The EasyMotionSkin also has a safety feature here. If an electrode is not fully placed on the skin during dynamic exercise, the current is selectively transferred. This “prickling” or “stinging” is particularly unpleasant at higher intensities. The EasyMotionSkin continually monitors the current and if this suddenly changes, the affected channel immediately reduces to 1% or half of its set intensity. Once it is repositioned, the affected channel can be manually connected. Adapt your dynamic movements to the possibilities of the system and use the belt supplied if required to avoid loosening during the workout session. A technical failure is very rare and is usually caused by a massive overstretching of the material or incorrect care. This can be easily tested: Lay the MotionSkin flat on a table and connect the Powerbox as if you were wearing the MotionSkin. Start the app, pair the PowerBox Now all channel displays are red. You are not currently wearing the MotionSkin and your skin cannot connect. Take the two electrodes of the relevant channel (example neck left & amp; right) and press the black areas directly onto one another. Now the display of the app should first switch to gray (measurement process) and then switch to green. In this way, you can quickly and easily test each channel yourself in case of doubt. If the channel does not switch to green during this test, please contact our Support .
