CLEANING  AND MAINTANENCE

CLEANING  AND MAINTANENCE

 

 

Cleaning 

Occasionally clean the display panel and cabinet with a soft cloth dampened (not soaked) with a 
mild (non-abrasive) glass cleaner. Keep turning a fresh side of the cloth toward the screen surface to 
avoid scratching it with accumulated grit. 

Do not use paper products as they may scratch the surface. To minimize the risk of abrasion, allow 
the screen to stand dry. 
Special care should be taken when cleaning a touch screen or polycarbonate shield that is installed 
over the screen. Abrasive and certain chemical cleaners can easily damage the surface. 

Never 

use alcoholic or ammoniac cleaners to clean the polycarbonate shield or a touch screen. 

 
Replacing a Line Cord 

To avoid shock and fire hazards, the monitor’s power cord should be replaced if the insulation       
becomes broken or if it develops a loose internal connection. 

 
Other Maintenance 

Qualified service personnel should perform all maintenance, except for the power cord replacement 
described above. 

 

Note:  

The solvent should be applied only to the cloth, and not directly on the monitor screen.

 

Note:  

For best results cleaning a monitor with the optional antireflective tempered glass display shield, a 
solution of denatured alcohol is recommended to thoroughly clean the display.
