Condition 2
: A source is currently showing on the output.

When you select a new source, the system transitions to black.
Once the “auto acquire” of the new source is complete, the
system transitions to the source.
~
Condition 3
: A test pattern is showing on the output.
•
When you select a new source, the system transitions the test
pattern off, and then follows the rules outlined for conditions 1

Pressing the
TEST PAT
button selects the internal test pattern as the ACS-2048’s source.
There are two ways to use the button:
•
When
TEST PAT
is pressed, the button lights, and the internal test pattern is
routed to the output. When you select another input, the system transitions to the
new input.
•
When the
TEST PAT
button is already lit, press the
TEST PAT
button again to
toggle back to the last selected input.
Please note the following important points regarding test pattern usage:
•
When
Menu Context
is
ON
and
TEST PAT
is pressed, the last selected test
pattern is automatically enabled, and the Type field is selected, enabling you to
change patterns easily.
•
If you need to change the state of the Raster Box in this mode, press
ESC
, scroll
to the
Raster Box
field, and change the function as required.
•
Regardless of the
Menu Context
mode, pressing
TEST PAT
has no effect on the
state of the Raster Box. It always remains in its last selected mode.

PAT
Note
If the
Menu Context
mode is
ON
in the
User Preference
Menu
, the
Test Patterns Menu
appears whenever the
TEST
PAT
button is pressed, allowing you to select an internal test
pattern and adjust additional test pattern parameters.
