Care and Cleaning
Adherence to regular and proper cleaning procedures will
preserve the appearance of your device. Scratched or damaged
surfaces caused by misuse, mishandling, improper storage, or
improper cleaning are not covered under the limited warranty.
MINIMIZE HAIRLINE SCRATCHES
Always store the device face-up in the protective plastic shipping
bag until ready for installation and during transportation to the
installation site. Do not place the device face (lens surface) down
on any surface as this may scratch or mar the lens.
Scratches and minor abrasions can be minimized by using a mild
automobile polish. Three such products that tend to polish and
fill scratches are:
1. Johnson Paste Wax (Johnson and Johnson Co.)
2. Novus Plastic Polish #1 and #2 (Novus, Inc.)
3. Mirror Glaze plastic polish (MG M10)
(Mirror Bright Polish Co.)
We suggest a test be made on a very small section of the
polycarbonate lens with the polish selected and that the
manufacturer's instructions be followed.
A LIST OF "DON'TS"
Don't store the device without the protective plastic
shipment bag.
Don't store or place the device face down on any surface, as
this may scratch the lens.
Don't use abrasive or highly alkaline cleaners.
Don't use paper towels, paper products, rayon, or polyester
cloths to clean or dry the lens.
Don't scrape the lens with squeegees, razor blades or other
sharp instruments.
Don't use benzene, gasoline, acetone, methyl ethyl ketone
(MEK), muriatic acid, or carbon tetrachloride on the lens.
Don't clean lenses in hot sun or on very hot days.
