FOREWORD

Introduction

  • The device Magic is a dual channel output TENS, EMS and MASSAGE stimulator. Before using, please read all the in­structions in this user manual carefully and keep it safe for future use.
  • The COMBO stimulator belongs to the group of electrical stimulation systems. It has three basic functions- TENS (Transcutaneous Electrical Nerve Stimulation), EMS (Elec­tronic Muscle Stimulation) and MASSAGE.
  • Function of the COMBO stimulator: The device has 22 programs ( 9 TENS programs, 8 EMS programs and 5 MASSAGE programs) and applies electric currents in the low-frequency range for therapy. Each program controls the generated electric impulses, their intensity, frequency and pulse width.
  • Based on simulating the body’s natural pulses, the mecha­nism of electrical stimulation equipment is to create elec­tric impulses that are transcutaneous transmitted to nerves or muscle fibers through the electrode. The intensity of the dual channel can be adjusted independently and app­lied individually to one body part. This dual channel device can be used with four pieces of electrodes, which allow you to stimulate one muscle groups simultaneously with a wi­de selection of standard programs. The electrical pulse is fir­stly transmitted to the tissue, then it affects the transmission of stimulation in nerves as well as muscle tissues in the body parts.

Medical background

  1. ABOUT PAIN

  2. Pain is an important signal in the human body warning sys­tem. It reminds us that something is wrong, without which, 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.

  3. Aside from its function in diagnosis, long-lasting persistent pain serves useless purpose.

  4. Pain does not occur until encoded message travels to the brain where it is decoded, analyzed, and reacted to, from the injured area along the small nerves leading to the spinal cord. There the message is transmitted to different nerves that travel up the spinal cord to the brain. Then the pain message is interpreted, referred to and pain is felt.

  5. WHAT IS TENS?
    TENS (Transcutaneous Electrical Nerve Stimulation) is ef­fective in relief of pain. It is daily used and clinically proven by physiotherapists, caregivers and top athletes around the world. High-frequency TENS currents activates the pain-in­hibiting mechanisms of the nervous system. Electrical im­pulses from electrodes, placed on the skin over or near the pain area, stimulate the nerves to block the pain signals to the brain, causing the pain go unperceived. Low-frequen­cy TENS currents facilitate the release of endorphins, the body’s natural painkillers.

  6. WHAT IS EMS?
    Electrical Muscle Stimulation is an internationally accepted and proven way of treating muscular injuries. It works by sending electronic pulses to the muscle needing treatment that causes the muscle to exercise passively. It is a product deriving from the square waveform, originally invented by John Faraday in 1831. Through the square wave pattern it is able to work directly on muscle motor neurons. The EMS System has low frequency and this in conjunction with the square wave pattern allows direct work on muscle group­ings.

  7. WHAT IS MASSAGE?
    The massage function is non-medical function. The Massage stimulation program provides relaxing muscle vibration to loosen tight muscles.

SAFETY INFORMATION

Intended use

  • TENS mode
    It is used for temporary relief of pain associated with sore and aching muscles in the neck, shoulder, back, upper extremities (arm) and lower extremities (leg) due to strain from exercise or normal household work activities.

  6. Inguinal hernia.

  7. Do not use on scarred areas following a surgery for at least 10 months after the operation.

  8. Do not use with serious arterial circulatory problems in the lower limbs.

WARNING

  1. If you have had medical or physical treatment for your pain, consult with your physician before use.
  2. If your pain is not subdued, whice becomes more th­an mild, or lasts for more than five days, stop using the device and consult with your physician.
  3. Do not apply stimulation over your neck because this could cause severe muscle spasms resulting in closure of your airway, difficulty in breathing, or adverse effects on heart rhythm or blood pressure.
  4. Do not apply stimulation across your chest because the introduction of electrical current into the chest may cause rhythm disturbances to your heart, which could be lethal.
  5. Do not apply stimulation over, or in proximity to, can­cerous lesions.
  6. Do not apply stimulation in the presence of electronic monitoring equipment (e.g., cardiac monitors, ECG alarms), which may not operate properly when electri­cal stimulation device is in use.
  7. Do not apply stimulation when in bath or shower.
  8. Do not apply stimulation while sleeping.
  9. Do not apply stimulation while driving, operating ma­chinery, or during any activity when electrical stimula­tion can put you at risk of injury.
  10. Apply stimulation only to normal, intact, clean, healthy skin.
  11. The long-term effects of electrical stimulation are un­known. Electrical stimulation device cannot replace drugs.
  12. Stimulation should not take place while the user is con­nected to high-frequency surgical equipment, which may cause burn injuries on the skin under the elec­trodes, as well as problems with the stimulator.
  13. Do not use the stimulator in the vicinity of shortwave or microwave therapy equipment, since this may affect the output power of the stimulator.
  14. Never use it near the cardiac area. Stimulation electrodes should never be placed any  where on the front of the thorax (marked by ribs and breastbone), but above all not on the two large pectoral muscles. There it can increase the risk of ventricular fibrillation and lead to cardiac arrest.
  15. Never use it on the eye, head and face area.
  16. Never use it near the genitals.
  17. Never use it on the areas of the skin which lack normal sensation
  18. Keep electrodes separate during treatment. It could re­sult in improper stimulation or skin burns if electrodes a re in contact with each other.
  19. Keep the stimulator out of reach of children.
  20. Consult your doctor if you are in any doubt whatsoever.
  21. Discontinue it and do not increase the intensity level if you feel discomfort during use.

