Note: The electrode pads need to be applied directly to the skin before the intensity increase buttons will operate. If the perfect TENS detects the unit is not properly connected to you (for example if the electrode pads or leads come loose) then the unit switches the intensity to zero. This safety feature prevents any unpleasant changes in output.

HOW “TENS” WORKS

T.E.N.S. stands for Transcutaneous Electrical Nerve Stimulation. T.E.N.S. stimulates your body’s own natural defences against pain, namely the release of endorphins. TENS is totally safe and has been used successfully by thousands of pain sufferers. TENS sends a gentle stimulation through the skin which works in TWO ways: Pain Gate It stimulates the sensory nerves, which carry touch and temperature signals. These nerves go to the same connections in the spine as the nerves carrying pain. A strong sensory signal will block the pain signal travelling up the spine to the brain. This is known as closing the “Pain Gate” and takes effect quite quickly after the unit is switched on.
When the gate is open, pain messages get through to the brain and we feel pain. When the gate is closed, these pain messages are blocked and we do not feel pain.

• Evidence suggests that TENS similarly produce pain relief to ‘rubbing the pain better’. The pain gate can be closed by activation of mechanoreceptors through ‘rubbing the skin’.
• Scientifically, the pain gate works by releasing chemicals in the synapse at the spinal level that inhibit the transmission of pain signals.

Endorphin Release
At low frequency settings, and slightly stronger outputs, TENS drives the motor nerves to produce a small repetitive muscle contraction. This is seen by the brain as exercise, and this promotes the release of endorphins – your body’s own natural pain killer. The relief builds up and normally takes about 40 minutes to reach a maximum level which can last for hours after the machine is switched off.
By using TENS, you can expect to achieve a significant reduction in pain – if not complete relief from pain.

• TENS is effective for pain from a very wide range of causes.
• TENS machines can be used to help reduce pain from problems in muscles, joints and nerves.
• It can be also used for people with musculoskeletal pain such as long-term (chronic) back pain or knee joint arthritis. They are also often used for pain relief in the early stages of labour (see perfect mamaTENS), particularly whilst a pregnant woman remains at home.
• TENS may also be used to treat many types of pain, such as period pain and endometriosis (see Ova+), cystitis, sports injuries, fibromyalgia and neuralgia, plantar fasciitis, post-operative pain, TMJ disorder, diabetic neuropathy, osteoarthritis and sometimes non-painful conditions such as travel sickness.
• You can use low-frequency (<10 Hz) programmes on acupuncture points, to achieve similar effects to acupuncture.
• With neurogenic pain (caused by inflamed nerves) such as neuralgia, TENS may start by increasing the pain. We recommend that you only use TENS for these conditions under medical supervision.
• You can safely use TENS as long as it gives you pain relief. The effect may wear off after a few hours (this is called “accommodation”). If this happens, take a break of an hour or so before trying again. If you use settings that cause muscle movement for more than 40 minutes, you may experience aching muscles a few hours later.

CONTRAINDICATIONS, WARNINGS & CAUTIONS

In this manual

• Contraindication is used when a device should not be used because the risk of use outweighs any foreseeable benefits and may result in serious injury or death.
• Warning is used when failure to follow the instructions may result in serious injury or death.
• Caution is used when failure to follow the instructions may result in a minor or moderate injury or damage to the device or other property.
• Notes are used to provide clarification or recommendations.

CONTRAINDICATIONS

• Do NOT use if you have a pacemaker (or if you have a heart rhythm problem) or with any electronic medical devices. Using this unit with electronic medical devices may cause erroneous operation of the device. Stimulation in the direct vicinity of an implanted device may affect some models.
• Do NOT use during the first three months of pregnancy. It is not known whether TENS may affect foetal development.
• Do NOT use on the abdomen in the later stages of pregnancy. Stop using it immediately if you experience unexpected contractions.

WARNINGS
Do NOT use when driving, operating machinery, or similar actions needing muscular control. Loose electrode pads, damaged leads, or sudden changes in contact may cause brief involuntary muscle movements.

