Using Test Patterns
rëáåÖ=qÉëí=m~ííÉêåë
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.

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.
