High Installation, Ceiling Mounting, and Rear Projection
Projector features enable projection from a shelf or other high surface. You can also mount the projector on the ceiling (ceiling mounting) with it turned upside down or place it behind the screen (rear projection) if you use a translucent screen. In [Image flip H/V] in the menu, choose a method of projection that corresponds to how the projector is installed

1 Press the MENU button on the remote control or projector, and then select [Install settings] > [Image flip H/V].
2 Select the orientation of how the projector is installed.

When setting the projector on a high surface for projection, be sure the surface is flat and stable. Failure to do so poses a risk of the projector falling and causing accidents or injury.

Ceiling mounting requires an optional ceiling attachment (part no.: RS-CL15) and ceiling-mount arm (part no.: RS-CL17). Depending on the installation environment, an extension pipe (part no.: RS-CL08 or RS-CL09) may also be required. Contact the Canon Customer Support Center for more detailed information.
 

• Make sure to use the optional ceiling attachment. • You should never install the ceiling attachment by yourself.
