Positioning your projector

Choosing a location
Your room layout or personal preference will dictate which installation location you select. Take into consideration
the size and position of your screen, the location of a suitable power outlet, as well as the location and distance
between the projector and the rest of your equipment.
Your projector is designed to be installed in one of the possible installation locations:
1.
Front Table
Select this location with the projector placed near the
floor in front of the screen. This is the most common way
to position the projector for quick setup and portability.
2.
Rear Table
Select this location with the projector placed near the
floor behind the screen.
Note that a special rear projection screen is required.
Set Rear Table in the SYSTEM SETUP: Basic >
Projector Position menu after you turn the projector on.
For ceiling mounting, you need the ceiling mount kit designed for this projector. Ask a specialist for installation.For
details, consult your dealer.
The warranty on this projector does not cover any damage caused by use of any non-recommended ceiling mount
kit or installation of the ceiling mount kit in an improper location.
When the projector is mounted on the ceiling, images may appear darker than those projected in the case of
tabletop mounting. This isn't a product malfunction.
Be sure to use this projector at an altitude of less than 1500 meters.
Installation must be done by a qualified professional.
When the projector is installed on the ceiling using the ceiling mount kit, it is recommended to hold the mount kit and the
projector using metal bars or wires in addition to the mount kit fixing screws to prevent the projector from falling due to
an earthquake or other cause. For that purpose, use metal bars, wires, or screws that bear a load of at least 70 kgf. When
using metal wires, secure one end to a screw hole marked with an arrow on the rear terminal panel and the other end to
the mount kit. (Do not use screw holes without arrow marks.) In this case, make sure that the screws are inserted in the
projector at least 5 mm. The length of the screws should be 20 mm or shorter. Also make sure that no electrical current is
flowing in the mount kit due to current leakage or other cause.
3.
Rear Ceiling
Select this location with the projector suspended upside-
down from the ceiling behind the screen.
Note that a special rear projection screen and qualified
projector ceiling mount kit are required for this
installation location.
Set Rear Ceiling in the SYSTEM SETUP: Basic >
Projector Position menu after you turn the projector on.
4.
Front Ceiling
Select this location with the projector suspended upside-
down from the ceiling in front of the screen.
Purchase a qualified projector ceiling mount kit from
your dealer to mount your projector on the ceiling.
Set Front Ceiling in the SYSTEM SETUP: Basic >
Projector Position menu after you turn the projector on.
