CLEANING THE SCREEN AND MIRRORS
Periodic cleaning of the screens, mirrors, and lens is necessary to maintain a high quality image on the PMCD750 display. Environmental
conditions will dictate the frequency of this type of maintenance.
When particles of dirt appear in the image, use a white test image to clarify the location and sharpness of the contaminates. Small specs of dirt
or dust that are in very sharp focus will indicate the screen needs cleaning; those that are softer in focus indicate that the large mirror needs
cleaning.
For mirrors and screens, any glass cleaner (foam or spray) that is designed for use on glass and acrylic surfaces is acceptable.
White cotton cloth is preferrable to colored cloth due to the coloring dyes making the cloth less absorbent. Cheesecloth is another effective
choice because it is light and absorbant. Paper towels leave behind lint and should be avoided.
REMOVING DRY DUST
When cleaning does not involve fingerprints or other oily dirt, use a dry cheesecloth or any cleaning product designed specifically for picking
up dust.
CLEANING THE LENSES
The lenses are cleaned in the same manner as the mirrors.
WARNING: Do not spray liquid of any kind on the screen. If sprayed directly on the screen, liquid will drip down and wick up between the
layers of the screen. This discoloration is impossible to remove and will ruin the screen. First spray the cleaner on a cloth, and then clean
the screen.
