hazardous situation which, if not avoided,
may result in minor or moderate injury
to the user or patient or damage to the
device or other property.
IMPORTANT SAFETY PRECAUTIONS AND WARNINGS
It is important that you read all the warning and precautions included in this manual. They
are intended to keep you safe, prevent injury and avoid a situation that could result in
damage to the product.
DANGER This product MUST NOT
be used in combination with the
following medical devices:
nInternally transplanted electronic
medical devices, such as
pacemakers.
nElectronic life-support equipment,
such as respirators.
nElectronic medical devices attached to the
body, such as electrocardiographs.
nConsult with your physician before using
this device, as it may cause lethal rhythm
disturbances in certain susceptible
individuals.
What is it?
Electrical Muscle Stimulation works by sending
electronic pulses to the muscle needing
treatment, causing the muscle to exercise
passively. It is a therapy derived from the
square waveform (ladder - shaped). Through
the square wave pattern, it is able to work
directly on muscle motor neurons. This therapy
has low frequency, and in conjunction with the
square wave pattern, allows direct work on
muscle groupings.
How EMS works?
EMS sends comfortable impulses through
the skin that stimulates 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. When the pulse ceases, the muscle
relaxes and the cycle is repeated. The goal
of electrical muscle stimulation is to achieve
contractions or vibrations in the muscles.
Normal muscular activity is controlled by the
central and peripheral nervous systems, which
transmit electrical signals to the muscles. EMS
works similarly but uses an external source (the
electrode device) with electrode pads attached
to the skin for transmitting electrical impulses
into the body. The impulses stimulate the
nerves to send signals to a specifically targeted
muscle, which reacts by contracting, just as it
does with normal muscular activity.
How MASSAGE works?
The massage stimulation program is a type of
low level EMS used to loosen tight muscles. Its
main function is to mimic manual massage to
promote relaxation and reduce muscle tension.
