Destination Protect
This button is a toggle that sets or clears a protect on the current destination device. 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.
Note: a protect prevents others from routing to a destination; a lock prevents anyone —
even the user who issued the lock — from routing to the destination.
You may lock a protected destination, but you cannot change a locked destination to a
protected destination directly. You must first unlock it.
The NV9649 provides no explicit indication, during operation, whether a destination is
locked or unlocked.
Free Source
The button selects a pre-defined phantom device that can be used to release or "free"
devices on the data (machine control) level. A free source is also used with tielines to free
the tieline for others to use. The actual free source used is defined in the NV9000
configuration.
Use this button as if it were a source button.
Forward
This button displays and activates the next button page of an automatically generated list.
A forward button is never high-tally. A forward button is generated by the system when the
current page of a list has more than 28 or 29 elements. Otherwise, the list is at its last page
and a forward button would do nothing. Forward buttons are always accompanied by
"back" buttons.

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.
Hold
The 'Hold' (a.k.a. 'Hold Preset') button is a toggle. Press it once to activate "hold" mode,
press it again to deactivate "hold. " The button is high-tally when hold mode is active and
low-tally when it is not.
You can activate or deactivate hold mode at any time during an MD selection or a
breakaway selection in X-Y mode. Your selection remains intact and the panel subsequently
operates in hold mode or non-hold mode according to the hold button state.
The default button text is "Hold Preset" but the button can have any legend.
