WARNING: High charge density can cause permanent tissue damage. The Clinician
Programmer will provide either a warning when exceeding 30 µC/cm
the stimulation parameters to safe values.
WARNING: Increasing the number of DBS Lead penetrations increases the probability
of hemorrhage. The necessity for an acute DBS Lead revision should be
minimized using techniques of target localization, such as microelectrode
recordings and imaging, to correctly place the DBS 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 DBS Lead.
12. Verify that the DBS Lead has not moved from the desired location.

The following steps are for procedural reference only. Refer to the appropriate Programming
Manual for detailed stimulation procedures and guidelines.
CAUTION: Do not immerse the OR Cable connector or plug in water or other liquids. The
OR Cable is intended for one-time use only; do not resterilize.
1. Ensure that the locking lever on the OR Cable connector is in the open (
2. Slide the proximal end of the DBS Lead, with stylet, into the open port labeled "C" on the OR
Cable connector. If two DBS leads are being used, connect the left DBS lead to Port C and the
right DBS lead to Port D.
Note: The descriptors "proximal" and "distal" use the Stimulator as reference.
