channel.
7. Reinsert the flat cables if you want to measure the bottom side of the PCA under
working condition. See Figures 6-2, 6-3, and 6-4 at the end of this chapter.

place the isolation foils around the channels.

Proceed as follows:
1. Unlock both flat cables by shifting the connector latch at the left and right edge using
a small screwdriver. The latch is an integral part of the connector body.
2. Remove the flat cables from connector X9303 (to LCD), J9414 (to keyboard), J9415
(to LCD backlight).
3. Remove 6 self-tapping screws 10 mm long (total length) that fix the Main PCA
module to the top case assembly.
4. Separate the Main PCA module from the top case.
Now you have access to LCD-module, keypad foil and keypad. They can be
separated from the top case without the removal of screws or clamps.
5. To prevent contamination, do not touch contact areas with your hands or wear cotton
gloves.
When installing the LCD-module into the top case, take care that no dust or
dirt is present between module and the window/decal.
Before reinstalling the Main PCA module on to the top case, place the grey
plastic strip around the BNC inputs.
