Instructions for Use Chestpiece

On Littmann stethoscopes with traditional combination chestpieces, it is necessary to open the side of the chestpiece being used. This is accomplished by holding the chestpiece stem in one hand and rotating the chestpiece with the other hand until a click is felt.

Changing Frequencies Using the Tunable Diaphragm

Your Littmann Classic II S.E. Stethoscope is equipped with a patented tunable diaphragm that enables you to listen to both low and high frequency sounds without turning over the chestpiece.

Headset Adjustment

Your Littmann stethoscope is designed to provide a comfortable, acoustically sealed ear fit. Notice that the eartubes are set to accommodate the typical anatomy of the ear canal. The eartips should point in a forward direction as you insert them into your ear canals.

To reduce spring tension in the headset, hold each eartube at the bend near the eartip and gradually pull apart until fully extended.

To increase spring tension, grasp the headset with one hand where the eartubes enter the tubing and squeeze until the tubing on one eartube touches the other. Repeat as necessary.

For maximum acoustic performance, comfortable patented 3M™ Littmann® Soft-sealing Eartips are provided with your stethoscope. This stethoscope utilizes a unique design for

Low frequencies: To listen to low frequency sounds, (traditional bell mode) you can use either the open bell or tunable diaphragm using very light skin contact.

attaching the eartip to the eartube. The eartips are

pushed on to the end of the eartube and snapped firmly into place. To remove, pull firmly on the eartip.

Removing the Diaphragm and Cleaning the Chestpiece

With the diaphragm side up, grasp the rim with the thumbs and index fingers of both hands and roll the rim off the edge of the chestpiece. Remove the diaphragm from the rim and clean the parts in soapy water or wipe with alcohol. Chestpiece surfaces can be wiped with alcohol or soapy water. Dry all parts and surfaces thoroughly before reassembly.

Assembly and Replacement of the TunableDiaphragm

Using your fingertip, apply a small amount of talcum powder to the inside surface of the flexible edge of the diaphragm. This will facilitate assembly and maintain smooth and quiet low/high frequency alternation.

Snap the diaphragm with your fingers to remove excess

talc.

Visually examine the ring to ensure that the flexible edge is smoothly engaged inside the ■ IvCT/'' rim. If necessary, flex the ^V^LIX assembly by pinching the outer

rim edge between the thumb and fingers. Repeat this flexing procedure after rotating the assembly one quarter.

To attach the rim/diaphragm assembly to the chestpiece, engage the groove of the rim (with the diaphragm attached) around the chestpiece at one point and hold it in place with your thumbs.

Slowly roll the rim around and over the chestpiece edge using both thumbs, moving in opposite directions around the chestpiece.

Visually inspect the edge where the diaphragm engages the rim for uniform containment. Minor adjustments may be made by slightly pulling and rolling the rim away from the diaphragm, allowing the
