Acoustic Mode utilizes electronic signal processing to provide
pre-set sound characteristics similar to a conventional acoustic
stethoscope, but with enhanced signal quality.
Zoom Mode provides signal processing augmentation with
power boost and Adjustable Volume to “zoom in” on details.

NOTE POLARITY. Push springs to seat batteries properly. Align cover & close.
Hold Probe steady
to reduce artifact.
The EmD Diaphragm detects signals in the sub-sonic
frequency range, to reproduce quiet low-frequency heart
murmurs. Patient chest wall motion, or unsteady
examiner hand motion, can induce large-amplitude subsonic vibrations. This can overload the detector and
produce signal artifact or cutout. It is then helpful to hold
the Probe so that the fingers holding the Probe also touch
the patient chest wall (such as the left edge of the thumb
and the fingertips in the above figure.) The Probe and
chest wall then move in unison, with a consistent, light
diaphragm pressure.

Sync - Probe location influences detection as follows:
• Mitral/Apex - S1 usually detected over S2.
• Tricuspid
- S1 / S2 / Both possible.
• Other areas - S1 usually detected over S2.
See CD User’s Manual for details on the use of Sync.

Tips and Troubleshooting
Tips for Best Sound Quality
•Apply Probe with light, steady contact, not excessive pressure. (Step 5, See Over).
•The ds32 works best with direct skin contact. Avoid using through clothing.
•Experiment to find a preferred Volume level that optimizes clarity.
•Load the Reference CD into a computer and READ the User’s Manual.
The Manual contain USEFUL TIPS for obtaining best results.
Troubleshooting
• No Power: (a) Check batteries are inserted correctly. (Step 1, See Over).
(b) Batteries need replacing.
• No Sound: (a) Increase Volume setting.
(b) Check headphone fit (See Over).
• Unexpected interference sounds:
(a) Radio station or electromagnetic pickup: Change position/location.
(b) Continuous Buzzing: Diaphragm loose - tighten Diaphragm Ring.
(c) Other noises: Possible dust, lint or moisture inside Probe Turn off device. In dust-free environment, unscrew Diaphragm ring.
Wipe inside surface of diaphragm and sensor with an alcohol swab.
Do not touch brass sensor plate or diaphragm with fingers.
Allow to dry/evaporate naturally, then close unit.
• Problem unsolved? Contact Thinklabs. See Over for contact information.
