Navitar/NuView Series 648 lens on 3M X70 & X80 projectors.  
 
TOOLS REQUIRED: FLAT HEAD SCREWDRIVER 
 
Disassembly: 
 
1.  Disconnect unit from power source and place projector with lens facing up. Remove two 
(2) screws from bottom cover of lens. Remove cover and set aside for reinstallation.  
 
2.  Remove prime lens by depressing the lever on the left side of the prime lens and rotating

Assembly: 
 
1.  Ensure that your Navitar lens and its adapter are separate (except on MCZ275). Position 
the adapter with the ‘up’ label in the correct position and slide the adapter into the 
projector ensuring proper engagement. Rotate the lever counterclockwise until the 
adapter is securely in place.  
 
2.  Replace the front cover of the projector removed in step 2, above. 
 
3.  Install the lens by gently rotating clockwise as it is inserted into the adapter. 
 
To focus, gently twist the front of lens.  To zoom, loosen thumbscrew and 
twist knurled ring (zoom lenses only, of course).  Re-tighten thumbscrew.  
CAUTION: Do not twist entire lens out of adapter! ON MCZ275 models twist 
the inner knurled ring to zoom and twist the outer knurled ring to focus the 
lens.