• Do NOT use to mask or relieve undiagnosed pain. This may delay the diagnosis of a progressive condition.
• Do NOT use if you have, in the area being treated: active or suspected cancer or undiagnosed pain with a history of cancer. Stimulation directly through a confirmed or suspected malignancy should be avoided as it may stimulate growth and promote the spread of cancer cells.
• Do NOT use electrodes on the front of the neck. Stimulation on the front of the neck can affect your heart rate or cause contraction of the throat.
• Do NOT use electrodes across the chest. Very strong stimulation across the chest may cause an extra heartbeat and/or rhythm disturbances to your heart, which could be lethal.
• Do NOT use Perfect TENS while simultaneously connected to high-frequency surgical equipment as it may result in burns at the site of stimulator electrodes and possible damage to the stimulator.
• Do NOT use Perfect TENS close (e.g. 1 m) to a shortwave or microwave as this may produce instability in the stimulator output.
• Do NOT use electrodes near the thorax as this may increase the risk of cardiac fibrillation.

CAUTIONS

• Caution should be used if you have a bleeding disorder as stimulation may increase blood flow to the stimulated region.
• Caution should be used if you have suspected or diagnosed epilepsy as electrical stimulation may affect seizure threshold.
• Caution should be observed when using the device at the same time as being connected to monitoring equipment with body-worn electrode pads. It may interfere with the signals being monitored.
• Caution should be used following recent surgical procedures. Stimulation may disrupt the healing process.

Note: There are no known side effect to TENS use and long-term TENS use is not harmful.

INFORMATION ABOUT THE PROGRAM SETTINGS

Each programme has its own combination of Frequency and Pulse Width settings which allow for different sensations through the electrode pads and suppress pain in different ways.

• Frequency (measured in Hz – pulses per second)
  PAIN GATE: A high frequency of 110 Hz is good at blocking pain signals.
  ENDORPHINE RELEASE: A low frequency of 4 or 10 Hz allows for the release of endorphins, the body’s natural morphine-like substances.

• Pulse Width (measured in μs – millionths of a second)

• The perfect TENS unit has pulse widths of 50 to 250 μs. Generally speaking, the higher the pulse width, the more “aggressive” the stimulation feels, and eventually, if the pulse width is set high enough, it will usually elicit a muscle contraction, which is typically not the desired result with a TENS unit. However, if the pulse width is too low, the patient may not perceive the stimulation. Pulse Rate is important because different frequency settings target different nerve groups and the setting will determine if the “Gate Theory” or “Endorphin Theory” of TENS will be used.

Constant and Burst Modes
Constant mode is when the sensation is continuous whereas Burst mode is when the sensation, as its name implies, is one of on and off. Constant mode is often used for acute pain via Pain Gate Effect whereas Burst mode is useful in chronic pain relief. Burst gives a combination of Pain Gate and Endorphin Release, but the squeezing feeling may not be as comfortable. The sensation in Burst is more of a ‘grabbing’, ‘clawing’ type and usually more by way of muscle twitching than with the high or low-frequency modes. The stimulation intensity will need to be relatively high. In Constant mode, the sensation is continuous and is more of a tingling pins and needles type.

Modulation Modes
Modulation is when either the frequency or pulse width sweeps across a range of settings. In modulation mode, the machine delivers a less regular pattern of TENS stimulation in an attempt to reduce or minimise the accommodation effects of regular, patterned stimulation. This is potentially most useful for patients who use TENS for several hours a day if for no other reason than accommodation occurs at a slower rate and therefore less intensity adjustment may be required. See programmes F and G.

HAN Stimulation
Invented by Professor Han, it is an alternating mode or shifting between high and low frequencies; stimulation works at a high frequency and a relatively low pulse width; and a low frequency and a relatively high pulse width. This is thought to produce a better analgesic effect and could be used to relieve both acute and chronic pain.

