The case is constructed of high-quality materials and does not 

require user maintenance, except cleaning.

Clean the unit’s outer casing (except for the screen) using a cloth 

dampened with a mild detergent solution and then wipe dry. Avoid 

chemical cleaners and solvents that may damage plastic components.

The lens on the screen is coated with a special anti-reflective coating 

that is sensitive to skin oils, waxes, and abrasive cleaners. Cleaners 

containing ammonia, alcohol, abrasives, or anti-grease detergents 

will harm the anti-reflective coating. It is important to clean the lens 

using an eyeglass lens cleaner (that is specified as safe for anti-

reflective coatings) and a clean, lint-free cloth.
