Caution:
Battery
depletion may occur
between visits and may
not be detected by the
various battery
indicators. Therefore,
LivaNova recommends
daily magnet activation
by the patient as the
primary test for battery
depletion for patients
with magnet activation
enabled.

End of Service (EOS):
This indicator is only applicable for Models
103, 104 and 105 Pulse Generators. When the Pulse Generator has
reached EOS, it is no longer supplying stimulation and immediate
replacement is recommended. The Programming Software will display
a warning message to the user indicating EOS status (see Figure 9 on
page 19). If the Pulse Generator is not replaced, it will eventually lose
the ability to communicate with the Programming Software.

System Diagnostics
The System Diagnostics (as shown in Figure 23 on page 40), which
LivaNova recommends you perform before other tests, is performed with
the Bipolar Lead and the Pulse Generator connected. A successful System
Diagnostics during surgery shows that both components are working
properly. Test failure may be due to defects of either of the components or
a faulty electrical connection between the Pulse Generator and the Bipolar
Lead connector pins. If a defective component is suspected, disconnect the
Bipolar Lead and perform the Generator Diagnostics (Pulse Generator
Test) using the resistor assembly supplied with the Pulse Generator (see
Figure 26 on page 43).
A successful Generator Diagnostics (Pulse Generator Test) confirms that
the Pulse Generator is functioning properly, independent of the Bipolar
Lead. For a failed Generator Diagnostics, see “Troubleshooting ” on
page 61.
If either component is defective or damaged, contact LivaNova and return
the item (following the disinfection procedure described in the physician’s
manual for the VNS Therapy Pulse Generators) with a completed
Returned Product Form.
