The unity of the displayed current amplitude depends on the previously selected current
waveform and can be expressed in mA, µA or V.
A treatment is started by adjusting the current amplitude, unless a surge program has been
selected. To start a surge program, push the Assist button and deactivate the pause symbol with
the central controller and the confirmation button [6].
11.2.12.c 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 applications. In CV mode the output current depends on the electrical contact with the
patient and can therefore vary. You can change the CC/CV setting in the parameter menu.
11.2.12.d Current polarity
When DC currents are used, the red terminal is the positive terminal and the black one the
negative terminal.
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.
11.2.13 Ultrasound power/Amplitude
The ultrasound Amplitude is adjusted with the central controller [5]. Push the channel button [3]
and adjust the Amplitude with the central controller.
• The ultrasound Amplitude can only be adjusted when the clock has been set.
The ultrasound Amplitude can be displayed in W or . You can change this setting in the
ultrasound parameter menu.
During treatment the displayed ultrasound Amplitude can vary around the set value, caused by
fluctuations in acoustical coupling. A blinking display indicates insufficient acoustical coupling.
11.3 Memory functions
The 600-series is equipped with a memory to store protocols. Push the Assist button [7] and
select store in the pop-up with the central controller [5]. Follow the instruction on the screen.
11.3.1 Protocols via Therapy Wizard
The 600-series provides a number of pre-programmed protocols available via Body Part or
Application. These protocols only serve as a guide and you should use your own expertise in
applying them.
A protocol consists of one or more treatment steps that are sequentially executed. Each
treatment step has its own current waveform, parameter settings and treatment time.
Electrotherapy protocols can constitute either single or dual channel applications. Prior to
loading a single channel protocol, the target channel must first be specified. When a single
channel protocol is executed, a completely different single channel protocol can be executed at
the other channel. It is also possible to link the current channels, which causes the protocol to
be executed on both channels. Dual channel protocols can only be loaded when the current
channels are linked.
11.3.1.a Loading a protocol
• In the Home menu, select Therapy Wizard with the central controller [5] and enter by
pushing the confirmation button [6]
• Select a protocol via Body Part, Applications or by a protocol number.
• Select a target channel in the Channel Selection menu. Select 1+2 if you want to link the
channels, causing the protocol to be run on both channels.
