Step 13. Attach the RJ45 cable to the head brace being used and the RJ45 jack that is

closest to the front of the unit at the top of the MCU™ (Figure 6-71).

Step 8. Unlock the rotation pin, which is located at the top middle of the halo. If

you’re testing the patient’s left side, rotate the halo to 45 degrees right rotation, and

then lock the rotation pin. Rotate the halo to 45 degrees left rotation when testing the

patient’s right side (Figure 6-72). Note that the figures show a set-up for testing the

patient’s right side.

Step 9. Attach the head brace to the halo on the side being tested (Figure 6-73).

Step 10. Set the halo to 0 degrees with respect to the horizontal. Make sure the flexion/

extension angle is set to 0 degrees as well (Figure 6-74).

Step 11. Position the head brace against the patient’s head.

Step 12. Make fine adjustments to the seat to line up C5/C6 of the patient’s spine with

the pivot point of the halo (Figure 6-75).
