2. Adjust the focus at the edges of the projected image. (Manual focus)
Turn the edge focus ring clockwise or counterclockwise.
This completes adjusting the projected image's overall focus.
NOTE:
• The NP31ZL-4K supports the Lens Memory function, which allows you to store adjusted value for Lens Shift, Zoom, and Focus.
If you accidentally move the Edge focus ring (drawing shown below) after having stored adjusted values, the adjusted values
stored in the Lens Memory will not be correctly applied.
After having removed the lens from the projector and mounted it back, call up the adjusted values stored in the Lens Memory and
then follow Step 2 in the procedure above to adjust the focus at the edges of the projected image again.
