Introduction
4. Cleaning of the reading window
•
Install the product so that the front area of the reading window is free of dust and oil
droplets.
If dust or oil droplets are found, clean the surface using the following method.
•
Blow large particles off using a blower brush (for camera lenses).
Do not blow using your own breath.
•
Gently wipe off small particles using a soft cloth (lens wiper) moistened with a small
amount of alcohol. Avoid vigorous wiping. Scratches on the reading window may
result in reading errors.
