STEP 3 Rotate the lens
Rotate the lens counter-clockwise until
the tabs are free from the lens retainer
ring. See Figure 4.10A.
NOTE: The connector slide assembly
allows the connector to move as the

Pull lens out
Lens connectors will disconnect when
you pull the lens straight out from the
projector. See Figure 4.10B.

Electrical connector: Line up male connector on the lens with the female
connector on the connector slide assembly.
• Insert lens: Align the tabs on the lens plate lock with the slots in the lens
retainer ring. Push the lens in approximately ½ inch.

Rotate the lens: Rotate the lens clockwise until the tabs are tightly secured and
the lens release button CLICK.
• Secure lock-down screws
(optional): For added stability,
secure the adjustment screws
provided on the lens-retaining ring
(see Figure 4.11). If you have
installed a large zoom lens, one or
more of the screws may be
inaccessible—simply tighten those
that are accessible (Figure 4.12).

lenses such as 0.73:1 and 1.2:1.
STEP 5
Power Up
Remove the lens cap and power up the
projector.
STEP 6 Reposition the Projector for New
Lens
Reposition the projector closer or further
from the screen as necessary for the screen
and the new lens type – refer to lens
descriptions in Section 2, Section 6 and
Appendix D, Throw Distance. In a
permanent installation, always use the appropriate throw distance formula to calculate
the best position for the projector.