• F – The user increases the strength to the desired level in the first 7 seconds. The strength drops down 90% for 6 seconds and then gradually starts increasing again to the original setting for 6 seconds.
• G – The frequency starts at 2 Hz and after every 3 minutes shifts to the next frequency setting. After 21 minutes, it returns back to 2 Hz and starts the cycle over again.

Note: Specifications are nominal and subject to variation from the listed values.

PRESET PROGRAMMES

• There is not one programme for a particular condition, and the best choice varies from one person to another, even if they have the same type of pain.
• Each user needs to select both the programme and the positioning of the electrode pads that is best for them. You may need to try a few positions/programmes before finding the one that suits you.
• If you are using TENS for the first time, it is recommended that you start with programme A, which gives the gentlest stimulation.
• The perfect TENS has 8 preset pain relief programmes.
• P=Pain Gate. Gives relief when being used. Wears off after a few hours.
• E= Endorphin Release. Builds up over 40 mins. Lasts several hours after use.

Programme A
P – This is the gentlest programme. It is advisable to use for your first trial of TENS while you get used to the feeling which offers a tingling/pins and needles sensation. Reduced pulse width is ideal for treating nerve-rich areas (tension-type headache, facial pain, neck pain, post-herpetic neuralgia, migraine).
Programme B
E – This low frequency is also known as Acupuncture-Like. Use on acupuncture points. Pulsing or tapping sensation associated with muscle contractions. It is suitable to be used for chronic pains such as back pain & arthritis, but not for injured muscles.

Programme C
P + E – This programme combines P and E and is thought to be the most effective for radiating pain in arms and legs and deep muscular pain (Osteoarthritic pain in the knee, Sciatica central pain).
This programme uses high-frequency in low-frequency bursts. Some people find the changes in stimulation uncomfortable.
Programme D
E – This programme provides soothing/relaxing effects and is ideal for the treatment of nausea, travel and morning sickness; most successful with placing the electrode pads over the wrist (acupuncture point C6). See the instructions enclosed with the electrode pads.
Programme E
P – Stronger, more penetrating version of programme A and a stronger feel. Could be used everywhere except very sensitive areas.
Programme F
P – This program continuously modulates the pulse width and gives a pleasant slow relaxing massage sensation. The continuous change helps prevent accommodation from occurring.
Programme G
P – This programme constantly varies the sensation, and is ideal for treating chronic pain over a long period (for example 5+ hours). Neck, shoulder, Elbow pain, Rheumatic pain, Lumbago, Hip pain, Osteoarthritic pain in the knee.
Programme H
P + E – This programme alternates between low and high frequency every 3 seconds and gives 3 seconds of tapping, followed by 3 seconds of tingling sensation. The effective pain relief is provided by a combination of P and E. Some people find the changes in stimulation uncomfortable.

MANUAL PROGRAMME

Manual Programme M:
Surprisingly little research has been done on the importance of frequency.
Professor Han did research that showed that P increased as the frequency increased – but only tested up to 100 Hz.
And that E decreases as the frequency increases.
So, E is less effective when the frequency is >10 Hz and P is less effective when the frequency is <80 Hz. Most clinical research on P has been done at 80 Hz or 100 Hz.
Many professional users believe that the response to TENS varies between individuals and that you can get the best response by choosing the frequency that suits your nervous system the best. They suggest that you start at 80 Hz or 110 Hz, then try different frequencies until you find one that gives you better pain relief.

• Press the P key until you reach programme M.

• Press the T key. The Hz symbol will flash next to the number at the bottom centre of the screen.

• Press CH1+ or CH1- to adjust the setting. You can select a frequency from 2 to 150 Hz.

• Press the T key again to save your change and advance to the next setting μs. You can select a pulse width from 50 to 250 μs.

• Press the T key to select C or B.

• C = Constant B = Burst

• Finally, you can select the Treatment Timer. Continuous, 10, 20, 30, 40 or 60 minutes.

• Press T once more to return to start using.

See section 6 for more information on the choice of settings.

