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:

1Switch off the display.

2Tilt the panel.

3Unscrew the 4 sunken screws at the rear, fixing the glass panel and bezel.

4Remove 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-guardlight sensor on the LCD panel.
