1. INTRODUCTION
FOREWORD
TU2124 is a TENS and EMS machine which
is highly effective in relieving pain, different
programs suit different parts of the body
and pain. Before using, please read all the
instructions in this user manual carefully and
keep it safe for future reference.
HOW DOES IT WORK?
TENS - Transcutaneous Electrical Nerve
Stimulations Transcutaneous
Transcutaneous Electrical Nerve Stimulations
(TENS) are safe, non-invasive, drug-free
methods of pain management. TENS is
currently one of the most commonly used forms
of electro-analgesia. The TENS device relieves
pain by sending small electrical impulses
through electrodes placed on the skin to
underlying nerve fibers.
EMS- Electrical Muscle Stimulation, also known
as powered muscle stimulator (PMS).
EMS is an electrically powered device that
repeatedly contracts muscles by passing
electrical currents through electrodes contacting
the affected body area.

2
The intended uses include:
TENS:
- Temporary relief of pain associated with
soreness.
- Aching muscles in shoulder, waist, back, neck
and upper extremities (arm).
- Lower extremities (leg) pain caused by
exercise strain.
- Lower extremities (leg) pain caused by normal
household work activities.
EMS:
- Improve or facilitate muscle performance.

WARNINGS:
DO NOT USE THIS UNIT UNDER THESE
CONDITIONS:
Consult with your physician before using
this unit. This unit may cause lethal rhythm
disturbances in certain susceptible individuals.
If you have had a surgery recently, the
stimulation may disrupt the healing process.
Before using your unit, inspect these things.
1. Cord is not broken.
2. Pad gel is not damaged.
3. Electrode cord connection is not broken.
4. Unit is intact and working.
5. There is no battery leakage.
DO NOT USE UNDER THE FOLLOWING
CONDITIONS
● Pregnantwomen.
● Donotuseitonchildrenorinfantsbecause
the device has not been evaluated for pediatric
use.
● Keepoutofthereachofyoungchildren
because the electrode cord could cause
strangulation.
● Personsincapableofexpressingtheir
thoughts or intentions.

4
● Persons incapable of operating the unit by
themselves.
● Usewithcautionifyouhaveatendencyto
bleedinternally,suchasfollowinganinjuryor
fracture.
● Ifyou’resuspectedordiagnosedwith
heart disease, you should follow precautions
recommended by your physician.
● Ifyou’resuspectedordiagnosedwith
epilepsy, you should follow precautions
recommended by your physician.
● Usewithcautionifstimulationisappliedover
the menstruating uterus.
● Useofaccessoriesandcablesotherthan
those specified or provided by the manufacturer
of this equipment could result in increased
electromagnetic emissions or decreased
electromagnetic immunity of this equipment and
result in improper operation.
● PortableRFcommunicationsequipment
(including peripherals such as antenna cables
and external antennas) should be used no
closer than 30cm (12 inches) to any part of the
ME EQUIPMENT, including cables specified
by the manufacturer. Otherwise, it may result
in degradation of the performance of this

5
equipment.
● Useofthisequipmentadjacenttoorstacked
with other equipment should be avoided
because it could result in improper operation. If
such use is necessary, this equipment and the
other equipment should be observed to verify
that they are operating normally.
DANGER:
NEVER APPLY THE PADS TO THESE BODY
AREAS:
● Thehead,themouth,oranyareaofthe
face.
● Theneckoranyareaofthethroatbecause
this could cause severe muscle spasms
resulting in closure of the airway, difficulty in
breathing, or adverse effects on heart rhythm or
blood pressure.
● Donotuseitneartheheart,orongenital
area.
● Bothsidesofthethoraxsimultaneously
(lateral or front and back), or across your chest
because the introduction of electrical current
may cause rhythm disturbances which could be
lethal.
● Onthecalvesofbothlegsoracrosstheleft

