Locks
Performing locks in a network is almost the same as performing locks for a stand-alone CR6400.
However, please note:
• Pressing ‘Panel Lock’ locks that panel and no other.
• A destination lock locks a destination on all selected levels. The lock state of a destination is
not changed on unselected levels.
If all the selected levels of a destination are locked, the destination button is red. If some of
the selected levels of a destination are unlocked, the destination button is amber.
• A destination locked at one control panel cannot be unlocked at another control panel.
 Be sure to unlock any locks before removing a panel from a network!
• Locks can be released using CRSC.
As previously stated, two of the function buttons are locks and four are level buttons. Two others
are destination mode and source mode.
This illustration shows a system that has 3 levels (1–3), two of which are selected. Buttons for
selected levels are high-tally. The button for (non-existent) level 4 is dark.
Panel Lock
Pressing ‘Panel Lock’ disables the control panel on which you press ‘Panel Lock’. Only the ‘Panel
Lock’ button remains enabled. Pressing it again re-enables the control panel.
When the control panel is locked, the Panel Lock button is bright red and the state of the entire
control panel is protected. Changes from the control panel are disabled. The ‘Panel Lock’ button
is low tally green when the control panel is not locked.
 Remember that a ‘Panel Lock’ button locks that panel only. It does not lock any router, other
control panels, or the network.
Destination Lock
Destination lock prevents an operator from selecting another source for the currently selected
destination. In a network, sources and destinations comprise one or more levels. When you lock
a destination, it is locked on the levels you select. And when you unlock a destination, it is
unlocked on the levels you select.
