Q: |
How and when should I clean the lens? |
A: |
Clean the projector's lens and interactive module's receiver window periodically, or whenever you notice dust or smudges on either surface.
Caution: Do not use glass cleaner to clean the lens or receiver window, or you may damage them. Do not use canned air, or the gases may leave a residue. Avoid touching the lens or receiver window with your bare hands to prevent fingerprints on or damage to either surface. |
