Clean the display window as specified. Use of abrasive
cleansers or solvents may damage the window. Do not scrub

!
1. Disconnect power from the display at the power source.
2. Using a clean sponge or a soft cloth, clean the window with a mild soap
or detergent.
2. Dry the window with a chamois or moist cellulose sponge to prevent
water spots.
Removing Paint and Grease
Fresh paint splashes and grease can easily be removed before drying by
rubbing lightly with isopropyl alcohol. Afterward, a warm final wash should
be made using a mild soap or detergent solution and ending with a thorough
rinsing with clean water.
Removing Hairline Scratches
Scratches and minor abrasions can be removed or minimized by using a mild
automobile polish. We recommend that you first test the product on a small
area.
