Cleaning the Glass Lens
Step 1: Remove the beam focus knob from the barrel.
Step 2: Remove the lens tube from the barrel.

Isopropyl alcohol, distilled water, or a 50%-50% mixture of each can be
used to clean the glass surface.
Step 4: Slide the lens tube back into the barrel with the colour frame retainer clip
on the top.

WARNING:
Do not use ammonia-based or other harsh commercial
cleaners. Clean lens only as directed.
Commercially available glass cleaning agents should be
avoided as they may contain ammonia, other harsh chemical
detergents, or abrasive agents. These cleaners may damage
the glass surface and the Anti-Reflective coatings. Do not
immerse or soak the glass in any cleaning solution.
