الإعداد والتجميع
Adjusting Headset Tension
The headset tension can be adjusted for head size and comfort. To decrease tension, pull the eartubes apart. To increase tension, squeeze the eartubes together. Ensure the eartips are securely snapped onto the eartubes.
استبدال سماعة الأذن
For safety, Littmann soft-sealing eartips snap firmly onto the eartubes and require significant effort to remove. To replace, firmly grasp the eartube and twist the eartip off. To attach new eartips, push them firmly onto the eartube until they snap into place.
عملية
Using the Tunable Diaphragm
The Classic III stethoscope features a two-sided chestpiece with tunable diaphragms on both the adult and pediatric sides. This technology allows you to hear different frequency sounds by simply adjusting the pressure applied to the chestpiece.
- Low-Frequency Sounds: Apply light pressure to the chestpiece to hear low-frequency sounds (e.g., Korotkoff sounds, Mitral Stenosis, S3 and S4 Gallops).
- High-Frequency Sounds: Apply firm pressure to the chestpiece to hear higher-frequency sounds.

Switching Between Adult and Pediatric Sides
The chestpiece can be rotated to select either the adult or pediatric side. The adult side is 1.7 inches (4.3 cm) and the pediatric side is 1.4 inches (3.4 cm). The pediatric side can also be converted into a traditional open bell by removing the tunable diaphragm and replacing it with the non-chill bell sleeve (included).
