Wireless Remote, TENS/EMS System:
The Hi-Dow Wireless TENS/EMS System is a battery operated wireless pulse generator that sends electrical impulses from a REMOTE control to RECEIVER (round) with ELECTRODES attached to them that are placed on the body to stimulate the nerves causing pain. When this happens, the nerves “FEEL” gentle electrical sensations instead of the pain. 
The Wireless REMOTE controls the ON/OFF of the system, the INTENSITY and the MODE functions of the RECEIVER. The RECEIVER with the electrodes attached to it adheres easily and firmly to the skin. 
Because the Hi-Dow system is Wireless - Needing No Lead Wires - you must use only Hi-Dow SNAP PIN Electrodes. Lead wire electrodes will not work with this Wireless system.

Intended Use:
To be used for the temporary relief of pain associated with sore or aching muscles of the lower back, arms, or legs due to strain from exercise or normal household and work activities.
To be used for the symptomatic relief and management of chronic, intractable pain and relief of pain associated with arthritis.
