Front panel PZF509
Pilot lamps
The 'Feld'-LED is switched on if a DCF-signal with at least minimum field strength
needed for the correlation receiption is detected at the input of the receiver.
The 'Syn.'-LED indicates that the autocorrelation coefficient decreases beyond 52%
and correct receiption is not possible therefore. This happens if a strong interferer
within the bandwidth of the receiver is present or the transmitter is switched of.
If the 'Freil.'-LED is on, it was not possible to synchronize the internal realtime clock
to DCF-time. This condition occures for at most two minutes after switching on the
PZF509, because two DCF-telegrams are checked for plausibility before the data is
taken over. Short disturbance of receiption can cause this state too.
Display
The eight digit alphanumeric display shows important information concerning
status and time. The setting of system parameters is also done with the help of the
display.
Control keys
It is possible to change the displayed information (time, date or status information)
by two keys. The 'Menu'-key selects one of several menus. After presing the
'Set'-button the belonging information appears on the display. Furthermore, the keys
are used to set user-specific parameters in several submenus.
