To Select Parameters for Programs
To Initiate Press Set button while device is on in the appropriate program option. Display will show
what Program is currently selected.
To Toggle Press the Set button again to toggle through the parameters.
To change Use the Channel 1 or Channel 2 Intensity buttons to change the parameters.
To Exit Press Mode button. Automatic exit will happen after 10 seconds and display the
Treatment Screen.
