2 Remove the ten T10 screws, see Figure 71, ➊ – ➓, from the Therapy PCA.
3 Move all the wires aside.
4 Carefully but firmly grasp the Therapy PCA at positions K1 and T1 (see Figure 72) and lift the
Therapy PCA straight up.
NOTE: The Therapy PCA is shaped as a trapezoid and must be lifted straight up. Do not attempt to slide the
Therapy PCA from the Rear Chassis sideways, because it may get wedged and damaged.
There are two plastic shields under the Therapy PCA. Make sure you reuse both of them in the
replacement procedure.
