Programs

)

 produce a combination of tingling or pulsing/ tapping sensations associated with muscle 

contractions.  In NMS a period of muscle contraction (Work) is alternated with a period of rest. 
 
Programs R, S and T are TENS programs.  
 
In program S, the output is Continuous. Intensity should be set so that there is a strong tingling feeling 
WITHOUT muscle contraction. Program S can be used until the pain relief effect starts to wear off – up to 
2 hours.  
 
In program T the stimulus is delivered in bursts: i.e. a group of pulses rather than a single pulse.  You 
should set intensity so that muscle contractions just start to appear, and use for not more than 60 mins.

• 

Press the Menu key. The Hz display will start to flash.  

• 

Use Menu +/- keys to adjust to the desired setting. 

• 

Press the Menu key to confirm the change and go to the next parameter. 

• 

After setting Timer, no parameters flash and settings are saved. If you only wish to change one 
parameter, you can confirm the settings and escape from the Menu by increasing Intensity above 
zero. If no key is touched for 6 seconds the settings will be saved and the  unit exits Menu.
