Instructions for Use Chestpiece

On 3M™ Littmann® Classic II Infant or Pediatric stethoscopes with traditional combination Chestpiece, you select either the diaphragm or open bell side by holding the chestpiece stem in one hand and rotating  the chestpiece with the other hand until a click is felt.
Low frequencies: Use light contact on the bell side to hear low frequency sounds.

High frequencies: Turn the chest piece over, index to the opposite side and use firm pressure to hear high-frequency sounds.

Headset Adjustment

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

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

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

For maximum acoustic performance, comfortable patented 3M™ Littmann® Snap Tight Soft-Sealing Ear tips are provided with your stethoscope.
This stethoscope utilizes a unique design for attaching the ear tip to the earthbag. The ear tips are pushed on to the end of the earthbag and snapped firmly into place. To remove, pull firmly on the ear tip.

Removing the Diaphragm and Cleaning the Chestpiece

With the diaphragm side up, push the rim at one point with both thumbs and roll the rim off the edge of the Chestpiece.
Remove the diaphragm from the rim and clean parts in soapy water or wipe with alcohol.
Wipe Chestpiece surfaces with alcohol or soapy water. Dry all parts and surfaces thoroughly before reassembly.

Replacement of the Diaphragm

Place diaphragm on Chestpiece surface. Totally engage diaphragm and Chestpiece edge in groove of rim at one point, and hold in place with thumb. While maintaining rim engagement at one point, roll rim over the entire outer edge. Make sure diaphragm is completely contained in groove of the rim.

General Use and Maintenance

• Avoid extreme heat, cold, solvents, and oils.
• The entire stethoscope can be wiped clean with alcohol or soapy water.
• Ear tips can be removed from the earbobs 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.
