Tips for using your Stethoscope properly 1.Align the headsetBefore placing the eartips in your ears, make sure they point forward, away from you. (Figure A) This ensures that the eartubes will align with your ear canals for comfort and maximum sound transmission. Holding the headset in front of you with one eartube in each hand, pull the headset open and place the eartips into your ears. (Figure B)If the fit isn't comfortable, or acoustic performance is lacking, adjust the headset tension. All our stethoscopes feature adjustable headsets. Gently squeeze the eartubes together to increase headset tension; pull them apart to decrease tension.Wearing the headset improperly, (eartips pointing backwards, for example, as in Figure C) can result in a poor acoustic seal and, in some cases, complete sound blockage.  A. Proper InsertionB. Correct Positioning C. Incorrect Positioning 2.Rotate to the correct sideWhen using a double-sided stethoscope, you need to open (or index) the side you want to use-bell or diaphragm-by rotating the chestpiece. If the diaphragm is open, the bell will be closed, preventing sound from coming in through the bell, and vice versa.
