applying pressure to unsnap it from the lens. Also, a circular cowl rests on the
lower cover and it must be removed. Neither of these items will be reinstalled.

Assembly:
1. If you are installing a Navitar MCZ275, the adapter is an integral lens
component and you will use the three (3) screws provided with your Navitar
lens to attach the lens to the projector. This lens is now installed and the
projector cover and lamp cover may now be reinstalled. To adjust the zoom
and focus, twist the knurled inner ring to zoom and the knurled outer ring to
focus the lens.
2. All other lenses (MCL1028, MCZ500, MCZ900) use an adapter that may be
removed from the lens. Remove the adapter from the lens and install it on the
projector using the three (3) screws provided with your Navitar lens.
3. Install the Navitar lens into the adapter by gently turning it clockwise into the
lens mount. The lens should now be properly installed.
4. To focus, gently twist front of lens. To zoom, loosen the thumbscrew and
twist knurled ring but ensure you re-tighten the thumbscrew. CAUTION: Do
not twist entire lens out of mounting bracket!
