Needs System Jam
This flashing display indicates that the
Lock Control
menu item is set
to
slow lock
and there has been a large change in the Frequency
reference (e.g. a sudden phase in the phase of the video reference).
In order for the 5600MSC to lock to its frequency reference input it
must perform an abrupt lock that will affect the complete system
timing of the 5600MSC. In order to perform the System Jam, press
the
INPUT
button to access the
Force System Jam Menu
item. When
a system jam is needed, any leds that are on, will be flashing. See

display is showing 100% and the input frequency reference is
10/5MHz, GPS, or Video in narrow range. If the input is Video, and
the 5600MSC cannot lock, the range should be set to wide.