Precautions

  1. TENS is not effective for pain of central origin including headache.
  2. TENS is not a substitute for pain medications and other pain management therapies.
  3. TENS is a symptomatic treatment and, as such, sup­presses the sensation of pain that would otherwise serve as a protective mechanism.
  4. Effectiveness is highly dependent upon patient selec­tion by a practitioner qualified in the management of pain patients.
  5. Since the effects of stimulation of the brain are un­known, stimulation should not be applied across your head, and electrodes should not be placed on opposite sides of your head.
  6. The safety of electrical stimulation during pregnancy has not been established.
  7. You may experience skin irritation or hypersensitivity due to the electrical stimulation or electrical conduc­tive medium (silica gel).
  8. If you have suspected or diagnosed heart disease or epilepsy, you should follow precautions recommended by your physician.
  9. Caution if you have a tendency to bleed internally, e.g. following an injury of fracture.
  10. Consult with your physician prior to use the device after a recent surgical procedure, because stimulation may disrupt the healing process.
  11. Caution if stimulation is intended to be applied over the menstruation or pregnant uterus.
  12. For single patient use only.
  13. This stimulator should not be used by patients who is noncom pliant and emotionally disturbed including whom with dementia or low IQ.
  14. The instruction of use is listed and should be obeyed; any improper use may be dangerous.
  15. Rare cases of skin irritation may occur at the site of the electrode placement following long-term application.
  16. Do not use this device in the presence of other equip­ment which sends electrical pulses to your body.
  17. Do not use sharp objects such as a pencil or ballpoint tip to operate the buttons on the control panel.
  18. Check the electrode connections before each use.

For TENS Programs
When using any of the TENS programs for pain relief always start with the lowest intensity and gradually increase the level of intensity until you feel a “tingling” sensation. All programs are different and therefore feel differently. You may try all programs in the beginning and choose one that feels pleasant. Never increase the intensity to a level so that it hurts, always stay under the point of discomfort. Start with short sessions of 5 or 10 minutes until your body gets used to the stimulation.

Mode Program NO. You should feel
TENS 1 Continuous comfortable tingling. The underlying pain should

decrease gradually after treatment.
2| Two channels output alternately, with a sense of ‘work’ and ‘rest’
3| Comfortable pulsing sensation. The underlying pain should decrease almost immediately.
4| Variable comfortable tingling and pulsing sensation (sensation should appear to come in waves). Pain should ease and there should be relief aftertreatment
5| Continuous comfortable tingling. The underlying pain should decrease gradually after treatment.
6| Variable comfortable tingling and pulsing sensation (sensation should appear to come in waves). Pain should ease and there should be relief after treatment
7| Continuous comfortable tingling. The underlying pain should decrease gradually after treatment.
8| Variable comfortable mild tingling sensation (sensation will appear to come in waves}.
9| sensation will appear to come in waves

For EMS Programs
When using the device for muscle stimulation (EMS) any of the 8 programs may be used. The intent is to cause a muscle to contract, and then release. All 8 programs will achieve contraction and vary mainly by the rate and duration of the contractions. As with any exercise regiment, start out slowly with low intensity levels for a warm-up (5~ 10 min). You may increase intensity level and treatment time as you progress with your muscle performance. Use the device regularly over a longer period of time as to maintain the benefit you may have gained during “exercise” .

  • Ensure the electrode wires are inserted correctly. The de­vice has two output receptacles controlled by Channel A and Channel Bat the top of the unit. You may choose to use one channel with one pair of electrode wires or both channels with two pairs of electrode wires.
  • Using both channels gives the user the advantage of stimu­lating two different areas at the same time .

