- Power On: Flip the host switch on the rear of the unit to the 'ON' position.
5. Operating Instructions
Follow these steps for an effective treatment:
- Cleanse Skin: Ensure the treatment area (face or body) is clean and dry before application.
- Apply Conductive Gel: Apply a generous layer of conductive gel to the area you intend to treat. The gel is essential for the RF waves to penetrate the skin effectively and for comfortable use. Reapply gel as needed to maintain smooth gliding of the probe.
- Select Intensity Level: Use the 'Gear button' on the main unit to select your desired intensity level (1-3). Start with a lower level and gradually increase as your skin tolerates it.
- Set Treatment Time: Use the 'Time button' to set the desired treatment duration, typically 10-15 minutes per area.
- Begin Treatment: Place the probe gently on the skin. Move the device in slow, circular motions, from bottom to top and from inside to outside. Do not hold the device in one spot for more than 2 seconds.
- Monitor Skin Temperature: The device features a safety system that automatically adjusts energy based on skin temperature. If you feel the device becoming too hot, it will automatically reduce the heat level. You can also manually reduce the intensity.
- Complete Treatment: Once the set time has elapsed, the device will stop. Turn off the device using the host switch.
- Cleanse After Use: Wipe off any remaining gel from your skin and the device.

6. Maintenance
- Cleaning: After each use, wipe the probe and the main unit with a soft, damp cloth. Do not use abrasive cleaners or immerse the device in water.
- Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the device is clean and dry before storing.
- Cable Care: Avoid bending or twisting the power cord and handle cable excessively to prevent damage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Power cord not connected; Host switch is off. | Ensure power cord is securely plugged in. Flip the host switch to 'ON'. |
| No heat or very little heat felt. | Insufficient conductive gel; Low intensity setting; Device safety system activated. | Apply more conductive gel. Increase the intensity level. Move the device continuously to allow the safety system to reset. |
| Skin feels too hot. | Intensity level too high; Device held stationary. | Reduce the intensity level. Ensure continuous movement of the probe. |
| No visible results after initial use. | Results require consistent use over time. | Consistent use is key. Visible improvements typically appear after 2-4 weeks for facial areas and 3-5 months for body areas with regular application. |
