INTRODUCTION
Thank you for purchasing the Med- it Premier 2 Wireless TENS and Neuromuscular
Stimulator.
It is the most advanced Wireless Stimulator and is manufactured to the highest of medical
standards which fully comply to the Medical Device Directive (M.D.D).
GENERAL DESCRIPTION
The Med- it Premier 2 Wireless TENS/EMS device is a rechargeable battery operated
Stimulator which sends electrical impulses from the remote control to the modules.
The TENS device uses the latest bluetooth technology which allows uninterrupted use of
the TENS regardless of where you may be. After 2 minutes of operating the device, your
remote control will go into sleep mode (saving battery life). By pressing any button on your
remote will reactivate the remote control allowing further adjustment if required.
The electrodes are attached to the modules using snap connectors, which are then placed
over the painful site. This stimulates the nerves causing the pain, which in turn blocks the
pain signals to the brain.
SKIN PATCH TEST
It is recommended that you carry out a patch test before applying your first treatment, To
do this, remove one electrode from the packaging and place on a part of your body which is
both visible and easy to inspect. After 30 minutes, remove the electrode and inspect the
area for any redness or irritations. If no change is noticed, proceed with your first TENS
treatment following the User Guide and Instructions provided. If skin irritation has been
noticed, we recommended the use of sensitive gel electrodes.
FA S
Question: The sensation is not as strong as when I first received my TENS.
Answer: Apply a small amount of water to the gel pad as described on page 11 of this
guide. Each gel pad has a maximum of 10/15 applications before a replacement
gel pad is required.
Question: I need to increase the intensity a little higher each day.
Answer: Applying TENS to the same area each day can dry out your skin. It is important
to wipe the treatment area with warm water before applying your electrodes

IMPORTANT PLEASE READ!
The Med- it Wireless TENS uses high quality medical grade Self-Adhesive Hydro-Gel pads,
which adhere to your skin (please see connecting the self-adhesive electrodes section in
this user manual).
Each time you apply the pad to your skin the Hydro-Gel loses a small amount of moisture.
After the 3rd or 4th application it is important to smear a small amount of water over the
gel pad and wait for approximately one minute for the water to be absorbed into the gel.
The process re-activities the gel pad and increases the adhesive properties. It also helps to
reduce the skin impedance on applications to the skin giving a more pleasant sensation.
SKIN PREPARATION BEFORE APPLYING YOUR
ELECTRODES
It is important that your skin is clean and free from any oils gels or creams before applying
your adhesive pads to the skin.
We recommend however to rub the area to be treated with warm water before applying the
electrodes as this will give the most comfortable stimulation and decrease your skin
resistance.

ELECTRODE INSTRUCTIONS
Turn Stimulator O before applying or removing electrodes
Appli ation
1. Skin site must be very clean and dry. Dirty, flaky or oily skin will prevent electrodes from adhering to
the skin. If necessary, trim excess hair with scissors. If skin is oily wipe down with an alcohol or
electrode skin prep prior to application. Be sure to wash hands before handling electrodes.
2. Remove electrodes from bag and reseal bag to protect remaining electrodes.
3. Grasping a tiny edge of the electrode, peel and remove electrode from the protective plastic liner.
Save liner for electrode storage.
4. Place electrode onto skin treatment site (as recommended by your clinician) by firmly applying from
the centre of the electrode to the outer edges. Adhesion improves when electrodes reach skin
temperature.
5. If gel appears oversaturated with excessive moisture or perspiration, allow the electrode to air-dry
in a refrigerator with the gel side facing up until the gel regains its tack. If the gel appears dry, try
adding a few drops of water to the gel and allow to rest in a dust-free environment until the gel
regains its tack.
Removal and storage
1. Lift a corner of the electrode and slowly peel the electrode off the skin, touching the adhesive gel as
little as possible.
2. Place the electrodes back onto the saved protective plastic liner.
3. While grasping the electrodes connector with one hand, use the other hand to gently twist and
disconnect the lead wire pin from the electrode connector. .
4. Return the electrodes back into the storage bag and reseal tightly to prevent dry-out.
5. Store at room or cool temperature and keep out of direct sunlight.
6. The life of the electrode varies depending on skin conditions, amount of use, storage and climate.
Electrode life may be extended by carefully following the application, removal, and storage
instructions.
Caution
1. DO NOT place electrodes on broken skin. If skin irritation develops discontinue use. Consult
physician. Replace electrodes when they do not adhere or when treatment becomes uncomfortable.
2. DO NOT use unit while driving or operating machinery
3. DO NOT wear electrodes when showering, bathing or swimming
4. DO NOT apply electrodes across the head or across the heart or on the front of your neck.
5. Keep electrodes separated during treatment
6. Using stimulation electrodes that are small or incorrectly applied could result in discomfort or skin
burns.

