IONOSON-IF-Expert 1
1Introduction
With your IONOSON-IF-Expert, you have acquired a high-quality and extremely ver-
satile unit for stimulation current and ultrasound therapy.
The instrument will only show its true potential, however, if you are well informed
about its functions. For this reason, carefully read the
Operating Instructions and
familiarise yourself with the use of the instrument.
1.1 Instrument Description
IONOSON-IF-Expert is a two-channel stimulation current and ultrasound therapy
unit. You can apply all medium-frequency current modes (including the classic inter-
ference current) and additionally the low-frequency current modes HV and TENS. As
for ultrasound therapy, both transducers (2.5 cm2/ 5 cm2) of the IONOSON-IF-Expert
work with the frequencies 1 and 3 MHz. The unit can also be used for simultaneous
therapy (stimulation current and ultrasound in ONE treatment, page 33).
Therapy modes of IONOSON-IF-Expert may be accessed
directly or, by a proposed
treatment, via the indications menu (page 37). Moreover, the unit enables you to
memorise up to 25 individual treatment programs or current sequences (
potpourris ,
page 32).
All functions of IONOSON-IF-Expert are controlled by a microprocessor, which also
continuously monitors all important components and suppresses erroneously initi-
ated operating steps. After switching on, all instrument functions are checked dur-
ing an automatic self-test routine. The instrument complies with all current safety
standards.
The instrument meets the requirements of the EC directive concerning medical de-
vices (93/42/EEC) and is therefore CE-labelled.

Controls and Indicators
IONOSON-IF-Expert 3
2Controls and Indicators
As its LCD is divided in different function fields, IONOSON-IF-Expert allows for clear
and easy operation.
The plastic housing and the front panel protect the electronic components and sim-
plify cleaning.
Safety-related components are continuously monitored by the microprocessor, erro-
neously initiated operating steps are suppressed, a self-test routine is performed af-
ter switching on and possible malfunctions are displayed. For safety reasons, the
stimulation current output is automatically cut off in case of malfunction.
2.1 Function of Controls and Indicators
In the following section we will introduce the individual controls of IONOSON-IF-
Expert. The numbers in angle brackets refer to the
Instrument Overview at the be-
ginning of this manual.
2.1.1 Mains Module <1>
The mains module <1> with mains supply, fuses and mains switch
is situated at the rear side of the instrument.
For mains supply do only use the mains cable provided by the
manufacturer.
IONOSON-IF-Expert is switched on and off using the integrated
mains switch. After switching on, a self-test is automatically car-
ried out by the instrument (cf.
Notes on Operation on page 26).
Set the Line Voltage
After replacing the fuses, you can run the instrument with 230 V as well as 115 V
simply by using the rotatable fuse carrier at the mains module <1> (refer to section
Technical Data on page 56). The fuses are situated under the cover of the mains
module <1> in a fuse carrier.
Replace 1 A fuses with 2 A fuses, turn the fuse carrier by 180° and insert it again, so
that the “red window” of the mains module <1> reads “115 V”, after the cover
has been closed again.
Warning
Set the line voltage at the mains module to match the incoming line
voltage.

Controls and Indicators

2.1.2 Upper Status Bar<2>
The upper status bar <2> shows indications or some of the corresponding pa-
rameters selected. For example: G.
2.1.3 Display <3>
On the display <3>, you can select all of the instrument’s menus and parameters
on different levels except for the intensity. The selection is carried out with the data
selector <5>.
2.1.4 Lower Status Bar<4>
In the lower status bar<4>, messages and prompts are issued, e.g.:
PLEASE SELECT A FUNCTION .
2.1.5 Data Selector <5>
Use the data selector <5> to select the therapy pa-
rameters and to operate the instrument by means of
the cursor. After switching on the instrument, the
cursor is located at the current mode Gof the dis-
play <3>.
You can move the cursor to the other menu items by
turning the selector to the right or left. To select a
menu, simply press the selector.
To select a parameter, move the cursor to the respective field by turning the selec-
tor. After pressing the selector, the cursor will start flashing. You will then be able to
select the parameters by turning the selector and confirm the selected value by
pressing the selector again (cursor stops flashing). The modified values are displayed
in the upper status bar <2> or at the respective position of the display <3>.

