Read instructions carefully before using and save for future reference.

General Safety: MDF stethoscope is exclusively designed as a non-invasive medical auscultation instrument to detect 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 angled anatomically for best fit, comfort and sound transmission. The headset should be worn with the eartips pointed away from you if it is held directly in front of you. The dual-head chestpiece contains diaphragm-side for detecting high frequency sounds and bell-side for detecting low frequency sounds. According to auscultation need, simply turn the full-rotational acoustic valve stem to select the proper chestpiece head. Hold the chestpiece firmly against the desired auscultation location on the patient's external thoracic region. Prior to each use, make sure all parts are securely fastened and properly connected.

General Cleaning & Care: Clean stethoscope thoroughly before each use. Use clean cotton cloth or swab and isopropyl alcohol solution to cleanse all soiled parts. Avoid prolong exposure of acoustic tubing to excessive heat, cold, solvents, moisture and oils/lipids (secreted by human skin).

Our commitment to high-quality instruments is backed by our two-year performance guarantee.
