What is it?
The Dual Channel Pain Relief Device ACRL-3001 is a two output channel TENS machine and is highly effective in relieving pain. TENS is now regularly recommended by doctors, physiotherapists and pharmacists throughout the world.

HOW TENS WORKS FOR PAIN RELIEF
Transcutaneous Electrical Nerve Stimulation (TENS) is a noninvasive, drug-free method of controlling pain. TENS uses tiny electrical impulses sent through the skin to the nerves to modify 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?
Scientific theory suggests that electrical stimulation therapy may work in several ways:

• the gentle electrical pulses move through the skin to nearby nerves to block the pain messagefrom the source of pain from ever reaching the brain.
• The gentle electrical pulses increase the production of endorphins, the body’s natural pain killer.

HOW TO CONTROL AND REDUCE YOUR PAIN

When should the device be used?
Use as soon as your pain begins. Start with one session. The unit automatically turns off at 30 minutes. If you treat your pain early, it may prevent the pain from becoming worse, or even chronic. It is better to get pain under control sooner so you do not reach such a high pain threshold that it limits your daily activities.
How to choose the treatment program?
This device supplies two groups of programs to treat different parts of the body and pain. Each treatment part has two treatment programs. For instance, P6 and PE-NECK can be used for treatment of neck pain. If your pain does not improve, and you become sore from over-use after the cycle, choose the other program for future treatment. Normally, we recommend you use PE programs first.

How long should you use the device?
Start with one 30-minute session. Always turn unit off with pads still adhered to the skin. Rate your pain to check your progress, (1) low to (25) high. Intensity is based upon your level of comfort. Begin the first session with a low intensity and a short duration while learning how to operate the device. Stop the therapy session if pain has reduced or stopped. If your pain does not improve and you become sore from over-use, refrain from treating those areas for two (2) days. If this issue reoccurs, reduce the treatment time and intensity settings for future treatment.

Recommended treatment sessions as follows:

When to stop using device

1. If you experience an adverse reaction— skin irritation/redness / burns, headache or other painful sensation— or if you feel any unusual discomfort.
2. If your pain does not improve, becomes seriously chronic and severe, or continues for more than five (5) days.
   NOTE:
   If you feel pain, dizziness, discomfort or nausea, call your physician or medical practitioner.

What type of pain is TENS best for?
This therapy works best on acute pain because it is localized. Acute pain occurs in one area for less than three (3) months. If you have chronic pain, you may have pain in more than one area and for longer than six (6) months. Chronic pain may be compounded by other issues that this device cannot address.
Remember this device does not cure your pain or the original cause of the pain. It provides temporary relief or reduction of pain so that you can control your life and activities better.

NOTE I: At 80 MHz ends 800 MHz the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, 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, 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 3 V/m.
