patient. You do not need to hold the button down. Once you have pressed and released the
button, the current is delivered until you press and release the button again to stop the current.
The unit beeps once when you press the button to start the current, and beeps twice when you
press the button to stop the current.
While you are delivering current, the treatment timer counts up in seconds from zero. When
the current is stopped, the timer returns to zero. Press the button again to commence the next
time sequence. Continue in this way until treatment is completed.
Ground Probe: The ground probe is used to complete the circuit to allow flow of current
through patient tissue. The ground probe should touch the patient's skin at any location away
from the treatment point. As an alternative, you may also use a dispersive electrode as
explained below. With the ground electrode you do not need to hold the ground probe in
your hand during treatment. This is particularly convenient when treating in several different
places around one point.
Ground Electrode: You can use an electrode in place of the ground probe. Just unplug the
ground probe from its cable, attach a banana to pin adapter to the cable (this optional adapter
is available from your Dynatronics dealer), then attach an electrode to the pin. Place the
electrode on the patient at a site where it will not interfere with placement of the active probe
during treatment.
TREAT: Press and release the button
on the active probe to start current
delivery. The unit beeps once to
indicate current delivery has started.
When the active probe and a ground
probe touch the patient's skin, the
current is delivered to the patient.
Observe conductance by listening to the
audio tone.
TEST Mode: Press and release the
button again to stop delivery of current.
The unit beeps twice to let you know current delivery has stopped. The probe is now in
"Test" mode allowing you to continue monitoring conductance at any point desired. When
the probe touches the patient's skin, conductance continues to be measured and the audio
tone is produced. Press and release the button when you wish to return to the Treat mode.
NOTE: In Test mode during a microcurrent treatment, a small amount of current is delivered
to allow an impedance reading to be taken in order to show conductance. The current
delivered during Test mode is either 25 micro amperes or the micro amperage setting for the
treatment itself, whichever is less. For purposes of this measurement, current is delivered in
pulses of approximately 20 ms.

Cut the end off a cotton swab and insert it into
the tip of the cone. Saturate the cotton with
water or an electrolyte spray before treating.
