INTRODUCTION TO TENS
What is Pain?
Pain is the body’s warning system. Pain is important because it signals an
unusual condition in the body and alerts us before additional damage or injury
can occur. However, long-lasting, persistent pain, often called chronic pain,
once diagnosed serves no apparent purpose. TENS is developed to help re-
lieve some types of chronic and acute pain.
How does TENS work?
TENS is a method of treating pain that is non-invasive and non-narcotic.
The TENS device sends comfortable pulses 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 you feel by masking the original
pain message sent to the brain.
It is also believed that TENS stimulation helps release endorphins into the
blood stream thereby further reducing pain.
TENS devices are clinically proven useful in pain management for many
patients. By reading this manual and carefully follow the treatment instructions
given to you by your physician/clinician, you will attain the maximum benet
from your TENS device.

INDICATIONS AND CONTRAINDICATIONS
Read the operation manual before using TENS
INDICATIONS
Transcutaneous Electrical Nerve Stimulation (TENS) may be used, with a
physician’s prescription, for the symptomatic relief and management of chronic
(long term) pain.
CONTRAINDICATIONS
●Patients with implanted electronic devices(for example, a pacemaker)
or metallic implants should not undertake TENS treatment without first
consulting a physician.
●Any electrode placement that applies current to the carotid sinus (neck)
region.
●Any electrode placement that causes current to flow trans cerebrally
(through the head).
●The use of TENS whenever pain symptoms are undiagnosed, until etiology
is determined.

2 3
WARNINGS AND PRECAUTION
WARNINGS
●TENS devices must be kept out of reach of children.
●The safety of TENS devices for use during pregnancy or delivery has not
been established.
● TENS is not e󰀨ective for pain of central origin (headaches).
●If TENS treatment becomes ine󰀨ective or unpleasant, stimulation should
be discontinue until reevaluated by a physician.
●Avoid adjusting controls while operating machinery or vehicles.
●Always turn the TENS device OFF before applying or removing electrodes.
●TENS may interfere with electronic monitoring equipment (ECG monitors/
alarms).
●Electrodes should not be placed over the eyes, in the mouth, or internally.
●TENS devices have no curative value.
●TENS is a symptomatic treatment and as such suppresses the sensation if
pain which would otherwise serve as a protective mechanism.
●The patient is an intended operator.
●No servicing or maintenance while the equipment is in use.

4 5
PRECAUTIONS/ADVERSE REACTIONS
●Isolated cases of skin irritations may occur at the site of electrode
placement during long term application.
●Effectiveness is highly dependent upon patient selection by a person
qualied in the management of pain patients.
●Skin irritation and electrode burns are potential adverse reactions.
●The applied part is electrode pad.
●Please dispose it according to the local rule of the disposition of electronic
device/accessory.
● No modication of this equipment is allowed.
●Stimulation connection a PATIENT to a high frequency surgical ME
EQUIPMENT may result in burs at the site o the STIMULATOR electrodes
and possible damage to the STIMULATOR.
●Operation in close proximity (e.g. 1m) to a shortwave or microwave therapy
ME EQUIPMENT may produce instability in the STIMULATOR output.
●Do not apply stimulation across the chest because the introduction of
electrical into the chest may cause rhythm disturbances to the heart.

ABOUT THIS DEVICE
Your TENS device is a battery operated device that includes two controllable
output channels. This TENS device creates electrical impulses whose
amplitude, duration, and modulation can be altered with the controls or
switches. The TENS dial controls are very easy to use and the slide cover
prevents accidental changes in settings.
We recommend that you consult a physician/clinician before using TENS
device.

