Operation
Lock, Protect, and Release
Menu
The button puts the NV9601 panel in menu mode and places a small menu on the LCD
buttons, that provides access to a variety of panel options.
By pressing any of the menu buttons, you may enter data (such as panel ID) or change LCD
brightness values or you can view panel data. The LCD button text varies with context in
menu mode.
See Menu Mode on page 55 for more detail.
Name Set Toggle
A ‘Name Set Toggle’ button toggles the panel between its default name set and the “system
name” set. Whichever name set you select becomes the “active” name set.

‘Name Set Toggle’ buttons are disabled while a category selection is in progress.
 The panel requires that category/suffix device selection be performed using the names
in the system name set. However, it displays the device you selected using the active
name set. We recommend that you switch to the system name set prior to cate-
gory/suffix device selection and return to your preferred name set afterward.
Panel Lock
A panel lock button prevents changes to the panel settings, especially router crosspoints.
When the panel is locked, the button array becomes blank except for the ‘Panel Lock’
button which becomes high-tally red.
The button is a toggle: press the ‘Panel Lock’ button to lock the panel. Press it again to
unlock the panel.
Preset Release
This button removes locks and protects from preset source devices. (If source locks and
protects are not used in your system, this button is not needed.)
If you select a source and someone else has locked or protected the source, you can release
it if your panel has “forced release” enabled.
Previous Source
This button presets the previously selected source for the current destination. This function
is useful when you make a route in error.
To recover the previous source, press ‘Previous Source’. When you do, the ‘Take’ button goes
high-tally. Then press ‘Take’ to recover the source.
Protect
This button is a toggle that sets or clears a protect on the current source when the panel is
in source mode or on the current destination when the panel is in destination mode.
The protect can be removed at the panel that originally set the protect, at any panel that
has the same user ID, or by a forced release at any panel.
