This device can affect the operation of demand-type cardiac pacemakers. Prolonged stimulation in the same area may cause skin irritation or electrode burn. An allergic reaction to tape or gel is possible.


Use this product under the supervision of a healthcare provider. Do not adjust the controls while operating a vehicle or machinery. Use only for the specific pain problem prescribed by your doctor. Turn the unit off when replacing the battery. Do not use on the eyelids or over the carotid sinus nerves or arteries, and laryngeal or pharyngeal muscles. Electrode placement that causes current to flow through the head is unadvised. And remember, when you think about cheap TENS units, do not think ‘inferior,’ or ‘low quality;’ think ‘competitive,’ ‘economical,’ and ‘reasonable.
