and press the ‘Destination Protect’ button to unprotect them. A protected level has a “P” next to it
when it appears in the display.
Free Source
This button selects a phantom device that can be used to release or “free” devices on the data (con-
trol) level. A free source can also be used with tielines to free the tieline for others to use.
Use it as if it were a source.
(The actual free source is configured in the
Level Set Details
page of NV9000-SE Utilities.)
The default button text is “Free Source” but the button can have any legend.
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.
.
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 selec-
tion 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).
X-Y Mode
In X-Y mode, the hold button causes breakaway levels to be retained after a take. The levels you
selected (and deselected) remain lit (or unlit) as they were before the take.
