Headset Adjustment
Your new Harvey Stethoscopes are designed to give you the
maximum ability to adjust for your personal comfort and acoustic fit.
A. Select the correct size and texture eartip. For
maximum acoustic seal, two sizes of “soft” and
“hard” eartips are provided. Choose the size
which best seals off your outer ear canal and
feels the most comfortable. As a rule the larger
size is best for the majority.
C. Make sure that the
binaural tubes are
pointed slightly
forward going into
the ear canal. B. To adjust the
angle of the
binaurals, hold
the spring in one
hand and rotate
each binaural to
the correct angle.
