2. Setup
Before first use, ensure all components are securely assembled for optimal performance.
- Ear Tip Adjustment: The ear tips should fit snugly into your ear canals. Rotate the headset so the ear tubes point forward, aligning with your ear canals. This ensures optimal sound transmission and comfort.
- Chestpiece Orientation: The Classic III features a dual-sided chestpiece. To activate either the adult or pediatric side, rotate the stem until the desired side is open. A slight click indicates proper engagement.

3. Operating Instructions
The Littmann Classic III Stethoscope is designed for effective auscultation across various patient types and clinical needs.
- Adult Diaphragm Use: Use the larger side of the chestpiece for adult patients. Apply light pressure to hear low-frequency sounds, and firm pressure to hear high-frequency sounds.
- Pediatric Diaphragm Use: The smaller side is ideal for pediatric patients or for auscultating smaller areas. This side can also be converted into a traditional open bell by removing the single-piece diaphragm and replacing it with a non-chill bell sleeve (sold separately).
- Auscultation Technique: Place the chestpiece firmly on the patient's skin. Listen for heart, lung, and bowel sounds. The stethoscope is engineered to help detect normal and abnormal sounds and rhythms, even at lower frequencies (below 120Hz) more reliably than some comparable stethoscopes.
- Clinical Environment: This stethoscope is particularly useful in non-critical care settings such as medical offices, general wards, OB/GYN clinics, ambulatory clinics, or urgent care facilities.

4. Maintenance and Care
Proper care and maintenance are essential to ensure the longevity and optimal performance of your stethoscope.
- Cleaning: Clean the stethoscope regularly with a 70% isopropyl alcohol solution or a disposable wipe. Do not immerse the stethoscope in any liquid.
- Disinfection: For high-level disinfection, follow your institution's established protocols for medical devices.
- Storage: Store your stethoscope away from extreme heat, cold, solvents, and oils. Avoid sharp objects that could puncture the tubing.
- Ear Tips: Remove ear tips periodically for thorough cleaning of the ear tubes. Ensure they are securely reattached before each use.

5. Troubleshooting
If you experience issues with your stethoscope, consider the following common solutions:
- Poor Sound Quality:
- Check ear tip fit: Ensure ear tips are securely attached and correctly oriented towards your ear canals.
- Clear tubing: Inspect the tubing for any blockages or cracks.
- Chestpiece orientation: Confirm the correct side of the dual-sided chestpiece is open. Rotate the stem 180 degrees if necessary.
- Diaphragm integrity: Check the diaphragm for cracks, tears, or loose fit.
- Loose Parts: Ensure all components, including the ear tips and chestpiece diaphragm, are firmly attached.
- Environmental Noise: Minimize ambient noise during auscultation for clearer sound perception.
