change the upper and lower limits of the range chosen. If you set both displays to the
same value, the treatment will be delivered at that single pulse rate rather than sweep
through a range.
The lower limit in the sweep range is shown
here. In this example, this is the lower limit of
the default HIGH range for the PULSE RATE.
Use these arrow

the lower limit of

Press this toggle key to select RATE. The "Time" and "Intensity" displays then show the lower
and upper settings for the PULSE RATE range you have selected (High or Low). In the
example above, 80 Hz is the lower limit for the range and 120 Hz is the higher limit for the
range. Use the arrow keys beside each display to change either or both of these frequencies,
if desired.
NOTE: By setting both displays to the same value, you can deliver a treatment at a single
PULSE RATE rather than sweep through a range. For example, set both the upper and the
lower limits at "100" for a 100 Hz treatment.
When you are finished setting the pulse rate range, press the Time toggle key to return to
the Time display. After 10 seconds with no key presses, the Time display automatically
returns.
6. Change the treatment TIME, if desired.
If the Time LED is not lighted, press the Time toggle key to select Time. The default
time is displayed. Use the Time arrow keys to increase or decrease the treatment time.
The Time toggle key may also be used to select RATE if you wish to modify the pulse
rate settings as explained in step 5 above.
7. Raise the INTENSITY to the desired level.
Remember, when you increase intensity, current to the patient begins. Therefore, you
should proceed to press START immediately after setting the intensity to begin the
treatment timer.
Never use High Volt to treat any conditions which contribute to loss of sensation,
and never use High Volt to treat an area where the patient cannot feel the electrical
stimulation.
8. Press START.
Be sure to press Start to begin both electrodes or probes treatments. When you press
start, the treatment timer begins counting down. If you fail to set the
