PROJECTION CONFIGURATION CHANGE
Scan Reversal
You will have to reverse the horizontal, vertical and convergence polarity when changing the projector’s configuration.
To reverse the scan, proceed as follows:
CAUTION: Always disconnect the projector from the AC source before reversing the plug. Failure to observe this precaution may
result in electric shock or damage to the projector.
1
Open the top cover.
• See Opening Top Cover section.
2
Reverse the vertical and horizontal scan.
• To reverse the scan there are two sets of plugs on the sweep board. VR, VG and VB are the vertical connectors(V=vertical and
RGB=color) and HR, HG and HB are the horizontal connectors(H=horizontal and RGB=color).
Remove the plug and turn it 180 degrees, then reinstall. Do this for all three of either horizontal or vertical connectors depend-
ing upon your application (See Table below)
