2)
The external synchronization to the RADIO CLOCK has not
supplied a signal for more than 30 minutes (default setting),
and a switch has not yet been made to a substitute
synchronization.
1) If the display flashes, no valid signal is currently being received.
2) This occurs when the timeout selected for switching to the substitute
synchronization is longer than the monitoring timeout for the external
synchronization.
The timeout for switching to the substitute synchronization can be set with the
following parameter entry:
/Redundancy/Redundancy/Timeout (0.09.10)
The timeout for the external synchronization can be set with the following
parameter entry:
/Inputs/Input 1/Monitoring/Timeout (0.20.01)
