Preferred procedure
Use the following procedure on most
occasions.
1 Blow away any dust or dirt with compressed air.
Procedure for stubborn dirt
Use this procedure 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.
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.
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

2 Blow away any remaining lint with compressed air.
Never use any kind of solvent when cleaning a bare fiber adapter
as solvents can:
- damage the foam inside some adapters;
- deposit dissolved dirt in the groove, which can then dirty the
surface of an inserted fiber.
C A U T I O N
Be careful when using pipe cleaners, as the core and the bristles of
the pipe cleaner are hard and can damage the adapter.
