6. Setup
6.1 Charging the Device
Before first use, ensure the acupuncture pen is fully charged. Connect the USB charging cable to the charging port on the device and to a compatible USB power adapter. The device is rechargeable and uses a lithium battery.

6.2 Attaching a Probe
Select the appropriate massage probe for your intended application:
- Big Probe: For general body areas.
- Beauty Probe: For facial applications.
- Small Probe: For ear and head areas.
Gently insert the chosen probe into the replaceable probe port at the tip of the pen until it is securely in place.

7. Operating Instructions
Follow these steps for effective use of your acupuncture pen:
- Adjust Settings: Before starting, adjust the intensity, sensitivity (SEN), and frequency (Hz) knobs to your desired levels. Start with lower settings and gradually increase as needed.
- Proper Grip: Hold the pen firmly with your thumb in contact with the metal conduction area on the side of the pen. This completes the circuit necessary for operation.
- Acupoint Searching: Gently slide the pen tip along the skin in the area you wish to treat. As the pen approaches an acupoint, the warning light will flash, and the device will emit beeping sounds. The digital display will show a numerical value; a larger value and more rapid sound indicate closer proximity to the acupoint.
- Treatment: Once an acupoint is located (indicated by the strongest signal), press the pen tip firmly onto the acupoint and then press the 'Treatment' button to initiate the pulse massage.
- Using the Conductive Rod: If you experience numbness in your hands during treatment, insert the conductive rod into its designated port, hold the rod with your free hand, and then proceed with treatment. This helps to improve conductivity.



Tip for Acupoint Searching: Due to variations in human body impedance, skin dryness, and humidity, the sensitivity of acupoint searching may vary. If you experience no buzzing or continuous buzzing, refer to acupoint maps for physical therapy to guide your search.

8. User Tips
- Always start with the lowest intensity setting and gradually increase to a comfortable level.
- Ensure your skin is clean and moisturized for better conductivity and acupoint detection.
- For enhanced sensation and conductivity, consider using a small amount of conductive gel on the skin where you are applying the pen.
- Practice on a less sensitive area of your body first to get accustomed to the sensation.
- Regular use can help maintain the benefits of acupoint stimulation.
9. Maintenance
9.1 Cleaning
After each use, wipe the pen body and probes with a soft, dry cloth. For probes, you may use a slightly damp cloth with mild soap, then dry thoroughly. Do not use abrasive cleaners or immerse the device in water.
9.2 Storage
Store the acupuncture pen and its accessories in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it in its original packaging or a protective case to prevent damage.
10. Troubleshooting

|---|---|---|
| Device does not turn on or has no power. | Low battery or device is off. | Ensure the device is charged. Check the power switch. |
| No sensation or weak sensation during treatment. | Intensity/sensitivity too low, improper grip, dry skin. | Increase intensity and sensitivity settings. Ensure your thumb is firmly on the metal conduction area. Moisturize skin or use conductive gel. |
