Using Your 3M Littmann Master Cardiology Stethoscope with patented tunable diaphragm.

Littmann stethoscope's patented tunable diaphragm technology offers time-saving convenience, versatility and enhanced acoustics. Unlike the traditional bell/diaphragm design that requires turning the chestpiece to switch between low and high frequency sounds, a Littmann stethoscope tunable diaphragm alternates between bell and diaphragm modes with a simple pressure change on the chestpiece. Use light contact to hear low frequency sounds. Press firmly for high frequency sounds.
