Appendix V
The Cleaning of the Clear Down Cover
To obtain constant clear videos, the down cover should be cleaned periodically.
Be cautious when cleaning. Hold the down cover ring only to avoid direct touch to
the acrylic down cover.
The acid sweat mark of a fingerprint will corrode the coating of down cover and
scratches on the down cover will cause vague images.
Use s soft dry cloth or a substitute to clean the inner and outer surfaces.
For hard contamination, use neutral detergent. Any cleanser for high grade
furniture is also applicable.
