the transmitter. It should light up for just a moment.
The higher the intensity, the brighter the test light will
be.
5. Watch the test light as you push the Constant button
on the transmitter. It should light up as long as the
button is pressed. However, as a safety feature, the
receiver will automatically stop the stimulation if the
Constant button is pressed for 12 seconds or longer.
6. Turn the Selector Dial on the transmitter clockwise
and then counterclockwise. The test light should glow
brighter with higher levels of stimulation and dimmer
with lower levels. When you change the intensity dial,
the number on the OLED screen will change as well.
Note:
The test light may not be visible if the intensity
level is set below level two.
