21.3 Cleaning

Best cleaning practices.

When cleaning this product:

Do NOT wipe the display screen with a dry cloth, as this could scratch the screen coating.

Do NOT use abrasive, or acid or ammonia based products.

Do NOT use a jet wash.

21.4 Cleaning the display case

The display unit is a sealed unit and does not require regular cleaning. If it is necessary to clean the unit, follow this basic procedure:

1.Switch off the power to the display.

2.Wipe the display with a clean, soft cloth (a microfibre cloth is ideal).

3.If necessary, use isopropyl alcohol (IPA) or a mild detergent to remove grease marks.

Note: Do NOT use IPA or any other solvent or detergent on the screen itself.

Note: In certain conditions, condensation may appear inside the display screen. This will not harm the unit, and can be cleared by powering on the display for a short time.
