Amplify , Volume Control, Mute

To alternate between Amplify and Acoustic modes, click the key.

To Mute sound, hold the key:















Amplify mode - Augmented sound, Volume is ADJUSTABLE - BLUE LED On. Volume Control located behind the Control Panel near the Power key.

Acoustic mode - Volume is PRE-SET - BLUE LED Off. Provides pre-set Volume similar to a conventional acoustic stethoscope. The ds32a still performs electronic signal processing in Acoustic mode, and you will notice the resulting clarity of signals in Acoustic mode. However, the sound characteristics in this mode are set to be similar to an acoustic stethoscope, so that users can compare standard and boosted sounds, such as during the grading of murmurs. This provides the “best of both worlds”, with access to both acoustic and boosted sound characteristics in one device.

Mute function - Push and Hold the Amplify key to Mute sound. When potentially loud sounds could occur, keep a finger on the Amplify key, ready to Mute when necessary. Example situations might be when listening to a carotid bruit and the patient might begin to speak, or when listening to pediatric patients.
