EMS stimulates motor nerves and produces muscle contractions. The appropriate mode depends on your goal, health and placement. Read our TENS vs EMS guide before selecting a mode.Independent Dual ChannelsChannels A and B can be adjusted separately, allowing different comfortable intensity levels on two areas during the same session. Independent A/B intensity does not mean independently selectable programs or simultaneous TENS and EMS operation. Follow the manual for supported settings and placements. Never position electrodes so current passes across the chest.How to Use the TENS Unit Charge the unit and connect the lead wires while the device is switched off. Apply pads to clean, dry, intact skin near the intended area. Select the appropriate mode and begin at the lowest intensity. Increase gradually until the sensation is strong but comfortable, never painful. Switch the unit off before moving or removing the pads.
