Why is my device pulsing after wearing it for a few hours?

After  five hours of continuous wear or when you wake up from overnight use, Quell will deliver an alternate stimulation pattern to remind you to remove the device from the leg. It is important to air out your skin to prevent irritation. After  five hours of wear or when you wake up, you should remove the device from the leg for 15-30 minutes in order to air out  your skin.  You can place the device back on your leg after you have given your skin time to air out, or you can switch the device to your other leg.
