Optimal Use of the ds32a Stethoscope

• Instructions - The ds32a Stethoscope is designed to be very easy-to-use. However, taking the time to read the User’s Manual will greatly facilitate the effective and optimal use of the ds32a. These instructions provide valuable tips that are well worth knowing, to get the most out of the ds32a.

• Sound Levels - Adjust the Volume to a comfortable level. The ds32a Stethoscope has powerful amplification. Maximum volume is not necessary in most situations. Experiment to identify optimal settings and personal preferences.

• ANR2 Ambient Noise Rejection - The ds32a Stethoscope has second generation Ambient Noise Rejection (ANR2), enhancing the noise rejection capability of EmD technology. The noise rejection function can be activated or deactivated, providing you with complete control over signal processing functions. Experiment with each setting to select the best for each situation.

• Diaphragm Pressure and skin contact - The ds32a Probe uses Electromagnetic Diaphragm (EmD) technology which is pressure-sensitive. Sound characteristics change as the Probe is applied with greater pressure to the patient. Simply apply the Probe to the patient as with a conventional stethoscope, and make subtle changes in pressure, listening for desired sound. Lighter pressure is usually optimal. Increase pressure gradually to increase sensitivity and volume. With significantly increased pressure, low frequencies will suddenly be attenuated and lung sounds will be audible over heart sounds. Apply steady diaphragm pressure for best results. The ds32a’s EmD diaphragm operates best when in direct skin contact with the patient.

• Maintaining Performance - Your ds32a Stethoscope is a robust instrument designed to provide continued peak performance. If your ds32a is not meeting your highest expectations, please contact us so that we can help you obtain and maintain the performance level for which it is designed.
