1. Explanation of TENS & EMS

Transcutaneous Electrical Nerve Stimulation (TENS)

TENS is a non-invasive, drug-free method of pain control. It uses tiny electrical impulses sent through the skin to nerves to modify pain perception. TENS is used for temporary relief of pain associated with sore and aching muscles in the shoulder, waist, back, neck, upper extremities (arm), and lower extremities (leg) due to strain from exercise or normal household work activities.

Electrical Muscle Stimulation (EMS)

EMS stimulates the muscles rather than the nerve cells. EMS stimulates motor nerves, which induces muscle contractions, mimicking natural muscle contraction during a workout. It forces muscles to rapidly contract and relax.

Intensity Option: To increase or decrease intensity, press the "+/-" button for the selected channel. For initial use, set intensity between 1-3. If intensity feels weak after 1-2 minutes, gradually increase it to a comfortable setting.
Time Option: Use the "T" button to set massage time from 10-90 minutes. The device will automatically turn off when the set time is complete. NOTE: 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.

4.3 After Use

Turn off the device by pressing the power button for 1-2 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 transparent film or pad holder and gently remove the lead wire connector from the electrode pads.
Store the electrode pads in the storage bag and reseal tightly to prevent dry-out. Store them at room or cool temperature (between 5 °C-35 °C/41°F-95°F) and keep out of direct sunlight.
Organize the wires with the cable tie and store all components in the pouch.

4.4 Charge the Battery

When the battery icon shows "□" (empty battery symbol) or massage strength decreases, the battery needs charging. Turn off the unit and charge it.
Connect the device and charger with a USB extension cord. Plug the charger into any power outlet. The power icon will appear and blink, and the time display will update to the percentage of charge. Other icons will not display.
The machine does not work while charging. Normal charging lasts approximately 2-3 hours. TIP: Charge the unit at least every 3 months if it is not used regularly.

6. TENS Electrode Pads & Pads Holder

6.1 Features

The pads holder is made of high-quality ABS material for safe use. It is widely compatible with pads of different sizes. The salient points on the holder are designed to lessen damage to the pads.

6.2 Instruction (Pads Holder Use)

Step 1: Stick the electrode pads on the holder to avoid getting dust. An illustration shows a hand placing an electrode pad onto the holder.
Step 2: Wind the thread around the holder for easy use. An illustration shows a hand winding the lead wire around the holder with the pads attached.

6.3 Electrode Pads Care and Storage

Do not cover the sticky side of the electrode pads with dry paper or dust. If dust accumulates, 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 sticky side facing up. This can restore stickiness. (Excessive water will decrease 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.
Store electrode pads in a cool (5°C-35°C/41°F-95°F) and dry place. Do not expose them to sunlight or extreme temperatures.
Replace electrode pads if they show signs of gel melting, gel damage, loss of stickiness, or deformation.

6.4 Electrode Pads Precautions

Do not use the device when driving a motor vehicle, bathing, showering, swimming, or exercising.
Do not use on the following areas: heart, spine, eyes, mouth, carotid artery, throat, broken skin, excessively swollen/red/infected/inflamed skin, or rash skin (e.g., phlebitis, thrombophlebitis, varicose veins).
Do not apply ointment or solvent to the electrode pads or the application area.
Electrode pads should not touch metal objects like belt buckles, necklaces, or other metal worn under clothes.
When using, ensure hands and application area are clean and dry to avoid electric shock when inserting and removing electrode pads and wires.
Attach electrode pads to a flat area to prevent warping. Avoid placing pads on joints such as the knee, elbow, or ankle.
Do not overlap or bend electrode pads when applying to the skin, as this may cause the device to stop working or damage the gel.
Electrode pads should be at least one inch apart from each other. Changing the distance or orientation of the pads can change the electrical sensation.
Ensure each connection port is well connected for stable current. Do not move electrode pads or unplug lead wires by hand during use to avoid electric shock.
It is recommended to use electrode pads for 20-30 minutes per part, 1-2 times a day, with intensity based on personal feeling. Attaching pads to one area for too long can cause skin unbreathability, redness, or itching. If skin irritation occurs, stop use and consult a doctor.
Turn off the unit first and remove pads from skin to avoid electric shock.
When removing electrode pads, grab the corner with finger pulp and peel it off. Do not touch the gel with nails or pull the wire, as this can damage the electrode pad and lead wire.
Keep electrode pads out of the reach of children or pets.
