“Impedance measurement was rejected by the neurostimulator”
“Test request was rejected by the neurostimulator”
Issue
The neurostimulator cannot perform an impedance measurement or a test stimulation (therapy
testing).
Possible Cause

cannot be performed during responsive therapy.

stimulation cannot be performed while an episode is being detected.
Actions to be Taken

measurement; or
2. Wait until the neurostimulator is no longer detecting an episode.
