Cleaning the deflection mirror
Damage to the optical effective surface of the deflection mirror!
Incorrect cleaning or aggressive cleaning agents can damage the deflection mirror, thus
impairing the reading quality of the ICR890 System.
¾
If possible, do not clean the deflection mirror.
¾
Only clean the reflector surface if absolutely necessary (e. g. heavy soiling). Never touch
the entire reflector surface.
¾
Do not use canned compressed air.
¾
To avoid irreversible scratches,
never
clean the mirror with a cloth.
Removing dust and loose dirt particles
¾
Carefully blow off dust and loose dirt particles using
cleaned, oil-free air
.
Do not use canned compressed air, since it can contain alkaline substances which
corrode the surface of the mirror.
Removing solid particles
¾
Carefully remove more solid particles with a degreased camel hair brush (previously
treated with acetone). Ensure that acetone does not come into direct contact with the
reflector surface.
Cleaning the deflection mirror intensively
1. Fill a clean plastic spray bottle with distilled water.
2. Evenly spray distilled water onto the reflector surface.
Keep the mirror tilted, allowing the distilled water to drip dry.
3. Allow the mirror to dry.
Do not wipe the mirror dry!
Removing grease deposits
1. Spray affected areas with household glass cleaner.
2. Use a paper towel (recommended: “Kleenex“) to wipe the affected area. Only apply
slight pressure to the mirror. Do not scour.
