COLORS ARE NOT CORRECT
1. Try resetting factory defaults (ON-40-ENTER).

W.G. is selected. Wait 10 sec. Press IRIS to return.

PERIODIC LOSS OF CONTROL

TO SEE SUBJECT
•
Turn on backlight compensation (ON-20-ENTER).
PICTURE IS ROLLING, NOISY, OR
DISTORTED
•
Electronic AC power line noise may distort the picture and cause loss of Sync.
If the picture is distorted, try switching to Internal Crystal (OFF-42-ENTER).
If this corrects the picture problems, there may be excessive line noise on the
power supply.
