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 Unplug the cable plugged in on the bezel.
5 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.
