AUVON TU2224-A TENS Unit Muscle Stimulator

Explanation of TENS & EMS

• Transcutaneous Electrical Nerve Stimulation (TENS) 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, and it only helps control pain. TENS does not work for everyone, but for most patients it is effective in reducing or eliminating pain, allowing them to return to normal activities.
• Electrical Muscle Stimulation (EMS) stimulates the muscles rather than the nerve cells. EMS stimulates your motor nerves, which induces muscle contractions and mimics the way they contract during a workout. It will force the muscles to rapidly contract and relax.

Operating Instructions

Note Before Use

• Do not use this device during charging. (Fully charged in 2-3 hours.)
• The backlight of the screen will automatically come off after 20 seconds of no operation; when the device has no output, it will automatically shut down if there is no further operation within 5 minutes.

How to Use

1. Clean and dry your skin before use and choose the unbroken, no-hair, and flat areas with no sweat and no oil.

2. Connect a pair of electrode pads to one lead wire and plug the other end into the device.

3. Attach at least one pair of electrode pads to the massage area and press the edge of the pads firmly on your skin to ensure full contact.(Make sure the unit is off when you attach the pads.)
   Note: Make sure both pads on the skin are not overlapping. The electrode pads should be at least one inch apart from each other. Each lead wire needs to be connected to a pair of pads (2 pads), or it won’t work.

4. Press the button for 2-3 seconds to turn on the unit.
   NOTE: Do not move the electrode pads or remove the lead wires during the use, or you may be shocked.

5. Channel Option: Choose channel A/B by pressing the “A”/ “B” button or the corresponding intensity buttons on the side, and the selected channel will flash.

6. Mode Option: Press the “M-”/“M+” button to choose the mode. If “A” is flashing, it means the mode of channel A is selected. (If “B” is flashing, it means the mode of channel B is selected).
   NOTE: The intensity of the channel will revert to the lowest setting with each mode selection.

7. Intensity Option: Press the “+”/”-” button on the left/right side of the machine to adjust the intensity for the channel on which the icon is flashing.
   NOTE 1: The intensity of the channel will revert to the lowest setting with each mode selection.
   NOTE 2: For initial use, the intensity should be set between 1-3. If you feel the intensity is weak in 1-2 minutes, gradually increase it and select the most comfortable setting.

8. Time Option: Increase time by pressing the T button, and the time will increase by 10 minutes for each tap from 10 to 90 minutes and the C mode (infinite time). The device will automatically turn off when time is reached.
   NOTE 1: When the device is set in C mode and the channel has output, the message will go on until the battery is exhausted unless it is manually turned off. If the channel has no output and no operation, the machine will automatically shut down within 5 minutes.
   NOTE 2: It is recommended that each area should not use this device for more than 30 minutes at a time. Stop using it if the pain is relieved.

9. Lock Function: Press the button to lock/unlock the screen. The intensity, mode, and time options can be adjusted only when the screen is unlocked.

After Use

• Turn off the device by pressing the button for 2-3 seconds.
• Grab a corner of the electrode pad and slowly peel it away from the skin, do not pull the wire, and avoid touching the gel as much as possible.
• Place the sticky side of the pad on the trans-parent film or pad holder and remove the lead wire connector from the electrode pads gently.
• Store the electrode pads in the storage bag and reseal tightly to prevent them from dry-out. Store them at room or cool temperature (between 5 °C-35 °C/41°F-95°F) and keep out of direct sunlight. 4.3.5 Organize the wires with the cable tie and store all of them in the pouch for the store..

Charge the Battery

• When the battery icon shows “ ” or the mas-sage strength decreases, it indicates that the battery needs to charge. Turn off the unit.
• Connect the device and the charger with a USB extension cord.

It is suggested to use the AC adaptor with ANSI/AAMI/ES60601-1 certified (the de-vice does not come with a power adaptor). USB cable and please use an AC adaptor with ANSI/AAMI/ES60601-1 certified (the device does not come with a power adaptor) Plug the charger into any power outlet, the power box appears and blinks, and the time display value will update to the percentage of charge. All other icons are removed and not displayed.

Pad Placement Suggestion

TENS Electrode Pads & Pads Holder

Features

Instruction

1. Stick the electrode pads on the holder to avoid getting dust.
2. Wind the thread around the holder for easy use as the picture shown.
3. Step 3: Store the electrodes in the storage bag and reseal them.

Electrode Pads Care and Storage

• Do not cover the sticky side of the electrode pads with subjects like dry paper or dust, if you do, please drop a few drops of water and clean with finger pulp to remove dirt.
• To extend the electrode pads’ lifespan, drop a few drops of water on the sticky side and dry it naturally on the pad holder with the gel side facing up, then it will become sticky again. (Excessive water will de-crease the stickiness.)
• Cover the sticky side of the electrode pads with the transparent film, and store them in the sealed bag.(Dust on the gel will decrease the stickiness of the electrode pads.)
• Please store the electrode pads in a cool (between 5°C-35°C/41°F-95°F) and dry place. Do not expose the electrode pads to sunlight or any extreme tem-peratures to prolong the lifespan of the electrode pads.
• When the electrode pad has the following condi-tions, please do not use it and promptly replace it: gel melting; gel damaged; electrode pads not stick-ing; electrode pads deformed.

Electrode Pads Precautions

• Do not use it when driving a motor vehicle, bathing, showering, swimming, or exercising.

• Do not use the following areas: heart, spine, eyes, mouth, carotid artery, or throat; broken, excessively swollen and red, infected and inflamed, or rash skin (e.g. phlebitis, thrombophlebitis, varicose veins).

• Do not apply ointment or solvent to the electrode pads or the area where to be used.

• The electrode pads should not touch metal objects like belt buckles, necklaces, or other metal worn un-der clothes.

• Please refer to the following principles when using:

  • During use, please ensure your hands and appli-cation area are clean and dry to avoid electric shock when inserting and removing electrode pads and wires.
    Please attach electrode pads to a flat area to en-sure the electrode does not warp. Avoid placing the electrode pads on joints such as the knee, elbow, ankle, etc.
    Do not overlap or bend the electrode pads when applying to the skin, or the device may stop working, and the gel may be damaged when separating. The electrode pads should be at least one inch apart from each other. Changing the distance between the elec-trode pads or the orientation of the electrode pads can change the electrical sensation.

  • Ensure each connection port is well connected before use, or the current may be unstable. Do not move the electrode pads or unplug the lead wires by hand during the usage, or you will be shocked.
    It is recommended to use the electrode pads for 20-30 minutes per part, 1-2 times a day, with the in-tensity based on personal feeling. Attaching the pads to one area for a long time will make the skin un-breathable and lead to redness or itching. If your skin is irritated during the use, stop using the electrode pads and consult your doctor.

  • Please turn off the unit first and remove the pads from your skin, or you will be shocked.
    When removing the electrode pads, grab the cor-ner of the electrode pad with your finger pulp and peel it off, do not touch the gel with your nail, and do not pull the wire, or the electrode pad and lead wire will be damaged.

• Keep electrode pads out of the reach of children or pets.
