Error E80 - Overcurrent Error 

Appears when the current level spikes (e.g., the 
electrode is partly detached from the treatment area 
or moved out of position). 
 Press “Enter” to return to the waveform screen. Check 
the electrodes. Check the electrode cable connections 
to make sure that they are connected. Make sure both 
electrodes are attached to the cables and to the 
patient. Try fresh electrodes and or cables to resolve 
this problem.  

Press the “Start/Pause” key and to restart the 
treatment and return to the previously set intensity. 

Or press the “Stop” button to stop the treatment and 
return to the treatment screen. Pressing the 
“Start/Pause” key will restart the treatment at the 
beginning. You will need to press “Enter” to begin to 
increase the intensity and start the treatment. 
If the above does not correct the error. Remove the 
electrode cables from the unit. Then turn the unit Off 
and turn it back ON and retry the treatment. If this 
does not correct the problem, the unit requires 
servicing. Report the error to service provider to assist 
with hardware troubleshooting.

Error E85 – Current too low

 

Check the electrodes. Resume the treatment by doing 
the following: 
Press “Enter” to return to the waveform screen. Check 
the electrodes. Check the electrode cable connections 
to make sure that they are connected. Make sure both 
electrodes are attached to the cables and to the 
patient. Try fresh electrodes and or cables to resolve 
this problem.  

Press the “Start/Pause” key and to restart the 
treatment and return to the previously set intensity. 

Or press the “Stop” button to stop the treatment and 
return to the treatment screen. Pressing the 
“Start/Pause” key will restart the treatment at the 
beginning. You will need to press “Enter” to begin to 
increase the intensity and start the treatment. 

If the above does not correct the error. Remove the 
electrode cables from the unit. Then turn the unit Off 
and turn it back ON and retry the treatment. If this 
does not correct the problem, the unit requires