Caution
Do not insert the plug of the electrode wires into any AC power supply socket.

Electrode

  1. Electrode options
    The electrodes should be routinely replaced when they start to lose their adhesiveness. If you are unsure of your electrode adhesive properties, please order new replace­ment electrodes. Replacing electrodes should be re-or­dered under the advice of your physician or the device manufacturer to ensure proper quality. Follow application procedures outlined on electrode packing when using the new replacement electrodes to maintain optimal stimula­tion and to prevent skin irritation.

  2. Place electrodes on skin
    Place the electrode on the body part in need of treatment, according to the instruction of this user manual. Please make the skin clean before use and ensure the skin and electrode connect well.

Caution

  1. Always remove the electrodes from the skin with a mod­erate pull in order to avoid injury in the event of highly sensitive skin.
  2. Before applying the self-adhesive electrodes, it is recom­mended to wash and degrease the skin, and then dry it.
  3. Do not turn on the device when the self-adhesive elec­trodes are not positioned on the body.
  4. To remove or move the electrodes, switch off the device or the appropriate channel first in order to avoid unwant­ed irritation.

  • Make sure that the device is no longer connected to the patient (the output cables and electrodes must be dis­connected).
  • Connect the USB cable to the charging port on the device.
  • Connect the USB cable to the charger.
  • When the device is charging, the indicator light will be red.
  • It could take up to 2 hours to reach a full charge.
  • When charging is completed, the indicator light will be green.

The life of a rechargeable battery depends on the number of recharging/rundown cycles it undergoes and how these cycles are performed.

The following suggestions will help prolong the life of the battery

  • Whenever the device is not used frequently, charge the battery once a month.
  • For longer battery life, discharge the battery as much as possible.

Usage of electrode pads

  1. The electrode may only be connected with the COMBO stimulator. Make sure that the device is turned off when attaching or removing the electrode pads.
  2. If you want to reposition the electrode during the appli­cation, turn the device off first.
  3. The usage of electrode may lead to skin irritations. If you experience such skin irritations, e.g. redness, blistering or itching, discontinue using them. Do not use the COMBO stimulator permanently on the same body part, as this may also lead to skin irritations.
  4. Electrode pads are private and intended for single per­son use. Please avoid using them by different persons.
  5. The electrode must connect entirely to the skin surface to prevent hot spots, which may lead to skin burns.
  6. Do not use the electrode pads for more than approx. 10 times, as connection between the electrodes and the skin deteriorates over time.
  7. The adhesive force of the electrodes depends on the skin properties, storage condition, and the number of applications. If your electrode pads no longer fully stick to the skin’ surface, replace them with new ones. Stick the electrode pads back onto the protective foil after use and store them in the storage bag to prevent them from drying out. This retains the adhesive force for a longer period.

Caution:

  1. Before applying the electrode, it is recommended for us­ers to wash and degrease the skin, and then dry it.
  2. Never remove the electrode from the skin while the de­vice is still on.
  3. Only use the electrode pads provided by the manufac­turer. Usage of other companies’ products could result in injuries to the user.

Where do I attach electrode pads?

  1. Each person reacts differently to electric nerve stimu­lation. Therefore, the placement of the electrodes may deviate from the standard. If application is not success­ful, contact your physician to find out which placement techniques are best for you.
  2. Do not use any adhesive electrodes with a size smaller than those the original manufacturer attached. Other­wise the current density may be too high and cause inju­ries.
  3. The size of the adhesive pads may not be changed, e.g. by clipping off parts of them.
  4. Make sure that the region radiating the pain is enclosed by the electrodes. In case of painful muscle groups, at­tach the electrodes in such a way that the affected mus­cles are also enclosed by the electrodes.

  • NOTE 1  At 80 MHz and 800 MHz, the higher frequency range applies.

  • NOTE 2  These guidelines may not apply in all situations. Elec cryomagnetic propagation is affected by absorption and reflection fr om struc t ures , objects and people.

  • Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the device.

  • Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [Vi] V/m. TENS-UNITS-Magic-Combo-Electrotherapy-Device-42 TENS-UNITS-Magic-Combo-Electrotherapy-Device-43

N O TE If it is necessary to achieve the IMMUNITY TEST LEVEL, the distance between the transmitting antenna and the ME EQUIPMENT or ME SYSTEM may be reduced to 1 m.The 1 m test distance is permitted by IEC 61000-4-3.

  1. For some services, only the uplink frequencies are included.
  2. The carrier shall be modulated using a 50 % duty cycle square wave signal.
  3. As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because it does not rep- resents actual modulation. It would be worst case.
