3. It is recommended to verify that the VNS settings chosen are tolerable for the patient. To
verify these settings, select the Test button to deliver a single train of stimulation per the
parameters displayed in the Implant Settings menu. Selecting the Test button programs
those displayed parameters into the IPG. The Download Settings to IPG function does
not need to be performed. The user can modify the parameters at any time by selecting
new parameters and programming them into the IPG using the Test function.
This sequence can be repeated until the patient’s IPG is programmed to appropriate
parameters.
In the scenario where a Test is not performed, the Download Settings to IPG button must be
selected to program the IPG with the therapy parameters displayed in the Implant Settings
menu.
CAUTION: If the Test function is not performed, new parameters are not input into the
IPG until the Download Settings to IPG function is used. Verify that the intended
parameters are programmed into the IPG. The suggested method of doing so is by
interrogating the IPG and comparing the displayed parameters to those intended to be
programmed.
