How to adjust the Light Pipe focus lens?
1. Loosen the adjustment screw of the focus lens (reference 2 Image 10-18) a few turns. Use a 5.5 mm nut
driver. Do not remove the adjustment screw.
2. Start up the projector but do not activate the light source yet.
3. Set up the projector to display a full white internal pattern with a maximum contrast and a maximum
dimming , without activating the light source. Make sure that you have a 5.5 mm nut driver within reach for the
next steps.
4. Activate the light source and zoom the projector lens in or out until the projected image is focused.
Note: Dialog windows must be displayed sharp instead of blurry. This is independent of the focus of
the light beam.
5. Gently move the adjustment screw (reference 2 Image 10-18) of the Light Pipe focus lens UP or DOWN into a
position which projects the sharpest possible edges on the screen ( FOCUS ). Use a 5.5 mm nut driver as an
extension bar of the adjustment screw. This allows a more precise adjustment.
Warning: The adjustment screw of the Light Pipe focus lens is hot. To prevent burn injuries use 5.5mm
nut driver for moving the Integration Rod.