WARNINGS
1. The long term effects of chronic electrical stimulation are unknown.
2. Stimulation should not be applied over the carotid sinus nerves, particularly in patients with
a known sensitivity to the carotid sinus reflex.
3. Stimulation should not be applied over the neck or mouth. Severe spasm of the laryngeal
and pharyngeal muscles may occur and the contractions may be strong enough to close the
airway or cause difficulty in breathing.
4. Stimulation should not be applied transthoracically in that the introduction of electrical
current into the heart may cause cardiac arrhythmias.
5. Stimulation should not be applied transcerebrally
6. Stimulation should not be applied over swollen, infected, inflamed areas or skin eruptions,
eg, phlebitis, thrombophlebitis, varicose veins etc.
7. Stimulation should not be applied over or in proximity to cancerous lesions.
Contraindi ation
Electrical stimulators should not be used on patients with cardiac demand pacemakers.
Adverse Rea tions
On rare occasions skin irritation and burns beneath the electrodes have been reported with the
use of electrical stimulators. If irritation occurs, discontinue use and consult your Healthcare
Professional.
CAUTIONS
1. Safety of powered muscle stimulators for use during pregnancy has not been established.
2. Caution should be used for patients with suspected or diagnosed heart problems.
3. Caution should be used in the presence of the following:
a. When there is a tendency to haemorrhage following acute trauma or fracture;
b. ollowing recent surgical procedures when muscle contraction may disrupt the healing
process;
c. Over the menstruating or pregnant uterus; and
d. Over areas of the skin which lack normal sensation.
4. Some patients may experience skin irritation or hypersensitivity due to electrical stimulation
or electrical conductive medium. Using an alternate conductive medium, or alternate
electrode placement can usually reduce the irritation.

INTRODUCTION TO TENS
What is TENS?
Transcutaneous electrical nerve stimulation is a pain control treatment. It is often called
TENS for short.
A TENS unit is a portable, pocket-sized, battery-powered device.
The TENS unit uses mild, safe electrical signals to help control pain and delivers the
electrical signal to the body through self-adhesive conductive electrodes.
How does TENS work?
The most common TENS programmes use
high-frequency stimulation, which is the first choice for both acute and chronic pain.
High-frequency stimulation sends impulses to the nervous system’s own pain-inhibiting
mechanisms, which block the pain.You can use it as often and as long as you like, but each
treatment should last at least 1 hour.
Another type of TENS is low-frequency stimulation. Low-frequency TENS treatment can
alleviate pain by stimulating muscles to release the body’s own morphine-like substances,
called endorphins.

INTRODUCTION TO TENS
During the TENS treatment
If your muscles start to twitch, this may mean that the TENS signals are too strong or too
fast. If you cannot feel any tingling at all, this may mean that the signal is too weak or too
slow.
The electrodes should be removed at least once a day if the TENS treatment is used around
the clock. The skin under the electrodes must be checked to see if it is red or tender. The
skin should also be cleaned and dried while the electrodes are off. Apply lotion to your skin
where the electrodes were placed. The electrodes should be applied to a different area for
each new treatment. This will help prevent the skin from becoming red or sore.
TENS an be used for
TENS can be used to treat most types of pain where the cause has been determined
including:
• Arthritis
• Back Pain Post Herpetic
• Bruising Neuralgia

WHICH PROGRAMME SHOULD I USE?
We always recommend you start with programme 3, as already mentioned in your step-by-
step guide. The Med- it 2 Premier Wireless TENS has 9 programmes P1 to P9, Each
programme has been shown to reduce and block pain in a wide range of conditions. It is
very difficult to know which programme is best for you. It is therefore recommended that
over a period of time you try all 9 programmes. To help get you started, we have included
some common conditions with suggested electrode placements including treatment times
and recommended programmes you may wish to try.
HOW HIGH SHOULD I TURN THE INTENSITY?
Everybody reacts differently to TENS Stimulation so it is important that you increase the
intensity (sensation feeling) to the correct level.
Increase the intensity to a sensation which is comfortable and always perceptible; never
turn up to a level which is strong and uncomfortable.
You may use TENS if required for long periods of time to combat long term chronic pain;
however, please remember to place the electrodes in slightly different areas around the
painful site, as this will help reduce skin irritation.
The most up to date research in TENS treatment times indicates that a minimum of 1 hour
to 11/2hours is required for effective pain relief. Your TENS may be used for much longer
periods and you may find treatment times of 3 to 4 hours may work best for you.
Please remember that the intensity level is always kept at a pleasant sensation, never
increase the intensity to uncomfortable levels as this can possibly have a detrimental effect
on your results.

HELPFUL TIPS FOR SUCCESSFUL
TENS TREATMENT
Once you have familiarised yourself with the controls and features of your TENS device, it
is important to place the TENS electrodes in a position which gives the most pain relief.
This may take 3 or 4 attempts to find the most suitable position for maximum pain relief.
If you are using one module, place the electrode directly onto the painful area.
The alternative method is to use two modules surrounding the painful area. See examples
below.
The complete area between the electrodes will now be treated when positioning the
electrodes as shown.
One Module wo Modules
