CAUTION: Insert the lead terminal straight into the lead port. Do not bend the lead near the lead-header
interface. Improper insertion c an cause insulation or connector damage.
NOTE: If necessary, lubricate the lead connectors sparingly with sterile water to make insertion easier.
NOTE: For IS-1 leads, be certain that the terminal pin visibly extends beyond the connector block at
least 1 mm.
NOTE: For DF4-LLHH or DF4-LLHO leads, the terminal pin must be inserted beyond the setscrew block
to enable a proper connection. Visualization of the terminal pin insertion indicator beyond the setscrew
block may be used to confirm that the terminal pin is fully inserted into the lead port.
NOTE: For IS4-LLLL leads, the terminal pin must be inserted beyond the setscrew block to enable a
proper connection. Visualization of the terminal pin insertion indicator beyond the setscrew block may be
used to confirm that the terminal pin is fully inserted into the lead port.
e. Apply gentle downward pressure on the t orque wrench until the blade is fully engaged within the setscrew
cavity, taking care to avoid damage to the seal plug. Tighten the setscrew by slowly turning the torque
wrench clockwise, until it ratchets once. The torque wrench is preset to apply the proper amount of force
to the captive setscrew; additional rotation and force is unnecessary.
f. Remove the torque wrench.
g. Apply gentle traction to the lead to ensure a secure connection.
h. If the lead terminal is not secure, attempt to reseat the setscrew. Reinsert the torque wrench as described
above, and loosen the s etscrew by slowly turning the wrench counterclockwise, until the lead is loose.
Then repeat the sequence above.
i. If a lead port is not used, insert a plug into the unused port and tighten the setscrew.
CAUTION: The absence of a lead or plug in a lead port may affect device performance. If a lead is not
used, be sure to properly insert a plug in the unused port, and then tighten the setscrew onto the plug.
