AJUSTING THE C NTR LS USING
MANUAL ADJUSTMENTS
Choose the desired mode by pressing the mode Mode Button
There are 3 modes available Constant, Synchronous and Alternate.
Constant
Constant or normal is stimulation based on setting value.
Only pulse width, pulse rate and timer are adjustable in this
mode.
Synchronous
Stimulation of both channels occurs synchronously. The
"ON" time including "Ramp Up" and "Ramp own" time.
Therefore, the setting of ON Time should be no less than
two times of the Ramp Time in this mode.
Alternate
The stimulation of CH2 will occur after the 1st contraction
of CH1is completed. In this mode, the setting of the ON
Time should be no less than two times of the Ramp time.
The Off Time should be Equal or more than the On Time.
When you have chosen the desired mode now press the SET button, toggle
through each parameter, you can enter the required setting. You can
change the value by pressing the Increment UP and own controls when
the value is flashing.

CH SING THE C RRECT PARAMETERS
IN MANUAL ADJUSTMENT M DE
With all muscle stimulators, it is important that the frequency, pulse width and
work rest times are set correctly, to both maximise the results and use the device
in a safe and responsible manner.
Frequency Selection
15-25Hz (pulse per second)
The range of frequencies helps to promote muscle endurance and conditioning.
25-50Hz (pulse per second)
This frequency range would be selected for muscle strengthening and muscle
bulk.
50-120Hz (pulse per second)
This range of frequency is used for strengthening, re-education and spasticity.
Using higher frequencies 50Hz plus requires only short periods of treatment time
as muscle fatigue will occur very quickly.
Pulse width selection
The pulse width selection is dependent on the depth of penetration and targeted
muscle group. For example, the more superficial the muscle the lower the pulse
width; see examples below:
Hand / foot muscles 80µs – 100µs
AB Abdominal muscles 80µs – 100µs
Leg muscles 250µs – 300µs
Arm muscles 150µs – 250µs
For strengthening protocols of all large muscle groups 300µs may be best

Work est (Contraction / elaxation) Times
When setting the work / rest times it is important that the rest time is at least
equal to the work time; for example 4 seconds on time 4 seconds off time.
For weaker muscles a larger rest time will be required for example 4 seconds on
This allows for muscle recovery and reduces muscle fatigue.
amp Time
The ramp time is the amount of time taken for intensity to reach its work time
phase. Typical settings would be usually 2-4 seconds ramp up time and 1-2
seconds ramp down time. For a stronger stimulation, increase ramp up time to
maximum 8 seconds.
Stimulation modes
• Continuous mode – device runs continually
• Synchronous mode – output from both channels occurs in sync
• Alternate mode – The stimulation of channel 2 will occur after the first
contraction of channel 1
Examples of treatment settings

INTR DUCTI N
This EMS unit is used for muscle stimulation. The device is provided with
controllable output channels, each independent of the other. A pair of electrodes
can be connected to each output channel. An independent switch controls the
intensity level and settings.
EXPLANATION OF EMS
Electrical Muscle Stimulation is an internationally accepted and proven way of treating
muscular injuries. It works by sending electronic pulses to the muscle needing treatment;
this causes the muscle to exercise passively.
It is a product derived from the square waveform, originally invented by John Faraday in
1831. Through the square wave pattern it is able to work directly on muscle motor neurons.
The EMS has low frequency and this in conjunction with the square wave pattern allows
direct work on muscle groupings. This is being widely used in hospitals and sports clinics
for the treatment of muscular injuries and for the re-education of paralyzed muscles, to
prevent atrophy in affected muscles and improving muscle tone and blood circulation.
HOW EMS WO KS
1. Relaxation of muscle spasms
2. Prevention or retardation of disuse atrophy
3. Increasing local blood circulation
4. Muscle re-education
5. Immediate post-surgical stimulation of calf muscles to prevent venous thrombosis
6. Maintaining or increasing range of motion
The EMS units send comfortable impulses through the skin that stimulate the nerves in the
treatment area. When the muscle receives this signal it contracts as if the brain has sent
the signal itself. As the signal strength increases, the muscle flexes as in physical exercise.
Then when the pulse ceases, the muscle relaxes and the cycle starts over again,
(Stimulation, Contraction and Relaxation.) Powered muscle stimulators should only be
used under medical supervision for adjunctive therapy for the treatment of medical
diseases and conditions.

