The therapy stings or feels uncomfortable.

• Turn off the device using the app or by double tapping the device firmly with your fingers.
• Remove the device and inspect the electrode, make sure all four electrode gel pads are in good condition. If there is a significant amount of exposed silver, we recommend changing electrodes.
• If your skin is dry, consider using a light moisturizer 30-60 minutes before placing Quell on your leg.
• Place the device and electrode back on your leg, making sure that there is complete contact between the electrode and your 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 a therapy session. If it is felt within the first five seconds, it is a good indication that calibration is set too high.
