- Power On: Press the 'ON/OFF' button on the control panel to turn on the device. The LCD display will illuminate.
- Select Mode/Intensity: Use the '+' and '-' buttons to adjust the intensity level and treatment time as displayed on the LCD. Refer to your healthcare professional's recommendations for appropriate settings.
- Apply Probe: Gently place the ultrasound probe flat against the skin in the treatment area, ensuring full contact with the coupling gel.
- Begin Treatment: The device will start emitting ultrasonic waves. Move the probe slowly and continuously in small circular motions over the treatment area. Do not hold the probe stationary in one spot.
- Monitor Time: Keep track of the treatment duration. Do not exceed 15 minutes per treatment area per session.
4.3 Ending Treatment:
- Power Off: After the desired treatment time, press the 'ON/OFF' button to turn off the device.
- Clean Up: Wipe any remaining coupling gel from the probe and the treated skin area using a soft cloth or tissue.
- Store Device: Disconnect the power cable and store the device and probe in a clean, dry place.
