4. MAINTENANCE
Panel
Take care not to damage or scratch the panel. Clean
with a soft woolen or cotton towel. Use a watery
solution or a mild commercial glass cleaning product.
Cabinet
Do not use chemical cleaning products, benzene,
toluene, xylene or other solvents. Clean with a soft
cloth dampened with mild detergent and water.
Repeat with water only and wipe dry with a dry cloth.
Removing dust from the rear of
the glass panel
It may be possible that dust particles have entered
the display and are stuck to the rear of the glass.
We recommend to let this cleaning procedure be
done in a BARCO service center.
However, when really necessary, you can perform the
cleaning on site if you can work in conditions that
are as clean and dust-free as possible. This is to
avoid more dust entering the display when opening it.
To remove the glass panel:
1 Switch off the display.
2 Tilt the panel.
3 Unscrew the 4 sunken screws at the rear, fixing
the glass panel and bezel.
4 Remove the bezel with glass panel.
Cleaning instructions:
- Dust, fingerprints, grease etc. can be removed by
using a soft damp cloth (a
small amount of mild
detergent can be used on the cloth, NOT solvent).
- Do not apply liquid directly to the LCD surface as
excess liquid may cause damage to internal
electronics.
- Take care not to touch the I-guard light sensor on
the LCD panel.
