2.4.2 Vertical and Horizontal Position
The projection lens and the screen type determine the vertical and horizontal position of your projector in
relation to the screen. Ideally, you should position the projector as perpendicular to the screen as possible to
project a rectangular image instead of keystoned (trapezoidal). The vertical position of the image (above or
below the optical axis) and the horizontal position of the image (left or right of optical axis) can both be offset
by adjusting the lens mount. The type of projection lens installed determines the amount of offset available.
Horizontal offset is also limited by the amount of vertical offset applied.
NOTE:
Offsets are subject to ±7%
centering tolerance.
Vertical offset can be expressed as:
Horizontal offset can be expressed as:
2.4.3 Ventilation
NOTICE:
Do not obstruct the air exchange to the projector.
The projector vents provide ventilation, both for intake and exhaust.
• Do not block or cover these openings.
• Do not install the projector near a radiator or heat register, or within an enclosure.
• Make sure there is a minimum clearance of 25 cm (10”) on all sides of the projector.
