If there are blurred lines of pixels or some pixels flickering, an adjustment of the
video transmission path on the transmitter side may be necessary.
How to proceed:
1. Check cabling for loose connection before adjusting the video
transmission path since faulty cabling may also cause interferences.
2. Switch on all devices and wait for approx. five minutes for the devices to
reach their operating temperatures.
3. Turn the adjustment screw 1 counterclockwise for at least 20 revolutions
to ensure that the potentiometer has reached its left limit stop.
The display may not be showing any picture at all anymore (connection
aborted).
4. Turn the adjustment screw 1 clockwise until all interferences are gone.
If, even after several revolutions, no picture is displayed, switch off the
connected display unit and then switch it on again.
5. Keep on turning the adjustment screw clockwise until interferences occur
again. Please count the number of revolutions.
6. Now turn back the adjustment screw for half of the revolutions you
counted.
