LEAD CONNECTIONS

Lead connections are illustrated below.

CAUTION:

Prior to implantation, con

fi

rm the lead-to-pulse generator compatibility. Using incompatible leads

and pulse generators can damage the connector and/or result in potential adverse consequences, such as
undersensing of cardiac activity or failure to deliver necessary therapy.

CAUTION:

If the Lead Con

guration is programmed to Bipolar when a unipolar lead is implanted, pacing

will not occur.
