unit is positioned at least 2 meters (8 feet)
