Cleaning Information
How to clean lenses
1. Blow away any dust or dirt with compressed air.
Procedure for Stubborn Dirt
Use this procedure particularly when there is greasy dirt on the
adapter:
1. Clean the adapter by pushing and pulling a new, dry pipe-cleaner
into the opening. Rotate the pipe-cleaner slowly as you do this.
CAUTION Be careful when using pipe-cleaners, as the core and the bristles of the
pipe-cleaner are hard and can damage the adapter.
2. Clean the adapter by rubbing a new, dry cotton-swab over the
surface using a small circular movement.
3. Blow away any remaining lint with compressed air.
E.11 How to clean lenses
Some lenses have special coatings that are sensitive to solvents,
grease, liquid and mechanical abrasion. Take extra care when
cleaning lenses with these coatings.
Lens assemblies consisting of several lenses are not normally
sealed. Therefore, use as little alcohol as possible, as it can get
between the lenses and in doing so can change the properties of
projection.
Preferred Procedure
Use the following procedure on most occasions.
1. Clean the lens by rubbing a new, dry cotton-swab over the
surface using a small circular movement.
2. Blow away any remaining lint with compressed air.
