Stethoscope User Manual
Congratulations on the purchase of your new
3M™ Littmann
Classic III™ Stethoscope.
®
The Littmann Classic III stethoscope provides high
acoustic sensitivity combined with exceptional
versatility. Its innovative design offers a tunable,
single-piece diaphragm on each side of the
chestpiece; the large side can be used for adult
patients, while the small side is especially useful for
pediatric assessment. Plus, the pediatric side of the
chestpiece can be converted to a traditional bell by
replacing the tunable diaphragm with the nonchill
bell sleeve included with your purchase. For more
