Maintenance Guidelines

Cleaning Your Monitor

CAUTION: Read and follow the Safety Instructions before cleaning the monitor.

WARNING: Before cleaning the monitor, unplug the monitor power cable from the electrical outlet.

For best practices, follow the instructions in the list below while unpacking, cleaning, or handling your monitor:

•To clean your touch screen, lightly dampen a soft, clean cloth with water. If possible, use a special screen-cleaning tissue or solution suitable for the anti- static coating. Do not use benzene, thinner, ammonia, abrasive cleaners, or compressed air.

•Use a lightly-dampened, warm cloth to clean the monitor. Avoid using detergent of any kind as some detergents leave a milky film on the monitor.

•If you notice white powder when you unpack your monitor, wipe it off with a cloth.

•Handle your monitor with care as a darker-colored monitor may get scratched and show white scuff marks more than a lighter-colored monitor.

•To help maintain the best image quality on your monitor, use a dynamically changing screen saver and turn off your monitor when not in use.
