12.2 Product cleaning
Best cleaning practices.
When cleaning products:
• If your product includes a display screen, do NOT
wipe the 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.
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 a mild detergent to remove
grease marks.
Note: Do NOT use solvents or detergents 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.
Cleaning the display screen
A coating is applied to the display screen. This
makes it water repellent, and prevents glare. To
avoid damaging this coating, follow this procedure:
1. Switch off the power to the display.
2. Rinse the screen with fresh water to remove all
dirt particles and salt deposits.
3. Allow the screen to dry naturally.
4. If any smears remain, very gently wipe the screen
with a clean microfibre cleaning cloth (available
from an opticians).
