Maintenance

Cleaning lenses
1. Dampen a clean, lint-free cloth with vinegar or household ammo-
nia. You may use water, but it will leave spots which may be
removed by polishing the lens gently with a clean, dry cloth.
Warning : Never use glass and window cleaner or any abrasive
material to clean the lens. Glass and window cleaners will stain
the lens surface. Abrasive materials (such as steel wool) will
damage the surface of the lens.
2. Starting from the center, gently wipe the lens.
Cleaning the reflector
Remove dust with a blast of oil-free air or wipe with a clean, lint-free
cloth using alcohol or distilled water (alcohol is recommended).
Warning: Do not use glass and window cleaners on the reflector.
Chemicals in these cleaners will stain the reflector.
