the tip of the probe until it is fully seated. The three probe tubes should be nearly flush with the top
surface of the eartip.
Inserting the Combo Probe
Insert the probe tip securely into the ear canal with a twisting motion. Pull the pinna up and back for
adults, and down and back for children to straighten the ear canal. The probe tip should sit firmly
within the ear canal without being held. If a leak occurs, a different size eartip may be needed.
