• When lifting or moving the monitor, do not turn the monitor upside down while holding the stand base or stand riser. This may result in accidental damage to the monitor or cause personal injury. Maintenance guidelines Cleaning your monitor WARNING: Before cleaning the monitor, unplug the monitor power cable from the electrical outlet. CAUTION: Read and follow the Safety Instructions before cleaning the monitor. For best practices, follow these instructions in the list below while unpacking, cleaning, or handling your monitor: • To clean your anti-static screen, lightly dampen a soft, clean cloth with water. If possible, use a special screen-cleaning tissue or solution suitable for the antistatic coating. Do not use benzene, thinner, ammonia, abrasive cleaners, or compressed air. • Use a lightly-dampened, soft 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.
