2ACD4HD-5N-RXHiDow Wireless Tens/EMS System

1 FDA CLEARED for OVER THE COUNTER SALES (OTC) – NO PRESCRIPTION REQUIRED HiDow Wireless Tens/EMS Systems WIRELESS DEVICE INSTRUCTION MANUAL 2 INTRODUCTION TO TENS EXPLANATION OF PAIN Pain is a warning system and the body’s method of telling us that something is wrong. Pain is important; without it 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. Aside from its value in diagnosis, long-lasting persistent pain serves no useful purpose. Pain does not begin until coded message travels to the brain where it is decoded, analyzed, and then reacted to. The pain message travels from the injured area along the small nerves leading to the spinal cord. Here the message is switched to different nerves that travel up the spinal cord to the brain. The pain message is then interpreted, referred back and the pain is felt. EXPLANATION OF TENS Transcutaneous Electrical Nerve Stimulation is a non-invasive, drug-free method of controlling pain. TENS uses tiny electrical impulses sent through the skin to nerves to modify your pain perception. TENS does not cure any physiological problem; it only helps control the pain. TENS does not work for everyone; however, in most patients it is effective in reducing or eliminating the pain, allowing for a return to normal activity. HOW TENS WORKS There is nothing “magic” about Transcutaneous Electrical Nerve Stimulation (TENS). TENS is intended to be used to relieve pain. The TENS unit sends comfortable impulses through the skin that stimulate the nerve (or nerves) in the treatment area. In many cases, this stimulation will greatly reduce or eliminate the pain sensation the patient feels. Pain relief varies by individual patient, mode selected for therapy, and the type of pain. In many patients, the reduction or elimination of pain lasts longer than the actual period of stimulation (sometimes as much as three to four times longer). In others, pain is only modified while stimulation actually occurs. You may discuss this with your physician or therapist. EXPLANATION OF 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; this causes the muscle to exercise passively to promote healing. It is a product derived 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. EMS has low frequency and this in conjunction with the square wave pattern allows direct work on muscle groupings. This is being widely used in hospitals and sports clinics for the treatment of muscular injuries and for the re-education of paralyzed muscles, to prevent atrophy in affected muscles and improving muscle tone and blood circulation. HOW EMS WORKS EMS is intended to be used to increase blood circulation, loosen tight and knotted muscles, stimulate muscle growth and also reduces stiffness in muscle joints. The EMS units send comfortable impulses through the skin that stimulate the nerves in the treatment area. When the muscle receives this signal it contracts as if the brain has sent the signal itself. As the signal strength increases, the muscle flexes as in physical exercise. Then when the pulse ceases, the muscle relaxes and the cycle starts over again, in a cycle of Stimulation, Contraction and Relaxation. 3 THE WIRELESS TENS/EMS - GENERAL DESCRIPTION The HiDow WIRELESS TENS/EMS System is a battery operated WIRELESS pulse generator that sends electrical impulses from a REMOTE control to RECEIVERS (round) with ELECTRODES attached to them that are placed on the body to stimulate the nerves causing pain. When this happens, the nerves “FEEL” gentle electrical sensations instead of the pain. The System is provided with 1 REMOTE and 2 RECEIVERS called CHANNEL 1 and CHANNEL 2 with each having DUAL outputs, independent of one other. THE WIRELESS REMOTE controls the ON/OFF of the system, the INTENSITY and the MODE functions of each RECEIVER. Each RECEIVER with the electrodes attached to it adheres easily and firmly to the skin. Press buttons are very easy to use and the liquid crystal display LCD shows the exact modes and values of the TENS or EMS functions being used. See the pictures in this Manual that show the different COMPONENTS and CONTROLS of the HiDow System and how to operate it properly to get the best PAIN RELIEF. Because the HiDow system is WIRELESS - Needing No Lead Wires - you must use only HiDow SNAP PIN Electrodes. Lead wire electrodes will not work with this WIRELESS system. 4 QUICK START GUIDE to USE your HiDow WIRELESS TENS/EMS System 1. Charge up both the RECEIVERS and the REMOTE with the AC power cord 2. TURN the RECEIVERS “On” and the REMOTE “ON” and see the lights on both lit 3. Snap ELECTRODES onto the RECEIVERS and place them in the pain area 4. CHOOSE RECEIVER - CHANNEL 1 or 2 by adjusting “C” on the REMOTE and seeing 1 or 2 in the LCD display 5. SET MODE of RECEIVER to MODE1, MODE2, MODE3, or MODE4 by adjusting “M” on REMOTE and seeing 1,2,3,4, in the LCD display 6. ADJUST INTENSITY of RECEIVER + or - until the sensation is felt as comfortable 5 INSTRUCTIONS FOR USE PAIN RELIEF MADE SIMPLE - THE REMOTE CONTROL The REMOTE CONTROL is the sleek looking handset. It has an LCD display, INTENSITY UP and DOWN + and - , chooses RECEIVER CHANNELS 1 and Channels 2 and a MODE button to control the MODE FUNCTIONS of the RECEIVERS. ON/OFF – IS THE BUTTON ON the SIDE of the REMOTE, to turn it “On” and “OFF”. If the LCD is blank the unit is “OFF” or the REMOTE and RECEIVERS needs to be recharged. INTENSITY When you turn the unit “ON” the INTENSITY is down to its LOWEST POINT and returns there when you turn the unit “OFF”. OUTPUT INTENSITY is on the REMOTE just below the LCD Screen figured as + - Thes…
