8.2 Cleaning the Optics
The target window and optics should be cleaned once a week in normal
environments; and more often in dirty or dusty environments.
Target Window
1) Remove dust and lint from target window by wiping it with a clean, lint
free cloth, slightly moistened with water.
Optics
1) Unscrew the two thumb screws [1] and remove the nose piece [2].
Remove dust from aperture with camel hair brush or a camera lens
cleaner [3].
2. Blow short bursts of air into the optics opening using a camera lens
cleaner (with the brush removed) until all dust is removed. This can be
done with the nose piece removed or attached.
☛
WARNING! Do not use an air can that uses freon as a propellant. Doing so could cause damage to
the optics assembly.
