Warning
• When installing the projector and adjusting the projection position, be sure to do so
as explained in this manual. The projector may fall and cause injury if installed and
adjusted improperly.
• To prevent the projector from falling, install it in a location and fasten it so as to ensure
sufficient strength to support the combined weight (about 28 kg) of the projector (about
21kg), the ceiling mount unit (about 7 kg) and so on for an extended period as well as
to withstand earthquakes. Insufficient 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 ceiling fixation bolts or screws.
* 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 ceiling
Ensure the load is mounted on a robust constructional material. If the strength of the
constructional material is insufficient, please reinforce it. Do not mount on ceiling
finishing material, furring strip etc.
• Mounting on a concrete ceiling
Use a commercial anchor bolt M6 (1/4 inch), anchor nuts and similar, which will bear
the load of the projector.

ways:
Installing the projector in a place such as wall and so on where ventilation  is poor,
