sure the combo lead is plugged into the correct output jack for the stim modality you
have selected.
3. Enter treatment parameters for the selected modality as instructed earlier in this manual.
4. Place the soundhead at the treatment site making good contact with the skin (be sure you
have applied conductive gel first). Raise the stim intensity to the desired level. If the
soundhead is in proper position and coupling is good, the patient will feel the current. If
the patient does not feel the current, check to be sure coupling is good and make sure you
have used ample conductive gel.
KEEP THE STIM INTENSITY LOW!
Set up Sound:
Continue to keep the soundhead in contact with patient skin during ultrasound setup.
1. The Sound indicator light must be green before setting up ultrasound parameters. Press
the Channel Toggle key, if needed, to select SOUND.

1. Press
START.
If you fail to set the intensity or ultrasound power before pressing START, the Power-
Intensity display will begin flashing, and you will be unable to start the treatment until
you set the intensity. Remember that you must set both the intensity for the stim
treatment and the power for the sound treatment.
NOTE: SAVE DEFAULTS. The default combination treatment includes ultrasound
with premodulated treatment for five minutes. The stim treatment parameters are derived
from the defaults for that modality You may change the default stim modality for
COMBO treatments to any of the stim modalities available with COMBO. You may also
set a new default treatment time, if desired.
To save new default settings, after setting up the treatment, press and hold the START
key for two seconds. At the end of two seconds, you will hear a beep indicating the
treatment parameters have been saved. If you changed any parameters for the stim
modalities during this treatment setup, those parameters will also be saved as the new
default settings for that modality. Any ultrasound parameters that are saved will apply
only to combo treatments—separate ultrasound treatments may have separate default
settings.
9. Press
STOP if it is necessary to stop a treatment before time has expired.
When the treatment time has elapsed, the current to the patient stops and a tone sounds
notifying you of the treatment end. Treatments in progress may be stopped at any time
using one of the following methods.
STOP: Press this key to stop all treatments at all channels.
