5.2.1.8. CC/CV mode

Depending on the selected current waveform, the
electrotherapy channels can be used in the Constant
Current or Constant Voltage mode. It is advised to
use the CV mode with dynamic electrode applica-
tions. In CV mode the output current depends on
the electrical contact with the patient and can there-
fore vary. You can change the CC/CV setting using
button [13] and the central controller [16].

5.2.1.9. Current polarity

When DC currents are used, the red terminal is the
positive terminal and the black one the negative ter-
minal. To manually change the polarity, press but-
ton [13] and select or
ler [16]:
: Standard
: reversed
Manually changing the polarity during a treatment
will result in a current decaying to 0, followed by a
current with the opposite polarity, rising to a value
equal to 80% of the previous value.
To activate automatic polarity reversal of the The High
voltage and Microcurrent waveforms, select
with button [9] and the central controller [16]:
: alternating
: not alternating
With the Interrupted DC current waveform it is not
possible to reverse the current polarity.

5.2.1.10.Ultrasound intensity

The ultrasound intensity is adjusted with intensity
controller [18]. The ultrasound intensity can only be
adjusted when the clock has been set.
The ultrasound intensity can be displayed in W or
. You can change this setting using button [13]
and the central controller [16].

5.2.1.11.Emergency stop

Pressing buttons [12] and [13] simultaneously will
terminate all active treatments.