6
and right limbs at the same time, because this
may cause cardiac disturbance.
● Openwoundsorrashesoroverswollen,
red, infected or inflamed areas or skin
eruptions (such as varicose veins, phlebitis,
thrombophlebitis and thrombosis), or on top of
or close to cancerous lesions, or over areas of
skin that lack normal sensation.
● Don'tusethedeviceifyouuseahigh
frequency surgical ME EQUIPMENT
simultaneously. Such use may result in burns
and possible damage to the device.
● Operationincloseproximity(e.g.1m)toa
shortwave or microwave the ME EQUIPMENT
may produce instability in the device output.
● Theapplicationofelectrodesnearthethorax
may increase the risk of cardiac fibrillation.
NOTICE:
Caution should be used in the presence of the
following:
●When there is a tendency to hemorrhage
following acute trauma or fracture.
●Following recent surgical procedures when
muscle contraction may disrupt the healing
process.

7
●Over area of the skin which lack normal
sensation.
●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.
●Electrode placement and stimulation settings
should be conducted under the guidance of the
prescribing practitioner.
●Do not attempt to move the electrode pads
while the device is ON or operating.
●Any electrodes that have current densities
exceeding 2mA/cm2 may require special
attention of the operator.
●Do not use the device around the heart,
on the head, mouth, genitals or blemished
skin areas, on the front of the neck, or from
electrodes placed on the chest and the upper
back or crossing over the heart.
● Usecautioniftheuserhasatendencyto
bleedinternally,suchasfollowinganinjuryor
fracture.

9
origin (i.e. appendicitis, Hepatitis), including
headache.
● Thedeviceisanasymptomatictreatment
and, as such, suppresses the sensation of
pain that would otherwise serve as a protective
mechanism.
PRECAUTIONS REGARDING THE PADS
● Donotmovethepadstoanotherlocation
while the unit is on.
● Therapywon'tworkwithjustonepad.You
MUST USE TWO PADS at the same time.
● Makesurethecomponentsareconnected
well and the pads are fixed on the part of the
body you wish to treat or the therapy may not
be effective.
● Padshouldnottouchanymetalobject,such
as a belt buckle, necklace, or other metal worn
under clothing.
● Donotoverlappadsorputpadsontopof
each other. It may weaken or stop therapy, or
the unit may stop working. Gel pads may also
stick together and cause gel to be removed
when separating.
● Donotsharepadswithanotherperson.This
may cause skin irritation or infection. Pads are

10
intended for one person to use only.
● Donotleavepadsattachedtotheskinafter
treatment.
● Donotbendorfoldbecausethegelmayget
damagedanditwon'tstickorfunctionproperly.
● Toavoiddamagingtheadhesivesurfaceof
the pads, put the pads only on the skin or on
the plastic pad film provided.
● Alwaysplacecleanpadsinaccordancewith
illustrations provided.
● Donotapplyointmentoranysolventto
the pads or to your skin because it will disrupt
the pads from functioning properly. The self-
adhesive pads will adhere to your skin.
● Donotuseitwhenthecolloidattachedto
pads becomes less or dry.

●There is a spasm period after a
cerebrovascularaccident;
●Cognitive impairment, consciousness or
unclearperception;
● Pregnantwomen;
●Patients wearing metal built-in devices such

OPERATING INSTRUCTIONS
BEFORE USE:
1. Do not use this device during charging (fully
charged in 3-4 hours). It is normal that it cannot be
turned on while charging.
2. When the device is in no-output status, it will
automatically shut down if there is no further action
within 5 minutes.
HOW TO USE
1. Clean your skin before use. Use the pads on
clean and flat areas, no sweat and no oil.
2. Attach one pair or two pairs of the electrode
pads to the massager area, such as the shoulder
and leg.
Note: If the stickiness is not good enough after
a period of use, please try to add a few drops of
water on the pads and dry the pads naturally. It can
increase their longevity. Make sure both pads on
the skin do not overlap.
3. Connect a pair of electrode pads to one lead
wire, and the other end of the wire should be
connected to one of the two output ports of the
device. Similarly, the other pair of electrode pads
should be connected to the other output port of the
device through the remaining wire.
