Maintenance guidelines

Cleaning your monitor

WARNING: Before cleaning the monitor, unplug the monitor power cable

from the electrical outlet.

CAUTION: Read and follow the

monitor.

Improper cleaning methods can result in physical damage to Dell monitors. Physical

defects may affect the screen and body of the monitor.

Follow the instructions in the list below when cleaning the monitor:

• To clean the Dell Monitor screen, lightly dampen a soft, clean cloth with water. If

possible, use a special screen-cleaning tissue or solution suitable for the Dell Monitor

screen.

•

CAUTION: Do not use detergents of any kind or other chemicals such as benzene,

thinner, ammonia, abrasive cleaners, alcohol, or compressed air.

• Do not directly spray the cleaning solution or even water on the surface of the

monitor. Directly spraying liquid onto the panel will roll down to the bottom of the panel

and corrode the electronics resulting in permanent damage.

• Instead, apply solution or water to soft cloth material.

NOTE: Using cleaner may cause changes in the appearance of the monitor, such

as color fading, milky film on the monitor, deformation, uneven dark shade, and screen

surface peeling.

NOTE: Monitor damages due to improper cleaning methods and the use of

benzene, thinner, ammonia, abrasive cleaners, alcohol, compressed air, detergent of

any kind will lead to a Customer Induced Damage (CID). CID is not covered under the

standard Dell warranty.