PROGRAMME USAGE
TENS can be used for as long as it is necessary. Continuous treatment is fine, but the electrode pads should be repositioned regularly (at least every 12 hours) to allow the skin to be exposed to the air.
The Endorphin Release programmes work better when the strength is high enough to cause small muscle contractions. Best results are achieved with a session duration between 20 and 40 minutes. Longer use may cause muscle ache.

ELECTRODE PADS

PAD POSITIONING
The electrode pads must always be used in pairs (two electrode pads on each channel), so that the signal can flow in a circuit.

• TENS works one vertebra at a time. You need to stimulate the sensory nerves that enter the spine at the same level as the nerve carrying your pain. Since you don’t know exactly where your nerves are, the easiest way is to apply the electrode pads around/near the source of the pain.
• TENS activates the nerves best if it travels along the nerve rather than across it. So place one pad further from the spine than the source of the pain, and one closer.
• The nerves wrap around the limbs and torso, so you may have to try a few positions before you get the best effect.
• If the pain is in, or close to, your spine you can place one pad either side of the spine.
• You may feel more sensation in one pad than the other. This is normal – it depends on where the electrode pads are in relation to your nerves.

For areas that are difficult to reach, why not ask a friend to help you attach the electrode pads?

Always check that the unit is OFF before attaching or removing electrode pads.
Perfect TENS resets strength to zero if the pad or lead is disconnected from your body. This is to prevent sudden changes in sensation when the pad is re- connected.
Note: See examples of positioning in the instructions enclosed with your electrode pads.

PAD ADVICE

• The electrode pads supplied are reusable but for single-patient use. The adhesive is a peelable hydrogel (water-based).
• In order to obtain the best conductivity through the electrode pads always ensure that they are in good condition and tacky.
• Before use make sure your skin is clean and dry.
• Peel the electrode pads from their protective plastic shield by holding and lifting one corner of the pad and pulling. Do not pull on the pigtail wire of the pad.
• After use always replace the electrode pads on the plastic liner and replace them in the re-sealable plastic bag.
• If the electrode pads dry out, then it is best to buy a replacement pack. In an emergency, it may be possible to restore some of the tackiness of the pad by adding a tiny drop of water on each pad and spreading around. If too much water is added, the electrode pad will become too soft. If that happens then it is suggested to try and re-establish some adhesiveness, to place them sticky side up in a refrigerator for a few hours.
• In very hot weather the gel on the electrode pads may become soft. In such cases place them, still on their plastic liners and in their pouch into a fridge until they return to their normal condition.
• The electrode pads provided are latex-free.
• Replace the electrode pads when they lose their stickiness.
• Poor connection may cause discomfort and skin irritation.
• Storage life of an unopened pack of electrode pads is 2 years. This may be affected by very high temperatures or very low humidity.

To turn the unit OFF, press the ON/OFF button on the top of the unit and hold for 3 to 5 seconds until the display stops
The unit will turn OFF automatically:

• When the Timer reaches zero,
• If it is left at zero strength for more than 5 minutes.

The unit will start with the programme you used last.
At first use, or after changing batteries, the display shows that the unit is automatically set in Programme A at zero strength.

Note: Always check unit is OFF before applying or removing electrode pads.
The backlight will turn off 10 seconds after the last button press.
On the front of the unit there are six buttons:

STRENGTH CONTROLS
The buttons marked CH1+, CH1-, CH2+, CH2- are the strength controls.

• To increase strength in steps of 1 mA, press and release the top part of the two-channel buttons, marked CH1+ and CH2+.
• The strength levels are shown on the LCD.
• The strength control buttons will not operate until the unit is properly connected to you. Perfect TENS detects a disconnection and automatically returns the strength to zero.
• The unit has 60 levels of strength. If you hold down the button for 3 to 5 seconds, the strength will start scrolling.
• You may feel nothing over the first few presses. Continue pressing until the sensation is strong but comfortable. Further increases during use may be necessary if your body becomes used to the sensation.
• To decrease the strength, press and release the lower part of the buttons marked CH1- and CH2-.
• The yellow LED on the output socket indicates that there is an active output. The display will remain on for 5 seconds after the plug is removed.

