4. Adjust the screw of the lens holder tilt mechanism until the mid top and mid bottom of the projected pattern is most sharp on the
screen. Use a 5,5 mm nut driver or a flat screw driver.
Tip: Use a white paper to search for the "sharp focus plane" at the top or bottom side of the projected pattern. Turn the
adjustment screw a bit and check if the sharp focus plane has come closer to the screen. If not, turn the adjustment
screw in the opposite direction and check again.
Note: A simultaneous readjustment of the focus shift plate will be necessary to get the mid top and mid bottom of the projected
pattern equally focused as the centre.
