=== Cleaning the Lens ===


Note that Q-tips are abrasive and will wear away the coating on the lens. Always use a lens tissue.

# Remove the front cover using the three screws.
## Screws are captive - they won't fall out when they're loosened
# Wrap a Q-Tip with half a sheet of lens tissue
# Spray lens cleaner on half of the Q tip (block with your hand to keep the other half dry). Do not use Windex or anything other than lens cleaner.
# Clean the top and the bottom of the lens. Do not press hard/scrub; treat the lens like you would an eyeball.
# Dry the top and bottom of the lens using the dry side of the Q-tip.
# Clean the mirror (inside the head assembly). Do not attempt to loosen or remove the mirror.
# Dry the mirror using the dry side of the Q-tip.
# Replace the cover. Make sure the arms of the lens assembly are horizontal and resting on the two support pins of the head assembly.
