Step 6.Remove Some Cables
1. Place the analyzer bottom-side up on a flat surface.
2. Remove and discard the following gray flexible cables:
— W130 A20 IF multiplexer (P203) to A12 SPAM (J5)
— W129 A20 IF multiplexer (P603) to A12 SPAM (J2)
Be careful not to damage the center pins of the semirigid cables. Some
flexing of the cables may be necessary but do not over-bend them.
Leave the gray flexible cables, the wire harnesses, and the ribbon cables
connected where possible. Any that are removed should be labeled for
reconnection later .
When removing a cable, also remove the plastic cable clamp, if present. It
is normal for some of the cable clamp’s adhesive to remain.
