Display Monitors Preventative Maintenance
5 - 2 0070-10-0634 Panorama® Service Manual
5.1 Display Monitors
The monitor panel and housing should be cleaned as required, but at least semi-annually.
The following internal cleaning procedures should only be performed by a trained, qualified
electronic technician.
NOTE: Never use an abrasive glass cleaner containing highly
concentrated ammonia and strong base chemicals since
they damage the surface treatment.
WARNING: Do not clean the monitor while it is on and/or plugged in.
5.1.1 CRT Display
Turn the AC power off and unplug the AC line cord and all other cables from the rear panel.
Clean the exterior of the monitor case with a lightly moistened cloth. Do not sterilize the
monitor with gas or other sterilization procedures.
Internal Cleaning - The monitor should be vacuumed yearly (at a minimum) to minimize the
potential of an electrical short.
5.1.2 LCD Display
Clean the cabinet and controls with a lightly moistened soft cloth.
5.1.3 Care and Cleaning of the Touch Screen
For the best performance, it is recommended that the touch screen on the Panorama
display(s) be kept clean. You can use any standard glass cleaner to clean the screen. Always
remember, however, to use a cloth or towel to apply the cleaner. Glass cleaner sprayed
directly on a display could possibly leak inside a non-sealed unit and cause damage.
Remove fingerprints and stains by using a liquid lens cleaner and a soft cloth.
To prevent scratches on the front panel of the display screen, observe the following
precautions when cleaning:
• DO NOT use abrasive cleaning materials to clean a touch screen.
• DO NOT wipe a dry screen.
• DO NOT use alcohol or chlorinated hydrocarbon solvents.
• Use a fine soft-hair brush to carefully brush away dust and dirt particles.
• Use a soft sponge moistened with cleaner solution to wipe the touch screen clean.
