Keep it Clean
The Optical Panel should not require regular interaction, but it must remain clean at all times. Make sure there is no dust, resin, fingerprints, or other debris that might obstruct the path of light through the panel. Clean the top surface only. Never touch the lens beneath.

How to Clean
To clean, use IPA 91% and a soft cloth to wipe away any resin. Finish with glass cleaner to remove all streaks and dust.
