Centering Adjustment
The three colors, red, green and blue, must converge for proper projection.
If you move the projector to another location, you have to perform the
centering adjustment.
The following are the procedures for using a built-in test pattern.
You can also perform the centering adjustment using an external test signal
without displaying a test pattern. To use an external signal, change the
CENT ADJ setting on the SYSTEM PRESET page. (See page 17.)
1 Press down the MAIN POWER switch of the projector.
2 Turn on the power by pressing the 1/u button.
3 Press the R CENT button.
The built-in cross hair test pattern is displayed and you can adjust the
red lines.
