AUVON AS8019 User Manual
1. Explanation of Pain
Pain is a warning system indicating something is wrong. It's crucial for detecting abnormal conditions and preventing damage. While a necessary signal, persistent pain can be purposeless. Pain messages travel from the injured area via nerves to the spinal cord and then to the brain for interpretation.
2. Explanation of TENS
Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive, drug-free pain control method. It uses electrical impulses through the skin to nerves to modify pain perception. TENS helps manage pain but does not cure underlying physiological problems. It is effective for many patients in reducing or eliminating pain, allowing them to return to normal activities.

11. Trouble Shooting
If the device is not operating properly, check the following common problems and solutions. If the issue persists, contact the seller.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pads don't work. | Only apply 1 pad on the skin. | Attach a pair of pads (of the same channel) on the skin. |
| Did not set the intensity. | Increase the intensity of the connected channel. | |
| Poor connection between the pads and the device. | Connect both ends of the lead wires to the pads and device tightly, or change a new lead wire. | |
| Poor contact between the pads and skin. | Attach the pads tightly to the skin (ensure no hair obstructs). | |
| Pads don't stick to the skin. | The transparent film is still on the pad. | Peel off the film on the adhesive surface of the pads. |
| Apply the pad immediately after washing. | Dry the pad. | |
| The gel was damaged. | Replace the pad. | |
| Pads get deteriorative. | Contact the vendor for replacements. | |
| The pads are stored under extreme conditions. | Replace the pad. | |
| One pad feels stronger than the other. | Different body areas react differently. | Ensure pads are moist and make good contact. |
| Poor wire contact. | Plug the wire into the output port completely. If it doesn't work, replace the wire and try again. | |
| The skin turns red or the skin feels irritated. | The gel was dry or contaminated. | Add a few drops of water to moisten the gel, or clean under running water for a few seconds. |
| Excessive usage time or the intensity is too high. | Reduce application time or decrease intensity. | |
| The electrode pad surface is worn out. | Replace the electrode pad. | |
| Can't plug the lead wires into the device port or the pad connector. | The lead wires are connected backwards. | The side with 1 connector is for the device port; the side with 2 connectors is for electrode pads. Ensure correct operation. |
| Incompatible connector or damaged connector/port. | Use a compatible lead wire. If provided lead wires are broken or incompatible, contact AUVON. | |
| Can't turn on the device. | Low battery. | Charge the battery. |
| Operate the wrong on/off button. | Long press the center button for 3 seconds to turn the unit on. | |
| The device is charging. | Unplug the charging cable and then use it. | |
| Something is wrong inside the device. | Contact AUVON if the device still cannot be turned on after trying all solutions. | |
| Can't adjust the mode/intensity/time. | Adjust the intensity for the wrong channel. | To adjust intensity for channel A, ensure the "A" icon is selected and flashing. |
| The screen is locked. | Press the center button or tap the lock icon to unlock the screen if a lock icon is present. | |
| The intensity felt is very weak. | Pads are not attached to the body firmly. | Attach both pads firmly to the skin. |
| The transparent films are still on the pads. | Peel the film off the pads. | |
| The pads stack together or overlap. | Do not stack or overlap pads. | |
| The cord is not properly connected to the unit. | Connect the cord correctly into the port. | |
| The intensity is too low. | Increase the intensity level. | |
| Low battery. | Charge the battery. | |
| Can not charge. | Operate the wrong port. | Find the charging port per the illustrations in the user manual and plug in the cable to charge. |
| The USB is not connecting correctly. | The charging port is narrow at the top and wide at the bottom; check the direction before inserting. | |
