General Safety: This MDF® stethoscope is designed exclusively as a non-invasive medical auscultation instrument for the detection of heart and lung sounds on healthy skin around the external thoracic region. Due to its sound amplification function, it may cause damage to user’s ears if used other than its intended medical diagnostic purpose. Use only if you are a medical professional and do not leave stethoscope unattended around children.

General Usage: MDF® stethoscope headsets are anatomically adjustable for best fit, comfort, and sound transmission. A headset adjusted to a 15° forward angle is standard, and should be worn with the eartips pointed away from you if it is held directly in front of you.

Depending on the model, the stethoscope offers up to six different attachments for specific auscultation functions:

For chestpiece, acoustic tubing, and ComfortSeal™ eartips, use clean cotton cloth or swab and rubbing alcohol or isopropyl alcohol solution to cleanse all soiled parts. Avoid prolonged exposure of the acoustic tubing to excessive heat, cold, solvents, moisture, or oils/lipids (secreted by human skin).
