How do I know what Contact Tip to use?
To determine which one is right, start with the least aggressive (factory installed Blue Contact Tip) and work your way up to the most aggressive Contact Tip (Violet). If you get enough blood with Blue and it doesn’t hurt, stop there – you’ve found your Contact Tip for that location. If you feel no pain, but not enough blood after holding the Activation Button for more than 5 seconds, then move up to the next contact tip color (Yellow). Repeat this process until you find the contact tip that you get blood with relatively no pain.
You should never have to replace your Contact Tips unless you lose them!
