8. Verify impedances are acceptable by using the CP or Remote Control to measure impedances.
9. Evaluate Lead placement:
a. Evaluate whether stimulation is appropriate to reduce symptoms.
b. Adjust the Lead location or stimulation parameters if necessary.
Note: The stylet should remain in place throughout Lead insertion and adjustments.
WARNING: High charge density can cause permanent tissue damage. The Clinician Programmer will limit
stimulation parameters to safe values.
WARNING: Increasing the number of Lead penetrations increases the probability of hemorrhage. The necessity
for an acute Lead revision should be minimized using techniques of target localization, such as microelectrode
recordings and imaging, to correctly place the Leads on the first attempt.
10. Turn off the External Trial Stimulator.
WARNING: A sudden increase in stimulation may occur if External Trial Stimulator is ON while disconnecting the
OR Cables.
11. Disconnect the OR Cable and OR Cable Extension from the proximal end of the Lead.
