27. Cleaning the Display

27.1 Metal Surfaces


These can be wiped with an absorbent towel. Do not allow any liquid to get into the
electronic box.

Check the perforated metal of the electronic box periodically for accumulated dust.
Use a vacuum cleaner to remove the accumulation.

27.2 Cleaning Front AR Glass

Antireflective coatings can be difficult to clean to perfection. We recommend the
following:

Use a soft, lint-free towel or paper. Premium cheesecloth works well.

Use quality glass cleaner suitable for LCD screens. A premium grade of isopropyl
alcohol (IPA) can also be used, either by itself or as a supplement to the glass
cleaner. Use the IPA separately from the glass cleaner, i.e. don't mix them. Ideally
use different towels for each liquid.
Note: IPA is flammable. DO NOT USE IPA NEAR AN OPEN FLAME OR OTHER
IGNITION SOURCE.

DO NOT allow either the glass cleaning solution or IPA to enter the electronic box or
the gap between the backside of the Display Glass and the Display Chassis.

Apply the cleaning liquid, glass cleaner or IPA sparingly to the towel (as opposed to
the glass surface) and start at one side of the screen. Use a circular motion and work
your way across the screen. The glass cleaner should evaporate to a clean, streak-
free surface. Some suggestions include:

Avoid coming in contact with the exposed perimeter found on the Planar
LookThru. Contact with the edge seal may result in introducing a residue onto the
AR coating. This will complicate the cleaning process.

If the surface is not streak-free, increase the amount of cleaner applied to the
cloth and replace the towels more often.
