3.OPERATING INSTRUCTIONS
http://www.maytoyo.com
1.1 General Introduction
1.2 Medical Background
Thank you very much for using our Nerve Muscle Stimulator. For you use
this device safely, please read this user manual carefully before your first
use.
Please keep this user manual with your device for future reference.
This device is a portable electrotherapy device, featuring three therapeutic
modes: Transcutaneous Electrical Nerve Stimulator (TENS), Electrical
Muscle Stimulation (EMS) and Massage, which are used for pain relief and
electrical muscle stimulation. The stimulator sends gentle electrical current
to underlying nerves and muscle group via electrodes applied on the skin.
The parameters of the device are controlled by the buttons on the touch
screen panel. The intensity level is adjustable according to the needs of
the individual user.
EXPLANATIONOF TENS
HOW TENS WORKS
Transcutaneous Electrical Nerve Stimulation (TENS) is a noninvasive,
drug free method of controlling pain. TENS uses tiny electrical impulses
sent through the skin to nerves to modify your pain perception. TENS does
not work for everyone. However, in most patients it is effective in reducing
or eliminating the pain, allowing for a return to normal activity.
The TENS unit sends comfortable impulses through the skin that stimulate
the nerve (or nerves) in the treatment area. In many cases, this stimulation
will greatly reduce or eliminate the pain sensation the patient feels. Pain
relief varies by individual patient, mode selected for therapy, and the type
of pain. In many patients, the reduction or elimination of pain lasts longer
than the actual period of stimulation (sometimes as much as three to four
times longer). In others, pain is only modified while stimulation actually
occurs.

EXPLANATIONOF EMS
Electrical Muscle Stimulation (EMS) 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. This device has low frequency and in conjunction with
the square wave pattern allows direct work on muscle groupings. This is
widely used in hospitals and sports clinics for the treatment of muscular
injuries and for the reeducation of paralyzed muscles, to prevent atrophy
in affected muscles and improving muscle tone and blood circulation.
HOW EMS WORKS
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. When the pulse
ceases, the muscle relaxes and then this cycle is repeated until therapy is
completed.
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
stimulator) with electrodes 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.
1.3 Indication for use (IFU)
TENS:
The device is designed to be used for temporary relief of pain associated
with sore and aching muscles in the shoulder, waist, back, neck, upper
extremities (arm), lower extremities (leg), abdomen and bottom due to
strain from exercise or normal household work activities.

EMS:
The device is designed to be used to stimulate healthy muscles in order to
improve or facilitate muscle performance.

4. CLEANING AND CARE
4.1 Tips for Skin Care
Follow these suggestions to avoid skin irritation, especially if you have
sensitive skin:
1. Wash the area of skin you will be placing the electrodes on with soap.
Rinse thoroughly and dry the area completely before and after placing
electrodes.
2. Excess hair may be clipped with scissors; do not shave stimulation area.
3. Many skin problems arise from the “pulling stress” from adhesive patches
that are excessively stretched across the skin during application. To prevent
this, apply electrodes from center outward; avoid stretching over the skin.
4. To minimize “pulling stress”, tape extra lengths of lead wires to the skin in
a loop to prevent tugging on electrodes.
5. When removing electrodes, always remove by pulling in the direction of
hair growth.
6. It may be helpful to rub skin lotion on electrode placement area during
treatment down time when you are not wearing electrodes.
7. Never apply electrodes over irritated or broken skin.
4.2 Cleaning the Device
1. Clean the device after use with a soft, slightly moistened cloth.
2. Do not use any chemical cleaners or abrasive agents for cleaning.
4.3 Electrodes
.
1. Use this device only with the leads and electrodes provided by the
manufacturer.
2. Check your electrode pads before every use. Replace them if needed.
Reusable electrode pads can cause slight skin irritation, lose adhesion
properties and deliver less stimulation if overused.
3. The ordering information of the electrodes pads: Available for purchasing
on Amazon, or other e-commerce platforms. But it specifies the manufactur-
er of the electrode pads, the manufacturer is the best choice for you. Be free
to contact the seller if you need.
4. The electrode pads type: It is a kind of hydrogel and medical silicone.

TO REMOVE YOUR ELECTRODES:
1. Lift the corner of the electrode and gently remove it from the skin.
2. It may be helpful to improve repeated electrode application by spreading a
few drops of cold water over the adhesive side and turn the surface up to air
dry. Over saturation with water will reduce the adhesive properties.
3. Between uses, place the electrodes back onto the protective sleeve and
insert them into the re-sealable bag and store in a cool dry place.
CAUTION:
1. Do not pull on the electrode wire. Doing so may damage the wire and
electrode.
2. The electrodes should be discarded when they are no longer adhering to
the skin.
4.4 Cleaning the Electrode’s Cords
Clean the electrode cords by wiping them with a damp cloth.
Coating then lightly with talcum powder will reduce tangles and prolong their
life.
4.5 Maintenance
1. Maintenance and all repairs should only be carried out by an authorized
agency. The manufacturer will not be held responsible for the results of
