Do you have a question about the 3M Littmann Classic III and is the answer not in the manual?
The stethoscope headset is angled for optimal ear canal anatomy fit. Eartips should point forward when inserting.
Modify headset tension by pulling eartubes apart (reduce) or squeezing together (increase) for a comfortable, secure fit.
The chestpiece has two sides; only one is active at a time, indicated by a stem mark. Rotate to switch sides.
Use light pressure for low frequencies and firm pressure for high frequencies to emphasize specific sounds.
The small chestpiece side can be converted to a traditional open bell by replacing the diaphragm with a nonchill sleeve.
Guidelines for cleaning with alcohol, soap/water, or bleach solutions, and proper storage to maintain the stethoscope.
Information on product registration, five-year warranty coverage, and contact details for service and repair inquiries.