PROGRAMME CONTROL

• The button marked P is the programme control. The perfect TENS has eight different, specially developed programmes lettered A to H, plus a manual programme M. When the unit is first switched on it automatically enters programme A.
• Each time you press and release the P button, the programme changes and the letter is shown on the LCD.

Each time you change the programme, the strength level reverts back to zero. This is a safety feature to alleviate any sudden feeling of a surge, as each programme gives a different sensation.

TREATMENT TIMER

• The button marked T can be used to set the session duration and to select manual parameters for adjustment.
• When you switch the unit on, it is automatically set at Continuous, (displayed as C) in all programmes but B, C & H, which means that the unit will continue functioning until you switch it off.
• When you press the T button, the clock symbol will flash.
• You can set session times of 10, 20, 30, 40 or 60 minutes with the CH1+ and CH1- buttons.
• Press T again to save your selection.
• The LCD shows the session duration next to the clock symbol. The unit automatically counts down the minutes set and switches off when it reaches 0.

LOW BATTERY

• An empty battery symbol will show when you need to change the batteries. The unit will shut down about 2 minutes after this.

KEYPAD LOCK

• If you do not press any keys for 30 seconds, the keypad will lock so that only the keys marked CH1- or CH2- will work. This is to avoid accidental changes in the setting.
• To unlock, press either CH1- or CH2- keys.

OPEN CIRCUIT CUTOUT
If the perfect TENS is not correctly connected to your body, the strength in the channel that is not properly connected will automatically reset to zero. This is to prevent sudden changes if a broken connection is re-made.

• Attaching the electrode pads to the lead wire.

• Push the pin ends firmly into the pigtail ends of the electrode pads.

• The lead wires may be damaged by rough handling and should be treated with care.

Lead wire colour coding
The ends of the lead wires are coloured white or red. This coding is provided for some professional uses. For most purposes, the orientation makes no difference, and you can ignore this colour coding.

PREPARING FOR SESSION

1. Before use make sure your skin is clean and dry.
2. Place the electrode pads on the skin, see section 8.
3. You can use your TENS for several hours, you can attach the unit to your belt using the belt clip or hang it around your neck using a neck cord (not included). For safety, use thread or wool that will snap easily if the unit snags on something.
4. You can safely lean on the electrode pads. The sensation might change.

Warning: Ensure the perfect TENS is switched OFF before applying the electrode pads on the skin.

TREATMENT SESSION

1. Press and hold the ON button on the control unit for 3 to 5 seconds to switch the control unit on.
   When switched on for the first time, the perfect TENS will automatically select programme A. Next time, it will automatically select the programme you were using the last time it was switched off.

2. You can select from the 8 preset programmes or the manual programme. Details in section 7 will help you identify the best programme to suit you.

3. With the required programme selected, you can adjust the intensity of the stimulation with the buttons CH1-, CH1+, CH2- and CH2+ until you reach a comfortable level. The LCD shows the strength of intensity used for each channel.

Note: If the sensation becomes uncomfortable, reduce the intensity.

AFTER YOUR TREATMENT SESSION

When the timer reaches 0, your treatment session is complete and the unit turns off.

1. Check that the control unit is OFF. If it is not, hold down the OFF button to switch off then remove the electrode pads from your skin by holding the pad itself and gently pulling. Be careful not to pull the wires as this may damage them.

DISPOSAL OF WASTE ELECTRICAL AND ELECTRONIC PRODUCTS (WEEE)

• One of the provisions of the European Directive 2002/96/CE is that anything electrical or electronic should not be treated as domestic waste and simply thrown away. To remind you of this Directive all affected products are now being marked with a crossed-out wheelie bin symbol, as depicted below.
• To comply with the Directive, you can return your old electro-therapy unit to us for disposal. Simply print a postage-paid PACKETPOST RETURNS label from our website www.tenscare.co.uk, attach this to an envelope or padded bag with the unit enclosed, and post it back to us. Upon receipt, we will process your old device for components recovery and recycling to help conserve the world’s resources and minimise adverse effects on the environment.
