Selecting Contacts
You can manually assign anodes and cathodes in Custom Mode or incrementally steer a
stimulation field along the lead in the Steering Mode. Steering Mode is limited to a monopolar
configuration of either a single cathode or adjacent cathodes. You may assign the case and all the
contacts as anode or cathode individually in Custom Mode. The ETS is limited to Custom Mode
since the case cannot be assigned as an anode.
Note: Switching from Custom Mode to Steering Mode will clear the contact and case assignments.
Steering Mode
Steering Mode is an enhanced way of conducting a monopolar review where the contact(s) act
as the cathode(s) and the stimulator case acts as the anode. This mode allows you to steer a
monopolar cathode along the lead, eliminating the need to turn ON and OFF individual contacts.
Steering Mode incrementally shifts a percentage of the cathodic current to the adjacent contact(s)
using current steering technology to create smooth transitions between contacts.
The DB2201-Standard Lead has 8 contacts per lead, labeled 1 through 8 for one lead and 9-16 for
the second lead.
To Steer along the DB2201-Standard Lead:
1. Select Steering Mode.
2. Select a contact to assign it as a 100% cathode.
3. Use the
and
cathodic current will shift in 10% increments.
Note: The amplitude for the selected Area will drop to 0 mA when another contact is selected.
The DB-2202 Directional Lead has a total of 8 contacts per lead, labeled 1-8 for one lead and 9-16
for the second lead. Contacts 1 and 8 are the proximal and distal contacts while contacts 2-7 are
the small directional contacts for one lead. Contacts 9 and 16 are the proximal and distal contacts
while contacts 10-15 are the small directional contacts for the second lead.
To Steer along the DB2202-Directional lead:
1. Select Steering Mode.
2. Select a contact to assign it as a cathode
3. Use the

6. To choose another starting point or to Steer on another contact, click another contact.
Note: The total amplitude for the selected Area will drop to 0 mA when another contact
is selected.
