Make display adjustments as required. Adjustment changes will automatically
be saved in the Recall memory.
ASI Improvement
If the projector will be used with many sources, or new sources will be
frequently added to the system, it is recommended that five or six setup
memories be created expressly for the purpose of improving ASI accuracy.
ASI accuracy improves as more setup memories are created and stored, and the
variations amongst horizontal and vertical scan frequencies increases. For
example, if you always use the same input and you never use Recall memories
(thus only one setup memory has ever been created), ASI will not be effective.
However, if many Input and Recall memories have been used and adjusted for
a variety of sources, the projector has more "knowledge" in its database for
performing an ASI. As this "knowledge" increases, ASI accuracy improves.
An easy way to add setup memories at various scan frequencies is to use the
projector's internal frequency generator. The internal frequency generator can
display a test pattern using the scan frequencies you select. When display
adjustments are made, the display settings are stored in the current setup
memory. Prepare a Recall memory using the generator as follows:
Step 1
Select a Recall memory to be the current setup memory. For example, to
make Recall memory 90 the current setup memory, press l=]
1~]a.
(Recall
memory numbers may be any number from 01 to-99). If the selected Recall
memory did not previously exist, it will be created automatically.

covering the scan range of the projector.

Tip: It is recommended

be set up firsr (items 1 and 4).
When orher Recall memories are created, their initial display settings will be
based on rhe serrings already srored in memoty.

At this point, a test pattern is displayed. Make display adjustments as
required. All display settings will be stored in the Recall memory. To create
another Recall memory, repeat the above steps. To return to the external
source, press ~
