Did you check the opening indicator dot on the stem of the chestpiece?
Is the stethoscope put in your ears correctly?
Did you locate the correct heart’ s position?
Check the Dual Head Chestpiece
FriCARE dual head chestpiece enables you to switch the active sound chan-
nel from the diaphragm side to the bell side or vice versa, which is flexible to
listen to high and low frequency sound for auscultating adult patients.
The BLACK indicator dot (Fig.1) has been placed on the stem to facilitate
the identification of the active sound channel. If the diaphragm is open, the
bell will be closed, preventing sound from coming in through the bell, and
vice versa.
