Instructions for Use

Changing Frequencies Using the Tunable Diaphragm

Your Littmann Select 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.

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.

Low frequencies: To listen to low frequency sounds (traditional bell mode) use very light skin contact.

High frequencies: To listen to higher frequency sounds (traditional diaphragm mode), press firmly on the chestpiece.

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.

This stethoscope utilizes a unique design for 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.

To listen to low and high frequency sounds without removing and repositioning the chestpiece simply alternate between light and firm pressure on the chestpiece.

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 Tunable Diaphragm

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.

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 diaphragm to slip into position.

General Use and Maintenance

• Avoid extreme heat, cold, solvents, and oils.

• The entire stethoscope can be wiped clean with alcohol or soapy water.

Insert the flexible edge of the diaphragm into the groove of the rim. This is best accomplished by starting with the rim positioned above the legible side of the diaphragm.

Visually examine the ring to ensure that the flexible edge is smoothly engaged inside the rim. If necessary, flex the assembly by pinching the outer rim edge

• Eartips can be removed from the eartubes for thorough cleaning.

NOTE: Do not immerse your stethoscope in any liquid or subject it to steam sterilization. If disinfection is required, the stethoscope may be wiped with a 70% isopropyl alcohol solution.
