Ultrasound Therapy Module
Depending on the device configuration, the ultrasound therapy module is either an optional or a
standard device (part no. 025-0-1000-U or 025-0-1000-UV). With the Ultrasound probe either
Ultrasound therapies as also combination therapies with Ultrasound and current can be done.
!!
Note!
The ultrasound frequency can be changed to 1 or 3 MHz.
The frequency for pulsed mode is 100 Hz.
The selectable parameters are continuous or pulsed mode 1:1, 1:2, 1:5, 1:10 or
1:20.
The coupling status of the probe is shown by a LED on the probe's housing and
also as a graphical illustration on the display. The LED will be off in case of
insufficient coupling. The LED will be on in case of good contact.
As a standard setting the ultrasound power is shown in W/cm

on the display.
Warning!
Do not forget the contact gel!
The ultrasound probe has to be treated with care. External influences such as a
mechanical shock or impact can alter the characteristics of the ultrasound probe.
We recommend to carry out a visual examination at least once a year to check for
fissures that would allow liquids to soak in, as well as to make sure that the cables
and connectors are flawless.

Note!
Unless the ultrasound probe is coupled to the patient, no therapy time will pass.
When the probe is coupled again, the therapy time will resume. Hence, the
ultrasound probe can be removed during the treatment.
!!
Note!
The Ultrasound probe can be exchanged. After switching on the unit or
respectively after plugging the Ultrasound probe each probe will be calibrated
individually.
