W WARNING
Far-field sensing or insufficient defibrillation
When shock coils and pace/sense electrodes are not spaced sufficiently apart or
positioned inappropriately, this can lead to far-field sensing or insufficient defibrilla-
tion:
• The distance between two shock coils must be greater than 6 cm.
• Pace and sense electrodes must not contact each other.
W CAUTION
Damage to the header while handling the blind plug
For every connection there is a blind plug in the header; the provided set screws must
be carefully loosened or tightened.
• Loosen set screws with the supplied screwdriver. Use BIOTRONIK screwdrivers
with torque control only!
• Do not forcibly pull out the blind plug!
• If lead repositioning is necessary, re-order sterile screwdrivers from BIOTRONIK.
W WARNING
Malfunctioning of the therapy functions or triggering of tachycardia by older,
unused leads
If, upon replacing the device, predecessor leads are no longer used but left where
they are, then their connections have to be insulated so that there is no additional
uncontrolled current path to the heart.
Connecting the ICD lead connector to the device
Leads are connected to the device according to the diagram on the header. Proceed as
follows:
1 Disconnect stylets and insertion aids from the lead connector.
2 • Connect ventricle shock coil to RV.
• Connect vena-cava shock coil or subcutaneous shock coil to SVC.
3 • Connect the bipolar IS-1-lead connector atrium to A S or P/S A.
• Connect the bipolar IS-1 lead connector ventricle to P/S V.
• Connect the unipolar or the bipolar IS-1 lead connector of the CS lead 
to P/S CS.
4 Push the lead connector into the header without bending the conductor until the
connector tip becomes visible behind the set screw block.

Setting the lead polarity manually
Due to the risk of an entrance/exit block, bipolar lead polarity (sensing/pacing) should
only be set if bipolar leads are implanted.
Implanting the ICD
Implantation site
In general the ICD is implanted subpectorally on the left depending on the lead
configuration as well as the anatomy of the patient.
ICD status prior to implantation
The ICD is shipped in a deactivated mode and can be connected and implanted in this
state.
W CAUTION
Shipment mode active!
During shipment, the device has been set to shipment mode.
The shipment mode reduces the battery's energy consumption, which may increase
longevity. The shipment mode controls the charge time of automatic capacitor refor-
mations.
The shipment mode must be deactivated before the conclusion of the implantation
procedure.
The shipment mode will be automatically deactivated as soon as electrophysiolo-
gical tests (e.g. impedance measurement) have been performed.

• Bipolar IS-1 connectors: tighten both set screws!
• When you withdraw the screwdriver, the silicone plug automatically seals
the lead connection safely.
