Therapy
Make sure you initiate therapy only after the device
and electrode are properly placed on the calf.
I am trying to start therapy with the app (or
by 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 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 using the app or pressing
and holding the button.
The therapy stopped and the light is blinking
orange continuously.
A blinking orange light typically indicates poor
contact between the electrode and the skin. This
may occur because the device is not securely
placed on the leg or because the electrode is
dry. Check that the electrode is snapped in, the
electrode is in complete contact with the skin,
and the band is attached snugly (but not too
tightly) on the leg. Start therapy again. If the
problem recurs, remove the device and inspect
the electrode. Place the device back on the leg
and restart the therapy session. If the problem
persists, then replace the electrode.
The light is blinking white but I do not feel
anything.
The intensity may be too low. Use the app or press
and hold the button to increase the intensity until
you feel a strong but comfortable sensation.
Alternatively, calibrate the device again.

The device isn't automatically restarting.
If you are using the app, go to Settings and
Therapy Dose. If "Manual" is selected, you need
to manually restart therapy. With any other
selection (Regular, Low, or High Dose), therapy will
automatically restart.
You can check and change settings manually
by holding the device off your leg without the
electrode connected. Hold the button down for 10
seconds to toggle between settings.
1 white light = Manual. 5 white lights = Regular
The therapy stings or feels uncomfortable.
Turn off the device by using the app or clicking the
button 4 times. Remove the device and inspect
the electrode, make sure all four electrode gel
pads are in good condition. If your skin is dry then
consider using skin moisturizer. Place the device
and electrode back on your leg, making sure that
there is complete contact between the electrode
and the skin. Sometimes it is helpful to smooth
the electrode onto the skin first and then secure
the sports band. If the discomfort persists, then
replace the electrode.
If replacing the electrode doesn't help, you may
need to recalibrate. One way to check calibration
level is to see how long it takes to feel any
sensation during therapy session. If it is felt within
the first five seconds, it is a good indication that
calibration is too high.
I have leg cramps/muscle contraction during
therapy, or muscle soreness after use.
Confirm that the intensity is appropriate – strong
but comfortable. You can recalibrate. You may
also want to decrease the intensity, as long as it
remains strong.
Try the other leg. One leg may be more prone to
cramping or soreness than the other leg.
