Cleaning Instructions
Perform all cleaning operations (lenses, filter/protection glass, sensor in a
dust-free clean-room. The optical components are very fragile so it is impor-
tant to avoid touching them with your fingers or any hard material.
1. Unplug the camera from any power supply before cleaning.
2. Apply a small amount of optics cleaner (60% ethyl alcohol, 40% ether)
to clean, new lens cleaning tissue.
Acceptable material includes medical-grade sterile optical cotton, or
lens tissue that is chemically pure and free from silicones and other
additives.
– Do not use cosmetic cotton.
– Do not use consumer eyeglass cleaning cloths pre-treated with sili-
con.
