APPENDIX B: Troubleshooting
Calibration
I cannot start the calibration procedure (the
lights are not running waterfall motion).
You should be sitting down with your leg at a 90°
angle (or perpendicular to the floor) with your
foot flat on the floor. Make sure the electrode
is snapped onto the device, the liner has been
removed, and the device is properly placed on
your leg (on the upper calf, 1-2” below your knee).
Electrode should be making complete contact with
the skin. Click and hold the button down for at
least 5 seconds until you see the white waterfall
pattern.
I can start calibration and see the waterfall lights
briefly, but then they turn off.
Check your positioning (seated with leg at 90°
angle) and device (upper calf, 1-2” below the knee).
Electrode should be making complete contact
with the skin. Try smoothing the electrode over
your skin (while it is snapped to the device), before
securing the sports band.
I am trying to calibrate but I don’t feel anything.
Confirm electrode liner has been removed and
that the lights have been running back and forth
for at least 30 seconds. The purpose of the
calibration process is to measure your sensation
threshold, meaning that when you feel even the
slightest sensation, you should click the button. Do
not wait until the sensation feels very strong to
click the button. It may take 20-30 seconds to feel
the sensation the first time and the sensation may
feel very light. You will feel subsequent stimulation
slightly faster. If you go through the calibration
process and never feel stimulation (or press the
button), the therapeutic intensity will be set at the
maximum possible intensity.
Important tips
It is a good idea to wait about 5 minutes after
putting the electrode on for the skin-gel interface
to stabilize, before you start calibrating.
If your leg is cold (for example, if you come in
from the outside during winter), you should wait
30-60 minutes so that your leg warms up to room
temperature before calibrating. The reason is that
cold will artificially elevate the sensation threshold
(the same reason cold makes you feel numb).
Do not calibrate right after a therapy session (of
>30 minutes) because the sensation threshold will
be artificially elevated. You should wait at least
1 hour and preferably 2 hours after a therapy
session.
Therapy
Make sure you initiate therapy only after the device
and electrode are properly placed on the calf.
I am pressing the button and getting a short
(2-second) blink of an orange light.
Recharge battery.
I start therapy and a white light blinks once (or up
to 4x if the button is held longer) and stops.
Your device has not been calibrated. You need to
calibrate device at least once before therapy.
I am not getting pain relief.
Make sure you feel a
strong but comfortable
sensation during therapy sessions (indicated
by single white blinking light). If not, you can try
calibrating the device again or increasing the
therapeutic intensity by clicking and holding the
button.
