Portrait projection (vertical orientation)
If you install the projector vertically you can project screens from your
computer and other sources in portrait orientation.
• Be sure to install the device with the side where the Connection termi-
nals and Controls/Indicator Panel are located facing the top.
• Direction of On-Screen display (menu, source display and messages)
can be changed by the menu.
Precautions during installation
• Do not simply set the projector vertically on the floor or on a table. The projector may fall over, resulting in injury,
damage or malfunction. Also the intake vent may become blocked causing the unit’s internal temperature to rise
resulting in malfunction and risk of fire.
• For portrait installation the intake vents must be installed at the top and bottom. To ensure air flow to the bottom
intake vent, a rack to support the unit is necessary. Please hire an installation service provider (for a fee) to
make a custom portrait projection stand.
• When installed in portrait orientation the projector can be tilted forward or backward
within a range of ± 10°. Tilting the projector forward or backward outside of this range, or tilting it to the left or to
the right could cause it to malfunction.
• To ensure air flow, maintain 60 cm/23.6" of space between the intake
vent and the installation surface.
(NOTE) In the figure to the right there is plenty of space behind, above,
and on either side of the projector unit.
