unit and so on for an extended period as well as to withstand earthquakes. Insuffi-
cient strength or fastening may result in the projector falling and causing injury.
Be sure to observe the following precautions:
- Use M6 (1/4 inch) for the wall fixation bolts and screws for the wall adapter.
- Use an outlet for the power source of the projector. Do not directly connect to the
lamp line because this is dangerous.Also, use an accessible outlet so that you can
connect and disconnect the power plug.
- Mounting on a wooden wall
Ensure the load is mounted on a pillar or robust constructional material. If the
strength of the constructional material and so on is insufficient, please reinforce it.
Do not mount on wall finishing material, furring strip and so on.
- Mounting on a concrete wall
Use a commercial anchor bolt M6 (1/4 inch), anchor nuts and similar, which will bear
the load of the projector.

Before installing
1. Consider the place where the screen is to be installed and determine the position in
which the wall mount unit is to be mounted. (See page ENG-7)
- It is not possible to install in such a way that the image is projected at an angle. Position
in such a way that the image is projected directly to the front.
2. Check that the position of installation meets the conditions in “Be sure to
read before installing” on page ENG-2 of these instructions.
- Because the elevation angle of the projector’s optical axis is large, small shifts in the
projection distance will change the size and position of the projected image significantly.
Also, if the direction in which the projector is facing is off, the distortion of the image in-
creases.
Installing the Projector

ENG-10
3. Attach the projector to the mount plate.

installed in the proper up/
down direction. Mount it
in the direction shown on
the diagram.
- The horizontal position
adjustment range is ±50
mm.
CAUTION
- Mounting should be per-
formed by two people.
WARNING
