INSTALLATION AND SETUP
STEP 4Pull lens assembly out
Carefully pull the lens assembly straight out of the projector
and set aside.
STEP 5Install new lens assembly
IMPORTANT:Remove the rear (smallest) lens cap from the new
lens. Make sure the front lens cap remains on during installation.
Align the large cut-out area on the lens flange to the bottom of the
lens mount (which has a matching cut-out). The 3 lens assembly slots
should align with the lens mount screws so that the screw heads will fit
through the large end of the slots (see Orientation figure).
NOTE: On most lenses, a small extra “keying” slot located at approxi-
mately 2 o’clock on the lens flange will align with a set screw in the same
location on the lens mount, preventing the lens from being installed in the
wrong orientation. If the lens flange does not seem to fit into place over all
screws, try rotating the lens assembly in one direction or another.
With the lens assembly aligned and the screws inserted through the flange, use both hands to
rotate the lens barrel clockwise until the lens mount screw heads lock into the small end of the
lens assembly slots.
Secure the 3 lens mount screws.
STEP 6Reposition the projector for new lens
Remove the front lens cap and reposition the projector closer or further from the screen as nec-
essary for the screen and the new lens type (refer to Throw Distance section 2.6). In a permanent
installation, always use the appropriate throw distance formula to calculate the distance accurate-
ly Power up and test. Adjust offsets as necessary.