UNIT CONTROLS
Panel Cover
A cover conceals the controls for Pulse Width, Pulse Rate, Mode Selector and
Modulation Selector. The TENS dial controls are very easy to use and the
slide cover protects accidental changes in settings.
Intensity
The intensity knobs located on the top of the unit affect the strength of the
stimulation and also function as ON/OFF controls.
Mode
The Mode switch is used to select the type of treatment utilized. The three
modes are Burst (B), Continuous (C), and Modulation (M).
Pulse Width
The Pulse Width knob regulates the pulse width for both channels.
Pulse Rate
The Pulse Rate knob regulates the number of pulses per second for both
channels.
Time Control
Treatment Time of TENS can be preset with timer control. This switch has 3
positions: 30, 60 minutes and C (continuous). Push the mode selector until
engaged in position desired.
Resetting the Timer
To resume operation or to reset the timer, simply turn the intensity control OFF
and then ON again.

6 7
Mode Functions
Burst (B) releases individual bursts twice per second, pulse width is adjustable
and the pulse rate is set at 100Hz per second.
Continuous (C) stimulation is delivered continuously at the settings
determined by intensity, rate, and width knobs.
Modulation (M) pulse width decrease from its setting by 60% and maintain the
decreased width for 2 seconds before returning to the original width setting,
which is maintained for 3.5 seconds. The cycle is then repeated. The intensity
and pulse rate are adjustable.
NOTE: Use care when you plug and unplug the wires. Pulling on the lead
wire instead of its insulated connector may cause wire breakage.
CAUTION: Never insert the plug of the lead wire into an AC power supply
socket.

ELECTRODE SELECTION AND CARE
Your physician/clinician should decide which type of electrode is best for your
condition.
Follow application procedures outlined in electrode packaging will provide
instructions for care, maintenance and proper storage of your electrodes.
TIPS FOR SKIN CARE
Good skin care is important for comfortable use of your TENS device.
●Always clean the electrode site with mild soap and water solution, rinse
well and blot dry thoroughly prior to any electrode application.
●Any excess hair should be clipped, not shaved, to ensure good electrode
contact with the skin.
●You may choose to use a skin treatment or preparation that is
recommended by your physician/clinician. Apply, let dry, and apply
electrodes as directed. This will both reduce the chance of skin irritation
and extend the life of your electrodes.
●Avoid excessive stretching of the skin when applying electrodes. This is
best accomplished by applying the electrode and smoothly pressing it in
place from the center outward.
●When removing electrodes, always remove by pulling in the direction of
hair growth.
●It may be helpful to rub skin lotion on electrode placement area when not
wearing electrodes.

CONNECTING THE TENS DEVICE
1. Prepare the skin as previously discussed and according to instructions
provided with your electrodes. Before attaching the electrodes, identify the
area which your clinician has recommended for electrode placement.
2. Connect the lead wires to the electrodes before applying the electrodes to
the skin.
NOTE: Be sure both intensity controls for Channel 1 and 2 are turned to
the “OFF” position.
3. Place the electrodes on the skin as recommended by your physician/
clinician.
4. Insert Lead Wire Connector to TENS device Plug end of lead wire into the
channel output receptacle to be used, pushing plug in as far as it will go.
5. Select Treatment Settings Check and be sure your unit is still set to the
proper settings recommended by your physician/clinician.
6. Adjusting Channel Intensity Control
Locate the intensity control knob at the top of the unit. Turn channel 1 or 2
clockwise. The indicator light will light up as long as the unit is in operation.
Slowly turn the channel control in a clockwise direction until you reach the
intensity recommended by your medical professional. Repeat for the other
channel if both channels are to be used.

Changing the Battery
When the yellow indicator light located on the front of the unit does not remain
lit once the unit is turned on, the battery should be replaced with a new battery.
When the yellow indicator light on the front of the unit does not remain lit once
the unit is turned ON, the battery should be replaced with a newly charged
battery.
1. Remove the panel cover by pressing the top and sliding down until it is
completely removed from the unit this will reveal the battery compartment.
2. Remove the discharged battery from the device.
3. Place new battery in compartment. Note the proper polarity alignment
indicated on the battery and the compartment.
