CAUTION: For IS-1/DF-1 leads, never change the shock waveform polarity by physically switching the lead
anodes and cathodes in the pulse generator header—use the programmable Polarity feature. Device damage
or nonconversion of the arrhythmia post-operatively may result if the polarity is switched physically.
Connect each lead to the pulse generator by following these steps (for additional information about the torque
wrench, refer to "Bidirectional Torque Wrench" on page 64):
a. Check for the presence of any blood or other body fluids in the lead ports on the pulse generator header.
If fluid inadvertently enters the ports, clean them thoroughly with sterile water.
b. If applicable, remove and discard the tip protection before using the torque wrench.
c. Gently insert the torque wrench blade into the setscrew by passing it through the preslit, center
depression of the seal plug at a 90° angle (Figure 6 on page 56). This will open up the seal plug, relieving
any potential pressure build-up from the lead port by providing a pathway to release trapped fluid or air.
NOTE: Failure to properly insert the torque wrench in the preslit depression of the seal plug may result
in damage to the plug and its sealing properties.
CAUTION: Do not insert a lead into the pulse generator connector without taking the following
precautions to ensure proper lead insertion:
• Insert the torque wrench into the preslit depression of the seal plug before inserting the lead into the
port, to release any trapped fluid or air.
• Visually verify that the setscrew is sufficiently retracted to allow insertion. Use the torque wrench
to loosen the setscrew if necessary.
• Fully insert each lead into its lead port and then tighten the setscrew onto the terminal pin.
