3.3 Disassembly and reassembly
3.3.1 LCD Display, D-LCC12A
WARNING Wear a static control wrist strap and soft cotton gloves (dust free) when
handling the LCD display parts. Hold them by their corners or edges. Do not
touch the connector pins.
In normal circumstances it is very difficult to keep the LCD Display component and the display
shield surfaces free of dust, when the LCD Display unit assembly is opened and they are
exposed to room air. If dust particles remain on the LCD Display component and the display
shield surfaces, they may impair the picture quality on the screen.
In case you need to detach the LCD Display component for repair, you may return it to be
repaired at GE Healthcare. If you can provide a dust free environment, follow the instructions
below.
