Introduction
The Interferential 960 provides 4-pole and 2-pole Interferential
electrotherapy only.
The Multidyne 970 provides a complete range of low and medium
frequency waveforms (including Interferential) for electrotherapy and
electro-diagnostics.
Indications for use
Therapeutic voltage and current waveforms may be applied to a wide range
of conditions with successful outcomes. These include acute and subacute
traumatic and inflammatory conditions, chronic rheumatoid and arthritic
conditions, and for pain relief.
Precautions
The therapist must be aware of the following precautions and potential
hazards.
Simultaneous connection of a patient to high frequency surgical equipment
may result in burns at the site of the stimulator electrodes and possible
damage to the stimulator itself.
Operation in close proximity (less than 1 metre) to shortwave or microwave
therapy equipment may produce instability in the stimulator output.
Consideration must be given to the current densities for any electrode used
with the Multidyne 970 Unit. Current densities greater than 2 mA rms/cm
2
are not recommended because of the risk of burning. All the standard EMS
conductive rubber electrodes may be used up to the maximum output of
the unit without exceeding this figure. When using other electrodes, the
maximum safe output current should be assessed before use. First
estimate the effective contact area of the electrode in square cm, and then
apply the following formula: -
rms output current (mA) = Area of electrode (cm
2
) x 2
The ratio of the rms to the peak current for the different operating modes is
given in the technical specification section of this manual.
The output indication on the LCD shows the peak output voltage or the
peak output current in mA depending upon the selected mode of operation.
When using direct current, extreme care must be taken to ensure the
patient's safety from electrochemical burning. In particular, care must be
taken to avoid uneven pressure on the electrodes causing high local

Interferential 960/Multidyne 970
8
current density. Electrodes must not be applied where there are cuts or
abrasions.
Contraindications
Acute sepsis, due to the risk of spreading infection.
Tumours, due to the risk of increased growth or metastatic activity.
Pregnancy, do not treat the lower abdomen, back or pelvis.
Menstruation, do not treat lower back or abdomen due to risk of increased
bleeding or pain.
Cardiac conditions, do not treat the chest area or near the cervical
ganglion.
Cardiac pacemakers, especially demand type, or any other implanted
electronic device, unless specialist medical opinion has first been obtained.
Febrile conditions
Large open wounds in treatment area
Dermatological conditions in treatment area
Thrombosis
Hypersensitivity or fear of electrical treatments
Any patient who cannot understand the nature of the treatment, for
example, young children, very old or senile patients who cannot report back
adequately or understand the potential dangers. This may apply equally to
persons who do not speak the same language as the therapist.
Severe hypotension/hypertension, do not treat in the region of the lower
cervical spine.
If in doubt the patient's physician should be consulted.
Electrodes should never be placed so that the applied current crosses
the chest.

Installation
Upon receipt, check for any visible damage which may have occurred in
transit. If any signs of damage are found then retain all packing material
and inform the carrier and the Company or its agent from whom the unit
was purchased.
The Interferential 960/Multidyne 970 must only be used with an EMS
SLA9000 power supply (as supplied with the unit). Units fitted with an
internal rechargeable battery may be used powered by the battery only.
The Interferential 960/Multidyne 970 unit is supplied with four medium-
sized electrotherapy electrodes with their associated patient lead. Plug the
patient lead into the socket on the front of the unit and connect the
electrodes to the yellow and blue cables. The plug has an arrow and the
word ‘top’ embossed on it to aid correct orientation.
Operation of the unit in close proximity (less than 1 metre) to shortwave
therapy equipment or radio-frequency mobile communication equipment
could result in the output of the Interferential 960/Multidyne 970 being
affected.

Standard user interface functions
Throughout the operation of the Interferential 960/Multidyne 970 the
various modes and parameter settings are all accessed and changed by
pressing the graphic buttons on the LCD touchscreen.
The rotary control is used to increase and decrease the stimulation
intensity.
In 4-pole interferential mode it controls the overall stimulation intensity, in
all other stimulation modes it is possible to independently control the levels
of channels A and B by pressing and holding the relevant selection button.
The menu button is used to exit from the current screen or to select the
menu option highlighted.
