Using Horizontal Nulling
After entering Image Recall Mode, select one module by pressing its
Select
button. This
module becomes the “Null Controller” and the console is now in Horizontal Nulling
Mode.
To select an item to null, turn the desired knob on the Null Controller. Each module’s
LED display shows the null state of that control on that module. Adjust that knob on
each module until all LEDs on the display are Off.
To null another row of controls, simply turn the desired knob on the Null Controller and
adjust the same knob on all of the modules.
To return to Recall Display mode, deselect all modules.
NOTES:
• Any module may be selected as the Null Controller. Only one module is selected when
using Horizontal Nulling.
• It is not necessary to null items in any particular order.
• It is not necessary to null all items, null only the knobs and switches that you desire.
• To enter Vertical Nulling Mode, simply select more modules.

Vertical Nulling Mode
To enter Vertical Nulling Mode, simply select two or more modules. Vertical Nulling
allows up to 7 Input modules to be nulled simultaneously and independently. As an
operator selects a module item, the LED display changes to show nulling information
about that item. When the operator adjusts another item, the LED display changes to the
new item.
While in Vertical Nulling Mode, only the modules being nulled are active—the LED bar-
graph displays on inactive modules are turned off. (The “Bank Nulled” indicators are
always active.) To select a other modules, the operator must deselect one or more
modules then select the modules desired.
