A. Installation of the stethoscope
The stethoscope is designed to fit the ear canal angle of the patented ergonomic ear tubes and sinuses. It fits comfortably in the ear canal without fatigue or discomfort. Before putting on the ear tubes, pull the ear tubes of the stethoscope outward; the metal ear tubes should be tilted forward to put the ear tubes into your outer ear canal so that the sinus closes tightly with your ear canal; everyone's ear canal is different in size, so you can choose the right size sinus.
If you wear the device correctly, but the tightness of the sinus and the ear canal is poor, and the auscultation effect is not good, please pull the ear tube outward to adjust its elasticity. When the sinus and ear canal are not in close contact, incorrect wearing methods can lead to poor auscultation. For example, when the ear tubes are worn backwards, they will be completely inaudible.
