CWT Compact S2 Installation & Maintenance Manual
This section is about cleaning of the outmost surface of the display modules. Cleaning the polycarbonate plastic display window in the cabinet door is described in section Cabinet door display window, cleaning.
| Caution: Do not apply excessive force to the display surface or the adjoining areas since this may cause the colour tone to vary. Don’t touch, push or rub the exposed polarizer covering the display surface of the LCD module with anything harder than an HB pencil lead. The polarizer is soft and easily scratched. Handle it carefully. Don’t put or attach anything on the display area to avoid marks. |
If the display surface is contaminated or dusty, gently wipe it with a soft dry cloth. To avoid damaging the surface do not scrub hard. If still not completely clear, moisten a cloth with isopropyl alcohol or ethyl alcohol.
Solvents other than those mentioned above may damage the polarizer. Especially, do not use water, ketones such as acetone, or aromatic solvents.
Immediately wipe off any drops of adhesives like saliva and water from the display surface. They might otherwise cause panel surface variations and color change.
