  • Page 4: Introduction

    1. INTRODUCTION 1.1 General information: This TENS is a lightweight and portable medical device which can help to reduce pain and discomfort. It utilizes low electric-current to stimulate muscle nerves to achieve the symptomatic relief of chronic intractable pain, post- traumatic and post-surgical pain.

  • Page 5: Precautions

    1.4.5 Stimulation should not be applied over swollen, infected, or inflamed areas or skin eruptions, e.g., phlebitis, thrombophlebitis, varicose veins, etc. 1.4.6 Stimulation should not be applied over, or in proximity to, cancerous lesions. 1.4.7 For external use only. 1.4.8 Do not use TENS on the eye area. 1.4.9 This device should be used only under the continued supervision of a licensed medical practitioner.

  • Page 6: Adverse Reactions

    (c)Over the menstruating or pregnant uterus (d)Over areas of the skin which lack normal sensation. 1.5.4 Some patients may experience skin irritation or hypersensitivity due to the electrical stimulation or electrical conductive medium. The irritation can usually be reduced by using an alternate conductive medium, or alternate electrode placement.

  • Page 8 Knob Cover: An acrylic knob cover protects Amplitude Controls from accidental user touch when the unit is being used. After adjusting the output, remember to have the cover closed. Lid Cover: A panel covers the controls for Mode, Set, INCREASE and DECREASE adjustments. Your medical professional may ask to set these controls for you and request you leave the cover in place.
  • Page 9 "DECREASE" control button (inverted triangle-button) This button decreases the pulse width from 300~50µs, decreases the pulse rate from 150 to 2Hz, and decreases the timer in continuous mode to from 90 to 5 min. "MODE" button (round-button on the right side of the control panel) This button selects a Stimulation-Mode.

    3.STIMULATION MODES The Stimulation Mode button is located under the front lid cover and is adjusted by pressing the "MODE" control button. Be sure that when adjusting these stimulation modes, the intensity (amplitude) output controls are set to the minimum output positions. 3.1 BURST Mode: The burst mode provides a "burst"...
  • Page 11 3.3 MRW (Modulated Rate and Width) Mode: The pulse rate and width are automatically varied in a cycle to produce a pleasant, massage-like sensation. It's believed that nerves can become accustomed to, or "accommodated" to the same electrical stimulus after a period of time and thus would require increasing the intensity to further block the pain.
  • Page 12 3.4 SD (Strength Duration) Mode: Strength-Duration modulation consists of alternating modulated intensity and pulse width, so the intensity is always increasing while the pulse width is decreasing and vice-versa. The stimulation intensity is modulated to 62.5% maximum of setting (width equal to setting). The pulse width is modulated to 67% of setting (intensity equal to setting).

    4. INSTRUCTIONS FOR USE NOTE: Always read this instruction manual before use. PREPARATION FOR USE 4.1 Check Battery: Insert a fresh 9V alkaline or rechargeable battery into the battery compartment. Make sure that you are installing the battery properly. The battery is inserted in the casing on the back of the stimulator unit. BE SURE TO MATCH THE POSITIVE AND NEGATIVE ENDS OF THE BATTERY TO THE MARKINGS IN THE BATTERY COMPARTMENT OF UNIT.

    CONNECTING THE STIMULATOR 4.2 Connect electrodes to lead wires: Insert the lead wire connector into electrodes connector (standard 0.08 inch female connection). MAKE SURE NO BARE METAL OF THE PINS IS EXPOSED. Caution: * Always use the electrodes with the requirements of the EN60601-1 and EN60601-2, such as with CE mark, or which are legally marketed in the US under 510(K) procedure.

    4.4 Place electrodes on skin: Apply electrodes to the exact site indicated by your physician following the instruction included with the electrodes labeling. Before applying electrodes, be sure the skin surface over which electrodes are placed is thoroughly cleaned and dried. Make sure the electrodes are placed firmly to skin and make good contact between the skin and the electrodes.

    4.6 Select the mode: Press "MODE" button to set the stimulation mode recommended by your physician or therapist. For details about stimulating waveform and sequences, please refer to Sec. 3 "Stimulation Modes". Caution: Consult physicians for your suitable stimulation mode. 4.7 Adjust the Pulse Rate: The pulses rate are adjustable 2~150Hz.

  • Page 18: Adjust The Pulse Width

    4.8 Adjust the Pulse Width: The pulse width is adjustable 50~300µs in 10µs increments. Press the SET button to enter the Pulse Width set function, then press INCREASE or DECREASE buttons to adjust Pulse Width to the setting recommended by your medical professional. 4.9 Adjust Timer: The timer is adjustable 5~90 minutes or continuous in 5 minute increments.