2.1.6 Intensity Control Circuit I <6>
The intensity control circuit I <6> serves to set the therapy
dose (intensity) in circuit I in steps of 0.5 mA. When turning
up the intensity of intensity control circuit I <6> or inten-
sity control circuit II/dose <8>, the associated therapy
timer on the display <3> will be started as well.
Whenever you have to turn down the intensity control
circuit I to “0”, the following turn-down signal is displayed
in the lower status bar <4>:
Automatic output current switch-off
IONOSON-IF-Expert disposes of an automatic output current switch-off activated
in case the current flow of the electrodes is interrupted (electrode falls off, plug is
disconnected from patient lead etc.). The message CHECK ELECTRODES I will appear
on the lower status bar<4> and the current will be automatically turned down to
a minimum basic current in circuit I. After eliminating the error, the current in circuit
I will automatically be surged to the previously set value and the message will disap-
pear.
2.1.7 Pulse Indicator Circuit I <7>
The pulse indicator circuit I <7> serves to visually monitor the cur-
rent modes and intensities of circuit I. It flashes whenever a pulse is
generated in circuit I by the processor, even in case of 0 intensity. It
will stop flashing however when the intensity is automatically re-
duced by the therapy timer. After turning down the intensity of cir-
cuit I to 0 with the intensity control circuit I <6> the indicator will
start flashing again. When changing the polarity of monophase cur-
rents in circuit I (display <3>) the indicator will show how the inten-
sity increases or decreases automatically.
2.1.8 Intensity Control Circuit II / Dose <8>
The intensity control circuit II / dose <8> serves to set
the current intensity in circuit II in steps of 0.5 mA and the
ultrasound dose in steps of 0.1 W/cm2. When turning up
one of the two intensity controls circuit I <6> or inten-
sity control circuit II / dose <8>, the therapy timer on the
display <3> will be started as well.
Every time you have to turn down the intensity control
circuit II / dose to 0, the following message will be dis-
played in the lower status bar<4>:

Controls and Indicators
6 IONOSON-IF-Expert
Automatic output current switch-off
IONOSON-IF-Expert disposes of an automatic output current switch-off activated
in case the current flow of the electrodes is interrupted (electrode falls off, plug is
disconnected from patient lead etc.). The message CHECK ELECTRODES II will appear
on the lower status bar<4> and the current will be automatically turned down to
a minimum basic current in circuit II. After eliminating the error, the current in circuit
II will automatically be turned up to the previously set value and the message will
disappear.
2.1.9 Pulse Indicator Circuit II <9>
The pulse indicator circuit II <9> serves to visually monitor the cur-
rent modes and intensities of circuit II. It flashes whenever an pulse
is generated in circuit I by the processor, even in case of 0 intensity. It
will stop flashing, however, when the intensity is automatically re-
duced by the therapy timer. After turning down the intensity of cir-
cuit II to zero with the intensity control circuit II / dose <8>, the
indicator will start flashing again.
Note
Due to safety reasons increasing the ultrasound dose after the ultra-
sound has coupled (marker appears in the upper status bar <2>) is
only possible after prior turning down the dose with control circuit
II/dose <8>.
2.1.10 Patient Current Indicator <10>
The diode at the left side of the symbol is attrib-
uted to circuit I, the diode at the right to circuit II.
The flashing of the indicators depends on the
resistance in the two circuits.
In most cases the diodes start flashing exactly at the moment when the patient
starts to have a clear sensation of the current in the corresponding circuit.
If the indicator does not flash during treatment, you have to carry out a self-test
routine and observe whether or not the indicator flashes. If the indicator still does
not flash during treatment after the check, the accessories of the corresponding cir-
cuit should be checked and replaced if necessary.
2.1.11 Output Indicator <11>
The indicator tells you to be cautious when handling
the electrodes:
Warning! The patient lead connector <12> is under
voltage! Take care that the electrodes are by no
means touched after the current is turned up!

Controls and Indicators
IONOSON-IF-Expert 7
2.1.12 Patient Lead Connector <12>
The patient lead connector <12> serves to plug in the patient lead. You can plug
plate electrodes, adhesive electrodes or other types of electrodes into the patient
lead.
Patient Lead - Mode(s) of Attachment
The colours of the connectors facilitate easy and cor-
rect attachment of the electrodes to the two circuits
and to their polarity.
Colour of the inner circle:
red = circuit I, blue = circuit II
Colour of the outer circle:
red = anode (+), blue = cathode (-)
Type BF component, not connected to protective ground wire.
Warning
Take care that the electrodes are by no means touched after the cur-
rent is turned up!
2.1.13 Ultrasonic Transducer Connector <13>
The ultrasonic transducer is connected to the instrument by means of the ultra-
sonic transducer connector <13>. The transducer is automatically calibrated after
it has been connected or after switching on the instrument.
Replacing the ultrasonic transducer during treatment will not affect the selected
mode of treatment. The dose, however, will automatically be turned down to 0 and
has to be increased again when continuing the treatment.
If no transducer has been plugged in, the message Plug in head will appear in the
lower status bar<4>.

