4. Fully insert the hex wrench (packaged with the neurostimulator) into the self-sealing
grommet of the connector block and tighten each setscrew.

Cautions:
To avoid undertightening, do not use a torque wrench. Undertightening the
■
neurostimulator setscrews may result in insufficient electrical contact within the
connector block, resulting in intermittent or loss of stimulation.
Be sure the hex wrench is fully inserted into the self-sealing grommet. If the hex
■
wrench is not fully inserted, the setscrew may be damaged, resulting in
intermittent or loss of stimulation.
Before tightening setscrews, ensure that the extension connector pins are
■
inserted into the connector block to prevent damaging the connector block.
When using the hex wrench, do not overtighten the setscrews. Overtightening
■
may damage the setscrews and prevent setscrew removal.
Verify that each leaf of the self-sealing grommet is closed after the hex wrench
■
is withdrawn. If fluid leaks through a grommet seal that is not fully closed, the
patient may experience shocking, burning, or irritation at the neurostimulator
implant location, or intermittent stimulation or loss of stimulation may occur.
Note: The hex wrench must be oriented to the same angle as the setscrew (Figure 2).
