• Relieve your pain by using the TENS Mode.
• TENS is a non-invasive, drug free method to control your pain by sending tiny electrical impulses through the skin. In many cases, this stimulation will greatly reduce or eliminate pain.
• Strengthen your muscles by using the EMS Mode.
• EMS is widely used in hospitals and sports clinics to treat muscle injuries, to re-educate paralyzed muscles, and to prevent atrophy in affected muscles.

Electrotherapy Programs:

• 4 TENS Modes:
  
• Burst
• Burst Rate adjustable from 0.5 - 5Hz, pulse width from 50-300µS, frequency fixed at 10Hz
  
• Normal
• Continuous stimulation with adjustable pulse rate & width
  
• Pulse Width Modulation Mode (Modulation 1)
• Pulse width decreases to 60% in one cycle, and increases back to original value in following cycle.
• Pulse rate, pulse width, and cycle time are adjustable.
  
• Pulse Rate Modulation Mode (Modulation 2)
• Pulse Rate decreases to 60% in one cycle, and increases back to original value in following cycle.
• Pulse rate, pulse width, and cycle time are adjustable.
  
• EMS Mode Specs
• Ramp Time:
• Adjustable from 1-6 seconds.
• Determines the time to reach set output level from zero, and from set output level to zero.
• On / Off Time:
• On time controls contraction time, adjustable from 1-60 seconds.
• Off time controls relaxation time, adjustable from 0-60 seconds.
  
• 3 EMS Modes:
  
• Synchronous (S)
• Synchronized stimulation of 2 channels.
• Ramp duration, ramp up, ramp down, pulse rate, & pulse width are all adjustable.
  
• Asynchronous/Alternate (A)
• As per Synchronous Mode except that stimulation of Channel 2 occurs when contraction of Channel 1 is complete.
  
• Delay (D)
• As per Synchronous Mode except that stimulation of Channel 2 begins after adjustable delay after Channel 1 stimulation begins.
