screen. The largest the image can be is 300" (7.6 m) when the projector is about 484 inches (12.3 m) from the wall
or screen. Use the chart below as a rough guide.

NOTE:
• The distances are indicated by intermediate values between tele and wide. Use as a rule of thumb.
• The Zoom lever adjusts the image size up to +/-10%
• For more details on throw distance, see next page.
• Changing the image size starts the AUTO FOCUS to adjust the focus; changing the throw angle starts the Auto Keystone to
correct the vertical keystone distortion.
