The iEnjoy™ Transcutaneous Electrical Nerve Stimulation (T.E.N.S.) / Electronic Muscle Stimulation (E.M.S.) Dual Channel / 8 Mode Massage Therapy Device is a Class 1 battery operated pulse generator that sends electrical impulses through the use of electrodes.

The device employs advanced massage therapy technology for minor muscle aches and pain relief.

The unit has two independent output channels that are independently controlled. Each output channel provides the user the ability to connect a pair of electrodes into each output channel. The Mode Settings (1 thru 8), Intensity Settings (1 thru 9), and Timer Settings (in 10 minute increments) are independently controlled by pressing the desired buttons on the front panel. Additionally, the unit is designed to prevent any accidental setting changes during its operation. Unless a deliberate pressing of one of the corresponding buttons takes place, no change will occur.
