Solution
DPA Cup is Not Rotating
Outside of the mouth:
1. Ensure the outer sheath and the DPA are snapped together securely.
2. Ensure that the cordless handpiece motor component and the outer
sheath are snapped together securely.
3. Verify the cordless handpiece is powered up and properly charged. If the
indicator lights do not illuminate, place the cordless handpiece in the
charging station for a minimum of 5 seconds, and then remove it to use.
4. Ensure the DPA is not damaged by removing the DPA and spinning the cup
between your fingers. The cup should spin freely.
5. Ensure that the outer sheath is not damaged by removing the cordless
handpiece motor component from the outer sheath, leaving the DPA
connected, and spinning the DPA cup between your fingers. The cup
should spin freely.
In the mouth:
1. Excessive force is being applied to the polishing surface, reducing the DPA
rotation. Use a lighter force and follow standard prophylaxis procedures.
