a variety of lenses can accommodate different throw distances and specific types of installations. see page 6-1 for details. to change a lens, follow the steps below. no tools are required for “compact” lenses shown.

    step 1

    turn off the projector, cool and unplug

    if necessary, a lens can be swapped out while the projector is running, but this can result in dust being drawn into the projector. avoid if possible.

    before removing or installing any lens, turn off the projector and allow the fans to cool the lamp before unplugging the projector. ensure that the lens cap is on.

    unplug the projector.

   

    step 2

    install the lens cap and press the lens release button see figure 4.9.

   

    step 3

    rotate the lens

    rotate the lens counter-clockwise until the tabs are free from the lens retainer ring.

    see figure 4.10a.

    the connector slide assembly allows the connector to move as the lens is rotated.

    step 4

    pull lens out

    lens connectors will disconnect when you pull the lens straight out from the projector. see figure 4.10b.

   

    step 5

    insert new lens.

    remove small rear cap! keep front cap on.

    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 ?inch.

    rotate the lens: rotate the lens clockwise until the tabs are tightly secured and the lens release button clicks.

    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 and section 6 and appendix e, throw distance. in a permanent installation, always use the appropriate throw distance formula to calculate the best position for the projector.
