| Mounting the | installation, one method may be more suitable than another. | |
| 
 | 
 | 
 | 
| Floor Mounting (Upright) ➤ | In typical front and rear screen installations, the projector can be mounted to a secure and | |
| 
 | level surface such as a table or cart. Carts are useful when moving a projector during a | |
| 
 | presentation or from site to site. If possible, lock the wheels when it’s in position to prevent | |
| 
 | it from being moved during a presentation. | |
| Ceiling Mounting ➤ | For fixed installations, and for those that want the projector out of sight or have a limited | |
| (Inverted) | space for projector and audience, you can invert the  | |
| 
 | ceiling using a  | |
| 
 | Note | Use only the  | 
| 
 | projector. Install the mount kit according to the instructions | |
| 
 | 
 | provided with it. | 
| 
 | The projector can also be inverted and placed in an enclosure above and behind the | |
| 
 | viewing area. Install four feet on the inside bottom surface of the enclosure on which the | |
| 
 | projector can rest. A variety of materials can be used for this purpose (for example, rubber | |
| 
 | crutch tips or turntable feet). | |
| Adjusting the Projection ➤ | If the  | |
| Angle | you can tilt the projector at a slight angle by adjusting the ceiling mount. | |
| 
 | If you do this, you may need to shift the image or apply keystone correction using the OSD | |
| 
 | controls, to compensate. For detailed instructions, refer to Using the  | |
