01. Introduction

Unifit combines the treatment capabilities of a TENS device, an EMS or NMES device, and a relaxing massage stimulator in one unit.

It sends a small and gentle stimulation (similar to your natural nerve impulses) to the muscles being treated via two or four auto-adhesive electrode pads, in order to help you to firm and tone your body.

Rehabilitation: neuromuscular facilitation, muscle re-education, muscle training, prevention/slowing of atrophy/hypotrophy. EMS has been shown to improve blood flow and circulation.

Sports training: improve muscle strength and performance; warm up, strength, speed, power, resistance, endurance and recovery.

Muscle relaxation: loosening up of muscular tension, improving muscular fatigue symptoms and reduced fatigue and muscle tension.

02. Intended Use

Unifit is a medical device designed to be used in the home healthcare environment to improve muscle tone and bulk, as well as provide symptomatic relief and management of acute or chronic localised pain and muscle pain. It is suitable for use by all who can control the device and understand the instructions.

Do not use the device for any purpose other than this intended use.

Warning: Not suitable for use in children without medical supervision.

04. Safety Guidelines

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 and EMS may affect foetal development.
• Do not use on the abdomen in the later stages of pregnancy. Stop using 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 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 spread of cancer cells.

• Do not use simultaneously with high frequency hospital diagnostic/therapeutic equipment. Doing so may result in burns at the site of the electrodes and possible damage to device.
• 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 in close proximity (e.g. 1 m) to a shortwave or microwave as this may produce instability in the stimulator output.
• Do not apply near the thorax because the introduction of electrical current may increase the risk of cardiac fibrillation.
• Stimulation should not be applied across or through the head, directly on the eyes, covering the mouth, on the front of the neck (especially the carotid sinus), or from electrodes placed on the upper back or crossing over the heart.

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.
• Do not permit use by children unable to understand the instructions or persons with cognitive disabilities, i.e.; Alzheimer's disease or dementia.
• Keep away from children under 5 years of age, pets and pests. Long lead wires and charging cables - risk of strangulation in infants.
• Caution should be observed when using Unifit at high strength settings. Prolonged use at high settings may cause muscle injury or tissue inflammation. Unifit is capable of delivering outputs in excess of 10 mA (RMS) or 10 V averaged over any period of 1 sec.
• Not intended for use in an oxygen rich environment.

- Not intended for use in conjunction with flammable anaesthetics or flammable agents.

• The patient is an intended operator.

- Do not service and maintain the device while in use with a patient.

- Maintenance and all repairs should only be carried out by an authorized agency. The manufacturer will not be held responsible for the results of maintenance or repairs by unauthorized persons.

- If necessary, we will provide circuit diagrams, component part lists or other information that will assist authorized service personnel to repair the device.

- Do not immerse your device in water or place it close to excessive heat such as a fireplace or radiant heater or sources of high humidity such as a nebulizer or kettle as this may cause it to cease to operate correctly.

- Keep the device away from sunlight, as long-term exposure to sunlight may affect the rubber causing it to become less elastic and crack.

- Keep the device away from lint and dust, as long-term exposure to lint or dust may affect the sockets or cause the battery connector to develop a bad contact.

- Temperature & Relative Humidity of storage: -10^ - + 45^ ( ≤ 3 months), 15% -75% R.H. Temperature & Relative Humidity of transportation: -10^ - + 60^, 15% -75% R.H.

- There are no serviceable user parts. Do not attempt to open or modify the unit. This may affect the safe operation of the unit and will invalidate the warranty.

Note: There are no known side effects to use and long-term use is not harmful. However, the device works your muscles and unaccustomed amounts of exercise may produce muscle ache. If this happens, simply reduce the strength of the machine or allow your muscles to rest until the aching disappears.

Electrode Pad Cautions

• Do not ignore any allergic reaction to the electrode pads: If a skin irritation develops, stop using the device, as this type of electrodes may not be suitable for you. Alternative electrode pads specially made for sensitive skin are available.
• Do not use this device with leads or electrode pads other than those recommended by the manufacturer. Performance may vary from specification. Electrodes with smaller surface area may cause tissue irritation.
• Do not use electrodes smaller than 50x50mm.

Do not place electrode pads:

- On skin, which does not have normal sensation. If the skin is numb too great a strength may be used, which could result in skin inflammation.

• On broken skin. The electrode pads could encourage infection.
• On the front of the neck. This could cause the airway to close, giving breathing problems. May cause sudden drop in blood pressure (vasovagal response).
  • Over the eyes. May affect eyesight or cause headaches.
• Across the front of the head. Effect on patients who have had strokes or seizures is not known. May affect your sense of balance. The effects of stimulation on the brain are unknown.

06. Directions for Use

Connecting the Lead Wires and Pads

1. Insert the lead wire plug into the base of the unit.
2. Attaching the electrode pads to the lead wire. Push the pin ends firmly into the pigtail ends of the electrode pads.
3. Before applying the electrode pads to your body, make sure your skin is clean and dry.
4. Place the electrode pads on the skin (see Pad Placement).

