2. Program the settings into the IPG by selecting the Download Settings to IPG button.
The values of the parameters programmed into the IPG, as displayed in the Implant
Settings menu, will be delivered to the patient with every triggered therapy.
3. Select desired Therapy Mode (Figure 5.1). The Normal therapy mode is the default
where a single stimulation is delivered when the button is pressed. You can choose to
deliver a string of stimulations instead of a single stimulation by selecting the Continuous
mode and then pressing and holding the push button to start the stimulation and releasing
the push button to end the stimulation.
4. In the case where you may prefer to use a magnet to provide the trigger to initiate
stimulation, select the Start button in the On-Demand Magnet Trigger section. This
initiates on-demand VNS using a magnet swipe instead of VNS triggered through the VNS
Pairing Therapy menu. You can choose to deliver a string of stimulations instead of a
single stimulation by selecting the Continuous mode along with On-Demand Magnet
Trigger and then using the magnet to start and stop the stimulation.

SAPS prevents the On-Demand Magnet Trigger function from operating simultaneously with
the VNS Pairing Therapy function. Tasks performed during On-Demand Magnet Trigger
therapy are not captured in the patient log file.
The status of the Therapist Trigger Mode is reflected in the Program Implant menu (see
Section 4.4.2: Therapist Trigger Mode) and vice versa.
The on-demand stimulation therapy can now begin via the VNS Pairing Therapy menu.