Ultrasonic Transducer
The ultrasonic transducer <11> (2.5 cm² and
5 cm²) works with the frequencies 1 MHz and 3
MHz. The transducer is automatically calibrated
after connecting or switching on the instru-
ment.
The transducer is watertight and can be used
for underwater treatment.
Automatic Coupling Confirmation
Both transducer and instrument have an optical coupling confirmation, which guar-
antees constant and efficient treatment. If the coupling to the tissue of the patient is
not efficient enough, the light at the transducer will start flashing. You can choose
between counting only the effective treatment time or running the timer independ-
ently of the coupling (Setup Menu).
Warning
The transducer contains a fragile ceramic piezo-resonator. Avoid
shocks to the surface and take special care that the transducer is not
dropped. Handling malpractice can change the physical characteristics
of the transducer!
2.1.14 Manual Release Key Socket <14>
The manual release key socket <14> serves to connect a
manual release key for manually triggering the current pulse or
as a therapy pause button. The use of a manual release key
may be appropriate when applying the current modes MT and
KOTS. To activate it, the function display must be at the follow-
ing position:
The manual release key can be used as a therapy pause button for all other current
modes. When pressing the release key, the current is switched off immediately. The
following symbol appears on the display <3> after pressing the therapy pause but-
ton:
You can turn up the current only after setting the intensity control circuit I <6>
and/or intensity control circuit II/dose <8> to zero. The therapy time is inter-
rupted as long as the unit is standing by.
2.1.15 VAC Socket <15>
The VAC socket <15> serves to connect to a vacuum applica-
tion unit PHYSIOVAC

2.3.2 Dual channel operation
For all current modes except IF:: you can select additional current modes (dual
channel operation) in circuit II .
2.3.2.1 For all current modes except IF and G
The current mode set in circuit I (except for G) can also be selected with the same
parameters in circuit II. AMF and MT can always be selected.
2.3.2.2 For the MT and KOTS current modes
The current mode set in circuit I can also be selected in circuit II, whereby individual
parameters can be set independently for both circuits. With circuits I and II, stimula-
tion can be either simultaneous or alternating. Carry out the following operational
steps:
(1) Select the desired current mode in both circuits.
(2) With the data selector <5>, first click on the selection field and turn
the selector to the left until the desired icon appears (e.g. for simultaneous
stimulation). The parameter R will acquire the appropriate value.
Simultaneous stimulation
Circuits I and II stimulate simultaneously with the same pa-
rameters. The polarity and ramp of the surge current can be
freely selected in each circuit.
To adjust the threshold time and threshold interval, carry out the operational steps
1-2 described above, and then proceed as follows:
(3) With the data selector <5>, first click on the selection field in circuit
I.
(4) In the new window, click on the selection field, turn the selector to the
right and select the duration of the surge interval.

Simultaneous stimulation can also be initiated with the manual release key. Carry
out the above-described operational steps 1-5, and then proceed as follows:
(3a) With the data selector <5>, first click on the selection field in circuit I.
(4a) In the new window, click on the selection field, turn the selector at least one
step to the right and confirm this.
(5a) In the same window, click on the selection field and turn the selector to the
left until the manual release key icon appears.
(6a) Leave the window via the button.
(7a) Insert the manual release key into the manual release key socket <14> at the rear
of the equipment.
The length of the surge currents in circuits I and II is determined by the pressure on
the manual release key.
If you have set up the manual release key in both circuits, then simultaneous stimu-
lation will also follow.
Alternating stimulation (continuous transition between circuits I and II)
Circuits I and II provide alternating stimulation, one directly after
the other.
A surge cycle follows, consisting of:
•Surge current in circuit I in the selected length
•No pause
•Surge current in circuit II in the selected length
•Pause for the selected length
To set the surge time and surge pause, carry out steps 1-6, described above.
Alternating stimulation can also be controlled with the manual release key. To do
this, carry out steps 1-2 and 3a-7a, described above.
Alternating stimulation (defined pauses between circuits I and II)
Circuits I and II provide alternating stimulation, with defined
pauses between the surges in circuits I and II.
The surge times and surge pauses are adjusted in circuit I. To do this, carry out steps
1-6, described above.
Alternating stimulation can also be controlled with the manual release key. To do
this, carry out steps 1-2 and 3a-7a, described above.
