Problem Possible cause Solution
Display does not come on Low batteries Load batteries
Weak stimulation with loaded
batteries
Electrodes dried out, lost their
adhesive power and have no
adequate connection to th skin.
Replace electrode
Electrode placement
Make the electrodes at least 2”
apart
Stimulation stops with loaded
batteries
Poor electrode contact
Reapply electrodes, secure firmly.
Electrodes must be a minimum
of 2 inches apart.
Damaged or worn electrodes or
module leadwires
Replace.
Stimulation weakens within
minutes of starting treatment
with loaded batteries
This is a normal body adaptive
process
Increase the amplitude
(intensity) if required.
Stimulation is uncomfortable
Amplitude (intensity) is too high Decrease amplitude (intensity).
Electrodes are too close together
Reposition the electrodes.
Electrodes must be a minimum
of 2 inches apart.
Damaged or worn electrodes or
leadwires of modules
Replace.
Ensure proper program is being
used
A. Refer to section 6.1 and 7 for a
description of the Programs
B. Contact clinician if discomfort
persists.
Stimulation is ineective
Improper electrode placement
Reposition electrodes. Electrodes
must be a minimum of 2 inches
apart.
Unknown Contact clinician.
Stimulation only felt on one
electrode
Improper electrode placement
A. Reposition electrodes.
Electrodes must be a
minimum of 2 inches apart.
B. Replace electrodes.
