Model AS1080

Device Name: TENS & EMS Device

Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive, drug-free method of pain control. TENS 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.

• Pin Pads
• Pads Holder
• Pouch
• Set of Electrode Wires (1/2 Wire)
• USB-C Port
• User Manual

The device features a top view with an ON/OFF switch (15) and a USB port (16). The main screen displays massage time (1), various mode icons (2-4, 8-10), intensity level (11), and battery indicator. Below the screen are controls including Mode Selection (5), Intensity Decrease (-) (6), Time Selection (7), Intensity Increase (+) (12), and a Center Button (13). The bottom of the device has two output connectors (A and B) (14).

4.1 Note Before Use

• Do not use this device during charging.
• When the device has no output and no operation, it will shut down automatically in 5 minutes.
• Users may experience tingling, trembling, or muscle pulling. Try all modes and select the most comfortable one.
• For initial use, set intensity between 1-3. Gradually increase if intensity feels weak after 1-2 minutes.
• It is recommended to use the device for 20-30 minutes and stop when pain is relieved.

4.2 How to Use

1. Clean and dry the application area. Do not attach electrode pads to hairy or broken skin.

4. Grab the corner of the electrode pad and peel it off the protective film. Do not pull the wire directly. Attach one pair of electrode pads to the massage area and press the edge firmly for full contact. For additional relief, use the second port with two additional pads. (Make sure the unit is off when attaching pads.)

   NOTE: Each lead wire needs to be connected to a pair of pads (2 pads), or it won't work.

8. Use the "T" button to set the massage time from 10-60 minutes. The time remaining is automatically counted down. The unit will automatically turn off after time is finished.

   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.

9. Long press the "T" button for 10 seconds. If all icons on the screen stop flashing, adjust backlight brightness (low, medium, highlight) with the "+" button and backlight duration (10s/30s/60s) with the "-" button (duration displayed on top left). The screen returns to original interface after 3 seconds of no operation.

4.3 After Use

1. Turn off the device by pressing the power button for seconds.
2. 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.
3. Place the sticky side of the pad on the transparent film or pad holder and remove the lead wire connector gently.
4. 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.
5. Organize the wires with the cable tie and store all of them in the pouch.

4.4 Charge the Battery

1. When the battery icon shows "□" or massage strength decreases, the battery needs charging. Turn off the unit.
2. Connect the device and charger with a USB extension cord. Plug the charger into any power outlet. The power box appears and blinks, and the time display updates to the percentage of charge. All other icons are removed.

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.

5.1 Mode Description

6.1 Features

The pads holder is made of high-quality ABS material for safe use. It features a design with numerous salient points to lessen damage to the pads. The holder is widely compatible with pads of different sizes.

6.3 Electrode Pads Care and Storage

• Do not cover the sticky side of the electrode pads with dry paper or dust. If dirt accumulates, drop a few drops of water and clean with finger pulp.
• To extend lifespan, drop a few drops of water on the sticky side and dry naturally on the pad holder with the gel side facing up; it will become sticky again. (Excessive water decreases stickiness.)
• Cover the sticky side with the transparent film and store in the sealed bag. (Dust on the gel decreases stickiness.)

6.4 Electrode Pads Precautions

• Do not use when driving a motor vehicle, bathing, showering, swimming, or exercising.
• Do not use on 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 of use.
• Electrode pads should not touch metal objects like belt buckles, necklaces, or other metal worn under clothes.
• Refer to the following principles when using:
1. Ensure hands and application area are clean and dry to avoid electric shock when inserting and removing electrode pads and wires.
2. Attach electrode pads to a flat area to ensure the electrode does not warp. Avoid placing pads on joints such as the knee, elbow, ankle, etc.
3. Do not overlap or bend electrode pads when applying to the skin, or the device may stop working, and the gel may be damaged when separating.

Electrode pads should be at least one inch apart from each other. Changing the distance or orientation of pads can change the electrical sensation.

4. Ensure each connection port is well connected before use, or current may be unstable. Do not move pads or unplug lead wires by hand during usage, or you will be shocked.
5. It is recommended to use pads for 20-30 minutes per part, 1-2 times a day, with intensity based on personal feeling. Attaching pads to one area for a long time will make skin unbreathable and lead to redness or itching. If skin is irritated, stop use and consult a doctor.
6. Turn off the unit first and remove pads from skin, or you will be shocked.
7. When removing pads, grab the corner with finger pulp and peel it off. Do not touch gel with nail, and do not pull the wire, or the pad and lead wire will be damaged.

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

7.1 Prohibited Conditions

• The wire is broken.
• The electrode pads are not sticky, deformed or damaged.
