Working with monitors, in common with any prolonged close work, can be 

visually demanding. Look away from the screen periodically and have your 

eyesight checked regularly.

Set the screen brightness and contrast to a comfortable level. You may have 

to adjust this as the lighting changes during the day. Many application 

programs let you select color combinations which can help you to view in 

comfort. See the User controls section on page 19 for more information.

Be sure to turn off the power before you perform any maintenance on the 

monitor. Clean your monitor as follows: 
• Gently wipe the device covers and the screen with a soft cloth.
• Remove finger marks and grease with a damp cloth and mild detergent; 

do not use solvents or abrasives

• Never use flammable cleaning material to clean your IBM monitor or any 

other electrical apparatus.

• Connect the power cord to the power port on the back of your monitor if 

the power cord supplied is not attached to the monitor.  Then insert the 

plug into a properly grounded electrical outlet.
