Cleaning lenses

Caution! Change lenses if they become visibly damaged to
the extent that their effectiveness is impaired, for
example, by cracks or deep scratches.
1. Remove the lens assembly. (See Switching lens assemblies,
above, steps 1-3.).
2. Remove safety screen.
3. Dampen a clean, lint-free cloth with vinegar or household
ammonia. You may also use water, but it will leave spots which
you may remove by polishing the lens gently with a clean, dry
cloth.
WARNING! Never use glass and window cleaner or any
abrasive material to clean lenses. Glass and window
cleaners will stain the lens surface. Abrasive materials (such
as steel wool) will damage lenses.
4. Starting from the centre, gently wipe the lens.
5. Replace safety screen.
6. Replace the lens assembly.
