Operation
Button Functions
 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.
MD Mode
In MD mode, turning hold mode on allows you to select more than one destination button at a
time. When you select a source, the source applies to all selected (high-tally) destinations. If hold
is still on when you press ‘Take’, the selected destinations remain selected and the display
reflects the selected destinations. The buttons for the selected destinations remain high-tally.
Without hold enabled, the panel has no destinations selected after an MD take and the buttons
for the selected destinations go low-tally.
When hold is active, all selected MD destinations get the source you selected most recently (in
case you change your mind and selected another source).
