1 Introduction
Congratulations on your purchase of the MEND ProfessionalTM (IS02PROs)
device. The MEND ProfessionalTM is the most advanced two channel
programmable transcutaneous electrical nerve stimulator or "TENS" device
currently available. MEND Technology is a leading distributor of state-of-the-
art medical devices.
The MEND ProfessionalTM is a high-end precision medical device used for the
relief of pain. This device generates low intensity current pulses at microampere
levels and frequency of pulses. This unit can hold multiple therapy protocols.
Each protocol includes multiple frequency pairs. Health practitioners can
program each frequency pairs with a variety of parameters including current
intensity, frequencies, time, modulated wave period, wave slope, and polarity.
The microampere level current is applied by electrodes.
The MEND ProfessionalTM is a small, portable device that is designed for use in
a doctor's office, clinic orhospital as well as self-administered treatment at home
under a practitioner’s supervision.
Please read this entire manual thoroughly before using it.

1.1 Indications
The MEND ProfessionalTM is intended for the symptomatic relief of chronic
intractable pain. The degree of efficiency will vary with patient selection.
1.2 Warnings and Contraindications
•Microcurrent stimulation should not be used on patients whose pain
syndromes are not diagnosed and etiology is not established. If another
electrode is used as a dispersive electrode, placement of the dispersive
electrode should ensure transthoracic stimulation is not possible.
• Safety of microcurrent stimulation has not been established during
pregnancy or birth. Microcurrent stimulation is not effective for pain of
central origin including headache.
• Microcurrent stimulation should be used only under the continued
supervision of a licensed physician. Microcurrent stimulation has no
curative value. Microcurrent stimulation is a symptomatic treatment and
as such suppresses the sensation of pain which would otherwise serve as
a protective mechanism.
• The stimulation and electrodes should not be applied across or through
the head, directly on the eyes, covering the mouth, on the front of the
neck, especially over the carotid sinus (upper side of neck), or from
electrodes placed on the chest and the upper back or crossing over the
heart. Application of electrodes near the thorax may increase the risk of
cardiac fibrillation.
• Don’t use microcurrent stimulation on patients who have a demand type
pacemaker. A patient with an implanted electronic device (for example a
cardiac pacemaker) should not be subjected to stimulation unless
specialist medical opinion has first been obtained.
• Do not allow children to use or handle this device. Keep the device and
lead wires away from children when not in use. Strangulation could
result from baby or child entanglement in the wire leads.
• Do not operate vehicles or potentially dangerous machinery during
periods of stimulation.

7
•Electronic monitoring equipment such as ECG monitors and ECG
alarms may not operate properly when Inspirstar IS02 PMS is in use.
•Simultaneous connection of a patient to a high frequency surgical
medical equipment may result in burns at the site of the IS02 PMS
electrodes and possible damage to the IS02 PMS.
•Operation in close proximity (e.g. 1 m) to a shortwave or microwave
therapy medical equipment may produce instability in the IS02 PMS
output.
1.3 Adverse Effects
Please consult your doctor about possible adverse effects which may arise
from the therapy protocols your doctor is using. A common issue is about
skin reaction at the electrode sites. Skin irritation and electrode burns are
potential adverse reactions. Cleaning and hydrating the skin are usually valid
methods to reduce the skin irritation or electrode burns. If gloves or cloth or
garment are used as electrodes, these gloves or cloth or garment should be
wet or damp. If electrode pads are used, sometimes conductive gel on pads
can be helpful to increase the conductivity and reduce the skin reaction.
1.4 Precautions and Safety Notices
Isolated cases of skin irritation may occur at the site of conductive materials
following long-term application. The effectiveness of the MEND ProfessionalTM
device is highly dependent upon patient selection by a practitioner qualified in the
management of pain. Electrode placement and stimulation settings should be based
on the guidance of the prescribing practitioner. Patients should not use the device
while under the influence of alcohol, controlled substances or narcotic drugs,
directly on the eyeball, or over a vessel that may contain a blood clot.
Caution should be used for persons with suspected or diagnosed epilepsy.
CAUTION
Federal Law (USA) restricts this device to sale by or
on the order of a licensed health care practitioner.

8
•The device is to be applied with electrodes to the skin of the human
body.
•The device has micro amperage current output. The plugs must be inserted
completely into the jacks. The patient may experience prickling sensation
if the skin contact is too dry. Moisture the skin before use.
•Only use the recommended accessories. It can be unsafe to use
accessories not in the instructions for use.
•Use alkaline batteries only. It cannot be connected to external power
source. Any attempt to do so would cause damage of the device and
possibly cause harm to the patient.
•Water into the device could affect the safety and performance. Do not
use the device when the device has got water inside. Do not let water
flowing on the surface of the device. Do not immerse the device into
water. Do not use the device close to flammable mixtures or
concentrated flammable fumes such as gasoline.
• The device can only be opened and repaired by the manufacturer or
licensed service personnel. Do not modify the device as it can be unsafe.
• The device is for indoor use where a patient would comfortably stay.
Consult your physician for use in unusual environment conditions e.g.
strong magnetic fields or electromagnetic fields, external electrical
influences, electrostatic discharge. Do not exposure the device in a high
dust environment for long period of time.
