  • unit: mm (inch)
  • L: Distance to screen
    H: Height from the edge of screen to center of lens
  • *1 When the lens protrudes to the maximum.

    A: 79.5 mm (3-1/8 in) with the ET-ELW20
    60 mm (2-3/8 in) with the supplied lens
    84 mm (3-5/16 in) with the ET-ELT20
    80 mm (3-5/32 in) with the ET-ELT21
    50 mm (1-31/32 in) with the ET-ELW21

  • *2 Adjustable in 30 mm (1-3/16 in) steps.
NOTE:
Illustrations show the projector installed using optional ceiling mount bracket ET-PKE200H and bracket assembly ET-PKE200B.
This illustration is not drawn to scale.
Caution:
• All construction work should be done by a qualified technician.
• When mounting to the ceiling, use the special mounting bracket. To prevent the projector from swaying or dropping, attach the wire between the mounting bracket and the ceiling.

• The value for L (distance to screen) varies slightly within ±5% depending on the zoom lens characteristics.
• The zoom lens characteristics may cause slight image distortion.
• When vertical keystone correction is used, the image is corrected in the direction that reduces its projected size.
• The brightness varies depending on the zoom setting.
• When the fixed-focus lens ET-ELW21 is mounted, the optical lens shift function cannot be used.
