INSTALLATION & SETUP
Step 4
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
RECALL 9 then 0 . (Recall memory
numbers may be any number from 01 to 99. lf the selected Recall memory did not
previously exist, it will be created automatically.
Step 2
Press UTIL 1 then 6 to access the Internal Frequency Selection menu. Items one to six
contain preset scan frequencies covering the scan range of the projector. It is
recommended that Recall memories be created for each. To make a selection, enter an
item number or use
UP and DOWN to move the cursor bar to the item you want, and
then press ENTER.
Tip: It is recommended that Recall memories for the two extreme frequencies be set up
first (items 1 and 43).
When other Recall memories are created, their initial display settings will be based on
the settings already stored in memory.
Step 3
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
EXIT while only the test
pattern is displayed.