EMS CAUTI NS
1. Safety of powered muscle stimulators for use during pregnancy has not been
established.
2. Caution should be used for patients with suspected or diagnosed heart problems.
3. Caution should be used for patients with suspected or diagnosed epilepsy.
4. Caution should be used in the presence of the following:
a. When there is a tendency to hemorrhage following acute trauma or fracture;
b. Following recent surgical procedures when muscle contraction may disrupt the healing
process;
c. Over the menstruating or pregnant uterus; and
d. Over areas of the skin which lack normal sensation.
5. Some patients may experience skin irritation or hypersensitivity due to the electrical
stimulation or electrical conductive medium. The irritation can usually be reduced by
using an alternate conductive medium, or alternate electrode placement.
6. Electrode placement and stimulation settings should be based on the guidance of the
prescribing practitioner.
7. Powered muscle stimulators should be kept out of the reach of children.
8. Powered muscle stimulators should be used only with the leads and electrodes
recommended for use by the manufacturer.
9 riving, operating machinery, or during any activity in which involuntary muscle
contractions may put the user at undue risk of injury.
C NTRAINDICATI NS
Electrical stimulators should not be used on patients with cardiac demand pacemakers.
ADVERSE REACTI NS
Skin irritation beneath the electrodes have been reported with the use of electrical
stimulators. If irritation occurs, discontinue use and consult your medical professional.
Sensitive skin electrodes are available which elminate skin irritations..

WARNINGS
It is imperative that patients read and understand the warnings and precautions before
using this device. o not allow your machine or electrodes to be used by anyone else, as
they are designed for single patient use only. It is recommended that proper medical advice
on the use of EMS is sought from a Qualified Practitioner (Physiotherapist, octor or
Nurse) prior to use, in order to ensure safe and effective treatment. If you are taking any
medication please carry on as normal but seek advice from your octor/Healthcare
Professional before using the device.
1. The long-term effects of chronic electrical stimulation are unknown.
2. Stimulation should not be applied over the carotid sinus nerves, particularly in patients
with a known sensitivity to the carotid sinus reflex.
3. Stimulation should not be applied over the neck or mouth. Severe spasm of the laryngeal
and pharyngeal muscles may occur and the contractions may be strong enough to close
the airway or cause difficulty in breathing.
4. Stimulation should not be applied transthoracically in that the introduction of electrical
current into the heart may cause cardiac arrhythmias.
5. Stimulation should not be applied transcerebrally.
6. Stimulation should not be applied over swollen, infected, or inflamed areas or skin
eruptions, e.g., phlebitis, thrombophlebitis, varicose veins, etc.
7. Stimulation should not be applied over, or in proximity to, cancerous lesions.
WA NING! PATIENTS WITH PACEMAKE S MAY NOT BE T EATED WITH EMS
• o Not use during pregnancy except during labour

ELECTR DE INSTRUCTI NS
Turn Stimulator OFF before applying or removing electrodes
Application
1. Skin site must be very clean and dry. irty, flaky or oily skin will prevent electrodes from adhering to
the skin. If necessary, trim excess hair with scissors. If skin is oily wipe down with an alcohol or
electrode skin prep prior to application. Be sure to wash hands before handling electrodes.
2. Remove electrodes from bag and reseal bag to protect remaining electrodes.
3. Grasping a tiny edge of the electrode, peel and remove electrode from the protective plastic liner.
Save liner for electrode storage.
4. Place electrode onto skin treatment site (as recommended by your clinician) by firmly applying from
the centre of the electrode to the outer edges. Adhesion improves when electrodes reach skin
temperature.
5. If gel appears oversaturated with excessive moisture or perspiration, allow the electrode to air-dry
in a refrigerator with the gel side facing up until the gel regains its tack. If the gel appears dry, try
adding a few drops of water to the gel and allow to rest in a dust-free environment until the gel
regains its tack.
emoval and storage
1. Lift a corner of the electrode and slowly peel the electrode off the skin, touching the adhesive gel as
little as possible.
2. Place the electrodes back onto the saved protective plastic liner.
3. While grasping the electrodes connector with one hand, use the other hand to gently twist and
disconnect the lead wire pin from the electrode connector. .
4. Return the electrodes back into the storage bag and reseal tightly to prevent dry-out.
5. Store at room or cool temperature and keep out of direct sunlight.
6. The life of the electrode varies depending on skin conditions, amount of use, storage and climate.
Electrode life may be extended by carefully following the application, removal, and storage
instructions.
Caution
1. O NOT place electrodes on broken skin. If skin irritation develops discontinue use. Consult
physician. Replace electrodes when they do not adhere or when treatment becomes uncomfortable.
2. O NOT use unit while driving or operating machinery
3. O NOT wear electrodes when showering, bathing or swimming
4. O NOT apply electrodes across the head or across the heart or on the front of your neck.
5. Keep electrodes separated during treatment

ELECTR DE PLACEMENT
There are many questions as to the optimal position for the adhesive electrodes
during an electro-stimulation session. Consequently, we are going to try to
answer your various question by setting out below the effective positions for the
sport (rectangular) and beauty (round) electrodes for different areas of the body.
We are definitely not trying to give an anatomy class here but is is necessary to
understand the whole muscle system to get a more precise grasp of the human
muscle system.
The muscle map of the human body comprises more than 600 items with wild
names such as manducatory muscles or mime muscles, the thenar muscle, or
even the gluteal muscles.
