Introduction
The Interferential 960 provides Interferential 4-pole and 2-pole and Medi-
Wave 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
Voltage and current waveforms may be used to provide muscle stimulation
and relief from musculoskeletal pain.
Muscle stimulation may be used for muscle strengthening and rehabilitation
in otherwise healthy subjects recovering from surgery, for muscle
strengthening for critically or chronically ill patients or to (re)train weak or
ineffective muscles.
Pain relief may be appropriate post-surgery during rehabilitation, or for
relief from chronic conditions such as osteoarthritis.
Precautions
See also appendix B “Technical Specification”.
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/cm2
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 (cm2) x 2

Interferential 960/Multidyne 970
8
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
current density. Electrodes must not be applied where there are cuts or
abrasions.
Modification of the EMS960/970 is not permitted and may result in a
hazardous situation.
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, across the heart or near
the cervical ganglion – may cause cardiac fibrillation.
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, eg.
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.

Interferential 960/Multidyne 970

Electrodes should never be placed so that the applied current goes
across or through the head, eye, front of the neck (especially the
carotid sinuus), upper back or chest. Electrodes must never cover the
mouth.

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). A power cord
appropriately rated/approved for the country of use must be used.
The SLA9000 power supply must only be connected to a mains supply with
a protective earth conductor. If the integrity of the earth connection is in
doubt, do not connect it to the mains supply (risk of electric shock with type
B applied parts). The unit must not be positioned in such a way that the
mains plug cannot easily be unplugged – the mains plug is the main
disconnect device.
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.
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.
Permissible environmental conditions of use:
Temperature 10 to +35°C
Relative humidity 10 to 80%
Atmospheric pressure 500 to 1060hPa
Permissible environmental conditions of transport and storage:
Temperature -10 to +35°C
Relative humidity 5 to 95%
Atmospheric pressure 500 to 1060hPa

Standard user controls
Throughout the operation of the Interferential 960/ Multidyne 970 the
various modes and parameter settings are all accessed and changed by
touching the relevant buttons displayed on the touchscreen.
The rotary control is used to increase and decrease the stimulation
intensity when the TFT is showing a set-up screen. It can also be used to
safely stop a treatment by turning it all the way anticlockwise.
On most display screens touching the back arrow icon in the top left corner
will return the user to the last screen displayed, and touching the house
icon in the top right corner will return the display to the main Home screen.
Stimulator set-up
Touching the ‘Interferential’ button on the 960 Home screen will open this
screen –
At the bottom of most screens is the status bar.
The status bar shows the current power source and the battery status (if
installed).
If the unit is fitted with a rechargeable battery pack, the battery symbol will
be shown in the status line. The symbol is shaded green to show the
current charge state of the battery. If the battery is charging the green
shading will pulse. To conserve battery life, the unit will automatically turn
down the TFT backlight after 1 minute and power itself down completely
after 3 minutes if there has been no operator activity and the unit is running
off the battery.

System settings
Touching the System Settings button at the bottom of the Home screen
takes you to the System settings screen.
The Display button takes you to a screen where you can adjust the display
brightness using up/down buttons.
The Sound button takes you to a screen where you can adjust the pitch
and volume of the audio.
Language allows you to change the display language to any that are
installed in the unit (English, French, German, Spanish and Italian as
standard).
The About button displays info such as serial number and software version.
‘Help’ brings up an embedded text version of this user manual.
‘Clinic’ allows you to enter a name label for the machine which will be
displayed at the top of all screens.
‘Maintenance’ is designed for service engineers and needs a pass code to
enter.

User programs
The Interferential 960/Multidyne 970 can store up to 16 user defined set-
ups. Touch the User Programs button in the Home screen or in any
stimulation set up screen.
A screen will appear with a scrollable list of program slots – the active one
is highlighted in the middle. Touching ‘Save’ will store the settings from the
last open set up screen to this slot – if the slot isn’t empty a pop-up window
will appear asking you to confirm or cancel the save process (to prevent
unintentional over-writing of a previously saved program).
To recall a program simply touch its program slot button and a set up
screen will open showing the previously stored parameters.
The ‘Notes’ button in any user program set-up screen opens a qwerty style
keypad that allows you to save memo information about the program – the
first 30 characters recorded will be displayed as the title of that user
program.
