Other kinds of buttons can cause the display of a target page. These include ‘Global Navigate’
buttons and category buttons. In practice, navigate buttons, global navigate buttons, and cate-
gory buttons are nearly indistinguishable, although the pages they display can be quite
different.
Global Navigate
A ‘Global Navigate’ button functions the same way a navigate button does. Global navigate
buttons exist mainly for the convenience of the configurer. Operators should rarely notice any
difference between global navigation buttons and other navigation buttons.
Global navigate buttons, however, access only static button pages. They do not access list
pages. That is because configurers have no list options for global navigate buttons.
P Panel Lock
A panel lock button prevents accidental changes to the panel settings, especially router cross-
points. 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: pressing the ‘Panel Lock’ button
again reverts the panel to its previous state.
The button text is either “Panel Lock” or “Panel Unlock.”
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, your panel will illu-
minate the ‘Preset Release’ button and tell you who locked or protected the source. You can
release it if your panel has “forced release” enabled. (Note that you cannot lock or protect
sources with the NV9641A.)
Press the ‘Preset Release’ button to release the source.
The default button text is “Preset Release” but the button can have any legend.
P 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.
 The button does not restore the previous destination. If you have changed the destination
and press ‘Previous Source’, the take will not restore the previous route.
The default button text is “Previous Source” but the button can have any legend.
P Quick Source
A quick source button selects a source and performs an immediate take.
Quick source and source buttons are similar, except that the quick source performs a take. Be
aware of which buttons are quick sources so you do not perform an accidental take. (A quick
source button is always high-tally.)
The button text is the source device’s mnemonic, but the button can have any legend.
