2. Rotate the focus shift plate of the lens holder until the centre (F) of the projected pattern is most sharp on the screen.
Tip:
Use a white paper to search for the “sharp focus plane”. The sharp focus plane is located behind the screen in case you
can’t focus the projected pattern on the paper somewhere between the screen and the lens. Knowing that will help you
to determine in which direction you have to rotate the focus shift plate. Rotate the plate counterclockwise in case you
can’t
fi
nd the sharp focus plane somewhere between screen and lens.
Tip:
Immediately fasten the three screws of the lens holder front plate in case of using a projection lens which is to heavy for
the three retaining springs of the lens holder plate.

3. Adjust the screw (bit by bit) of the lens holder swing mechanism until the mid left and mid right of the projected pattern is most
sharp on the screen. Use a 5,5 mm nut driver or a
fl
at screw driver.
Tip:
Use a white paper to search for the “sharp focus plane” at the left or right 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 left and mid right of the projected
pattern equally focused as the centre.

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
fl
at 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.