Warning: Ensure Unifit is switched off before applying the electrode

pads on the skin.

Turning Unifit On

To turn the unit on, press the Power button on the side of the device for approximately 1 second until the display shows. The unit will start with the programme you used last.

Unifit will automatically turn off if both strength controls are set to zero for 5 minutes.

Mode and Programme Selection

1. Press the mode selection button to scroll through and select the desired mode.

2. Once you have selected the mode, press the programme selection button to scroll through and select the programme of choice.

Each time you change the mode or programme, the intensity level will revert to zero. This is a safety feature to alleviate any sudden feeling of a surge, as each programme gives a different sensation.

Selecting Treatment Time

The default treatime time for preset programmes is shown. For relevant programmes, treatment time can be changed by pressing the settings button. Use CH2▲▼ to select the preferred treatment time. You can select between 5 - 90 minutes or continuous (marked as C).

Setting the Intensity

Once the electrode pads have been connected and applied to the body and the programme has been selected, the intensity levels can be adjusted. Unifit has 99 levels of intensity.

CH1▲ CH1▼ control the intensity of the left-hand lead/electrode pads. CH2▲ CH2▼ control the intensity of the right-hand lead/electrode pads. Each press of the ▲ and ▼ buttons will adjust the intensity by 1mA. The intensity can be increased or decreased quickly by pressing and holding the ▲▼ buttons.

At low intensity levels, it is common for no sensation to be felt. Continue to increase the intensity until the sensation is strong but comfortable.

During a session, your body can become used to the sensation. If this is the case, increase the intensity levels.

The intensity controls will not operate unless the Unifit has been properly conenected to the body. If the Unifit detects a disconnection on either channel, the intensity will rest to 0mA and the connection error icon will flash. This is a safety feature designed to prevent sudden surges in stimulation.

When an orange circle is displayed next to the intensity levels, this means the output is high enough be harmful if not used correctly. Please use with caution.

07. TENS

Programmes

Transcutaneous Electrical Nerve Stimulation provides a natural solution to pain relief in one of two ways:

- Pain Gate

Stimulates sensory nerves to block pain signals from being received from the brain.

Pain Gate Stim provides pain relief whilst being used.

• Endorphin Release

Low frequency TENS promotes the release of endorphins, the body's natural pain killer.

Endorphin Release builds up over 40 minutes and will last several hours after stimulation is ended.

- Programme Selection

There is not one programme for a particular condition, and the best choice varies from each person, even if they have the same type of pain. The "Recommended Use" are suggestions to help with programme selection. However, each user needs to select both the programme and the positioning of the electrode pads that is best for them.

- Intensity Selection

The stimulation sensation should be strong but comfortable. Further increases during use may be necessary if your body becomes used to the sensation.

- Frequency of Use

TENS can be used for as long as it is necessary. Continuous treatment is safe, but 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 best 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.

Prog	Type of Relief	Sensation	Recommended Use
1 Pain Gate		Smooth, constant sensation	For first use of TENS. These programmes have slightly different parameters so choose the one that works best for you.
2 Pain Gate		Smooth, constant sensation
3 Endorphin Tapping			For chronic pains such as back pain and arthritis
4	Pain Gate + Endorphin	Pulsing	For radiating pain in arms and legs and deep muscular pain (Osteoarthritic pain in the knee, Sciatica central pain). These programmes have slightly different parameters so choose the one that works best for you.
5	Pain Gate + Endorphin	Pulsing
6	Pain Gate + Endorphin	Alternating tapping / constant	For maximum production of the two central opioid peptides associated with pain relief. These programmes have slightly different parameters so choose the one that works best for you.
7	Pain Gate + Endorphin	Alternating tapping / constant
8	Pain Gate + Endorphin	Relaxing message sensation	Settings modulate to prevent accomodation occurring.
9	Pain Gate + Endorphin	Relaxing message sensation	Settings and intensity modulate to prevent accomodation occurring.
10 Pain Gate		Smooth, constant sensation	Treating nerve rich areas (e.g. facial pain, neck pain)
11	Pain Gate or Endorphin	Constant sensation	For manual settings control.
12	Pain Gate +/or Endorphin	Pulsing

For full programme parameters, please see section 18 Specification

08. EMS Programmes

Before selecting an EMS programme, you will need to select an EMS Mode:

EMS I

For small muscles such as those in the hands.

EMS II

For medium sized muscles such as arms and feet.

EMS III

For large muscles such as thighs, buttocks and abdomen.

EMS III

Advanced muscle mass mode for large muscle mass.

With the mode selected, please choose from one of the following programmes.

