(3) Dress the cable as shown in the figure. The cable needs to

panel of the transceiver.
(4) Cut off the projection of the top packing using a pair of nip-
pers or similar tool.
If the cable is dressed to be routed through the indentations
on the right side in step 4, the right side of the projection
needs to be cut off.

cut off.
Following is a figure presenting an example for when the
right side of the projection is cut off.
