Chapter 1: INTRODUCTION
EXPLANATION OF PAIN
Pain is a warning system and the body’s methode of telling us that
something is wrong. Pain is important; without it abnormal conditions
may go undetected, causing damage or injury to vital parts of our bodies.
Even though pain is a necessary warning signal of trauma or malfunction
in the body, nature may have gone too far in its design. Aside from its
value in diagnosis, long-lasting persistant pain serves no useful purpose.
Pain does not begin until coded message travels to the brain where it is
decoded, analyzed, and then reacted to. The pain message travels from
the injured area along the small nerves leading to the spinal cord. Here
the message is switched to different nerves that travel up the spinal cord
to the brain. The pain message is then interpreted, referred back and the
pain is felt.
EXPLANATION OF TENS
Transcutaneous Electrical Nerve Stimulation is a non- invasive, 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 cure any physiological problem; it only helps control the pain. 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.
HOW TENS WORKS
There is nothing “magic” about Transcutaneous Electrical Nerve
Stimulation (TENS). TENS is intended to be used to relieve pain. 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. You may discuss this with your physician or
therapist.
IMPORTANT SAFETY INFORMATION!
Read instructions manual before operation. Be sure to comply with all
“CAUTIONS” and “WARNINGS” in the manual. Failure to follow
instructions can cause harm to user or device.
INDICATIONS FOR USE
This device is designed to be used for temporary relief of pain associat-
ed with sore and aching muscles in the shoulder, waist, back, upper
extremities (arm) and lower extremities (leg) due to strain from exercise
or normal household work.
Chapter 2: CAUTIONS
1. Federal law allows over the counter (no prescription) sales of
this device.
Chapter 3: WARNINGS
1. DO NOT use this device for indiagnosed pain syndromes until
consulting a physician.
2. Patients with an implanted electronic device, such as cardiac
pacemaker, implanted defibrillator, or any other metallic or
electronic device should not undergo TENS treatment without first
consulting a doctor.
3. Patients with heart disease, epilepsy, cancer or any other health
condition should not undergo TENS treatment without first
consulting a physician.
4. Stimulation delivered by this device may be sufficient to cause
electrocution. Electrical current of this magnitude must not flow
through the thorax or across the chest because it may cause a
cardiac arrhythmia.
5. DO NOT place electrodes on the front of the throat as spasm of the
Laryngeal and Pharyngeal muscle may occur. Stimulation over the
carotid sinus (neck region) may close the airways, make breathing
diffucult, and may have adverse effects on the heart rhythm or
blood pressure.
6. DO NOT place electrodes on your head or at any sites that may
cause the electrical current to flow trans-cerebrally (through
the head).
7. This device should not be used while driving, operating machinery,
close to water, or during any activity in which involuntary muscle
contractions may put the user at undue risk of injury.
8. Turn the TENS off before applying or removing electrodes.

9. Isolated cases of skin irritation may occur at the site of electrode
placement following long term application. If this occurs,
discontinue use and consult your physician.
10. If TENS therapy becomes ineffective or unpleasant, stimulation
should be discontinued until its use is re-evaluated by a physician.
11. Keep this device out of the reach of children.
12. InTENSity 7 devices have no AP/APG protection. Do not use it
in the presence of explosive atmosphere and flammable mixture.
13. It is recommended not to exceed a current density of
2 mA /cm2,otherwise skin irritations or burns can occur.
We recommend that:
• Please use specific size electrodes provided by manufacturer
to avoid skin irritations or burns.
• For smaller electrodes, the maximum current setting of the
waveform should be appropriately reduced.
• Please place the electrodes carefully, ensure that the entire
surface of the electrode has good contact with the skin.
14. TENS devices have no curative value.
15. TENS is a symptomatic treatment, and as such suppresses the
sensation of pain, which would otherwise serve as a protective
mechanism.
16. TENS is not effective for pain of central origin (This includes
headache).
17. Electronic monitoring equipment (such as ECG monitors and ECG
alarms) may not operate properly when TENS stimulation is in use.
18. Caution should be used in applying TENS to patients suspected of
having heart disease. Further clinical data is needed to show there
are no adverse results.
19. Electrodes should not be placed over the eyes, in the mouth,
from the chest and the upper back or crossing over the heart,
or internally.
20. DO NOT use while sleeping.
21. DO NOT use during pregnancy unless directed by your physician.
22. Simultaneous connection of a PATIENT to a high frequency
surgical device may result in burns at the site of the STIMULATOR
electrodes and possible damage to the STIMULATOR.
23. Operation in close proximity to a shortwave or microwave therapy
device may produce instability in the STIMULATOR output.
24. DO NOT insert the plug of the patient lead wire into any AC power
supply outlet.
25. NEVER apply electrodes over irritated or broken skin.
26. DO NOT use TENS over the carotid sinus (neck) region.
27. TENS devices can affect the operation of demand type cardiac
pacemakers.
28. DO NOT use TENS device if you have heart disease without
consulting your physician.
29. DO NOT stimulate on the site that may cause current to flow
transcerebrally (through the head).
30. DO NOT apply TENS for underdiagnosed pain syndromes
until etiology is established.
31. DO NOT insert the plug of the patient lead wire into any AC power
supply socket.
Chapter 4: CONTRAINDICATIONS
1. DO NOT use TENS over the carotid sinus (neck) region.
2. TENS devices can affect the operation of demand type cardiac
pacemakers.
3. DO NOT use TENS device if you have heart disease without
consulting your physician.
4. DO NOT stimulate on the site that may cause current to flow
transcerebrally (through the head).
5. DO NOT apply TENS for underdiagnosed pain syndromes until
etiology is established.
Chapter 5: ADVERSE REACTIONS
Skin irritation and electrode burns are potential adverse reactions.
If skin irritation occurs, discontinue use and consult your physician.
Chapter 6: GENERAL DESCRIPTION
The InTENSity 7 is a battery operated pulse generator that sends
electrical impulses through electrodes to the body and reaches nerves
causing pain. The device is provided with two controllable output
channels, each independent of each other. An electrode pair can be
connected to each output channel.
The electronics of the InTENSity 7 create electrical impulses whose
intensity, duration, number per second and modulation may be altered
with the controls / switches. Press buttons are very easy to use and
the large liquid crystal display showing the exact mode and values of
parameters are very convenient for patients.

InTENSity 7

Adjustable, 0-100 mA at 500 ohm

The technical specification details of InTENSity 7 are as follows:

not try to replace the other parts of the device.

InTENSity 7

Replacement electrodes should be approved for over-the-counter use.
Follow application procedures outlined in the electrode packaging to
maintain optimal stimulation and to prevent skin irritation.
Wipe the area with skin preparation wipes. Let the area dry.
NEVER apply electrodes over irritated or broken skin.
Excess hair may be clipped with scissors; DO NOT shave
stimulation area
Apply electrodes as directed.
you current
The placement of electrodes can be one of the most important
parameters in achieving success with TENS therapy. Placing the
electrodes at least 2" apart but no more than 6" apart will help
with successful therapy.

local
1. DO NOT attempt to charge any other types of batteries in
your charger, other than the rechargeable batteries made for
your charger. Other types of batteries may leak or burst.
2. DO NOT incinerate the rechargeable battery as it may
explode!
