
Rotate the lens: To ensure the lens is secured in the lens mount, turn it clockwise
until you feel the tabs on the lens butting against the end stops on the lens mount
retaining ring. To ensure the locking
pin is properly engaged, turn the lens
counter-clockwise. If the lens does not
turn counter-clockwise, the locking pin
is properly engaged. If the lens turns
counter-clockwise, the locking pin is
not properly engaged; in this case, turn
it clockwise and pull the lens plunger
assembly out until the plunger
assembly stops. Recheck by turning
the lens counter-clockwise. The lens
should not rotate.
 Secure stability screws
(optional): For added stability,
secure the adjustment screws
provided on the lens retaining ring
(see Figure 4.12). If you have
installed a large zoom lens, one or
more of the screws may be
inaccessible—simply tighten those
that are accessible.
NOTE:
Recommended
lenses such as 0.73:1 and 1.2:1.

Reposition the Projector for New Lens

Reposition the projector closer or further from the screen as necessary for the screen

permanent installation, always use the appropriate throw distance formula to
calculate the best position for the projector (Figure 4.13).
