👋 Steps to Use the Probe

1. Hold Like a Pen
   Use three fingers: thumb, index, and middle. Your wrist must be relaxed.
   
   

2. Apply Gel
   Put a good amount of gel on the patient’s skin or directly on the probe.
   
   

3. Place the Probe on the Skin
   Touch the skin gently and steadily.
   
   

4. Move Slowly
   Move side to side, up and down, or rotate as needed—watch the image on the screen.
   
   

5. Adjust Angle if Needed
   Tilt the probe to improve the view (this is called “angling”).