Prog Application Description
1	Muscle Calming	Relax the muscles as much as possible and to promote the body's natural endorphins to promote pain relief and to improve the blood circulation and provide oxygen into the muscle.
2	Resume Training	Promotes slow twitch fibres to build muscle strength to help reduce muscle atrophy ready for resuming training activities.
3	Resume Training	Progress from programme 2 as tolerance increases.
4	Resistance Training	Improving the capacity to develop very high level of muscle force over a long period of time. Improving the efficacy of oxygen consumption at the muscle level and the capacity to withstand toxin accretion, such as lactic acid. For sports activities that require very high levels of prolonged muscle activity: Rowing, Cycling, Middle distance running.
5	Resistance Training	Progress from programme 4 as tolerance increases. Alternative application: Lipolysis Increasing blood circulation and modifying the metabolism of the lipocytes. This helps to stimulate the subcutaneous deposits of fat, reducing or eliminating the 'Orange Peel' effect of the skin surface
6	Maximum Muscle Contraction	To increase muscle bulk and volume and to improve muscle force. Searching for muscular hypertrophy.
7	Muscle Toning	Strengthening the muscles, improving blood circulation and capillary bed density. Ideal for applying to the Thigh, Legs, Bottom and Abdomen.
8	Muscle Toning	Similar to programme 7, but adding bulk in preference to endurance
9	Force Output, Anaerobic Activity	Increasing the muscle capacity to a level of instantaneous maximum muscle force, changing muscle force into explosive action. Used for all activities requiring maximum muscle output in a very short space of time, such as Judo, short distance sprinting, throwing the discus or shot-put.
10 Manual		Select the frequency, the pulse width, the work and active rest time. At first use, the default values are shown. Note: There are two manual programmes as the device will remember your previously selected settings. This allows you to create two custom programmes.
11 Manual

For full programme parameters, please see section 18 Specification

Work / Rest Selection

When selecting work and rest times for manual programmes, the Warning triangle is displayed if the Active Rest period is less than:

Rest Time = Work Time * (WorkHz-16.66) / 16.66 seconds.

This is because muscle fibres can only activate a limited number of times a minute (about 1000) without becoming fatigued.

Warning: Consult your healthcare professional before altering these settings. Correct settings depend on your muscle tone and exercise goals. Inappropriate settings could cause discomfort, undesired muscle balance, or even muscle injury.

Intensity Selection

The aim of EMS is to produce powerful, visible muscle contractions. The intensity should be increased to roughy 3x the level at which you can first feel tingling, or to as high as you can stand without causing pain.

Use a low intensity for the first session to help you to understand how the machine works.

Intensity should be increased throughout a session and gradually over time. This will help produce effective, pain-free contractions.

Combining Voluntary Activity

Voluntary muscular activity is more effective than stimulation, and it may improve progress if you combine voluntary contraction with stimulation. For best results, always try to contract voluntarily during the work phases.

Frequency of Use

Ideally, use EMS programmes once every two days for each muscle with a day of rest in between. It is possible to work on pairs of muscles, for example thighs and abdominal muscles, treating one set one day and the other the next day.

Regular use over a period of 4 – 6 weeks should give good initial results, depending on the body shaping, toning, sports training or rehabilitation and recovery needs.

Massage programmes can be used to relieve muscle stiffness. Experiment with the different programmes to find the one that you find the most relaxing.

Programme 1 alternates between two strong squeezing/kneading feelings.

Programme 2 alternates between slow and fast tapping.

Programme 3 alternates between gentle and strong kneading.

Programme 4 has five steps of gradually increasing strength of kneading, alternating with tapping.

Programme 5 & 7 alternates between slow and medium-strong tapping.

Programme 6 is a gentler form of programme 5.

Programme 8 is a pumping sensation roughly equivalent to your heart rate, that slowly increases in speed over the course of the 20 min treatment. It is especially effective with swollen legs and veins.

Programme 9 is squeezing/kneading in 6 steps of increasing intensity.

Programme 10 generates a tapping sensation, gradually speeding up, then slowing down.

Note: There are no restrictions to the frequency of use of massage

programmes.

10. Pad

Placement

TENS Pad Placement

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.

If the pain is in, or close to, your spine you can place one pad either side of the spine.

Note: See examples of positioning in the instructions enclosed with ads.

EMS Pad Placement

Electrode placement for EMS is important for obtaining the best results.

Place two electrode pads over the bulk of the muscle, with one electrode over the muscle's motor point. The motor point is the area on the skin that is located closest to the motor nerve's entry into the muscle – about 1/3 of the way down the muscle from the spine. Here, it is easiest to trigger a contraction by electrical stimulation.

Experiment by moving the electrode pads across the skin until you locate the point over the muscle that gives the cleanest contraction.

Note: The + electrode pad needs to be plugged in to the red lead

wire connector, the - pad to the black lead wire connector.

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 inside the re-sealable plastic bag.

- If the electrode pads dry out, it is recommended to buy a replacement pack. It is possible to restore some of the adhesion 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, place the electrodes sticky side up in a refrigerator for a few hours. This should help restore some adhesion.

• 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 re-sealable bag, 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.
• The electrode pads must always be used in pairs (two electrode pads on each channel), so that the signal can flow in a circuit.
• 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.
