The Eko CORE is an electronic stethoscope that enables amplification, filtering, and transmission of auscultation sound data (heart, lungs, bowel, arteries, and veins). The CORE is a small attachment that is located between the tubing and chestpiece of a stethoscope.
The Eko CORE digital attachment is a standalone attachment that a clinician can attach to any stethoscope.

Here’s how to assemble your CORE with your stethoscope.
Follow our three-step process to attach the CORE to your analog stethoscope.
Remove the chestpiece from your analog stethoscope. Grip the chestpiece with one hand and the tubing in the other and pull them apart. This may require some force.
-
Select either the standard or pediatric size tubing connector and insert your chestpiece into the tubing. If the standard tubing connector feels loose on the chestpiece, please try the pediatric tubing connector instead.
-
Carefully screw in the chestpiece and tubing connector into the end of the CORE that’s closest to the power toggle. Please make sure the threads are aligned when you are screwing it in otherwise it may be prone to cross-threading.
-
Select the corresponding barb (either pediatric or regular) and carefully screw it into the other end of the CORE. Make sure the threads are aligned when you are screwing it in as it may be prone to cross-threading.
-
On the other end of the CORE, select the corresponding barb (either pediatric or regular) and screw it into the base of the CORE. Make sure the threads are aligned when you are screwing it in as it may be prone to cross-threading.
-
Connect the barb to the stethoscope tubing.
Here’s how it works:
Depress the power slider to move the switch from the OFF to the ON position.
“ON” is when the toggle is flushed with the surface of the volume buttons. A white blinking light indicates that the CORE has been turned ON. You can now hear amplified sounds through the stethoscope. The CORE is also ready to pair with a mobile device and transmit digitized sounds.
OFF is when the toggle is protruding from the surface of the volume buttons. The white light disappears and you can now hear unamplified sounds through the stethoscope earpieces.
The CORE has a five minute standby mode to conserve battery life. The white light disappears when the CORE goes into standby mode and the toggle remains flat with the surface of the volume buttons (the “ON” position). To turn the CORE back on, push the toggle to OFF and then the ON position. The white light appears to indicate the device is on.
The CORE’s sound level can be amplified in seven increments up to 40X amplification over an unamplified, acoustic stethoscope when listening with the stethoscope earpieces. Change the volume level by clicking the plus (+) and minus (-) volume buttons on the side of CORE.
If you're using headphones to listen to the sounds through your mobile device, you’ll need to adjust your phone’s volume to change the CORE’s volume.
Note
Changing the volume on the CORE does not affect the volume of a recording on the Eko App running on your mobile device. The recording volume must be adjusted in the app or on the phone itself.
When the yellow light starts blinking on the CORE, the battery in the CORE needs to be charged.
Insert the included micro USB cable into the USB port on the CORE and plug the other (USB-A) end into a UL-certified USB wall charger (max 5 volts). The LED turns solid yellow, signifying that it's charging.
The LED changes to solid green when the device is fully charged.
To fully charge the battery, it should take about 2.5 hours. When fully charged, the CORE should last for about 8 hours of continuous use. We recommend turning the CORE off between each use to maximize battery life.
Note
The CORE will not turn on or connect to the Eko App or Dashboard while it’s plugged in and charging.
The stethoscope and CORE should be cleaned between each patient's use. All cleaning instructions pertaining to the original stethoscope apply.
Under normal conditions it's unnecessary to remove the CORE from the stethoscope tubing for cleaning. All external parts of the hardware can be cleaned with 70% isopropyl alcohol wipes.
Warning
DO NOT immerse the device in any liquid or subject it to any high-pressure/autoclave sterilization processes.
If it becomes necessary to remove the CORE digital attachment from the rest of the stethoscope, pull the stethoscope tubing off of the metal stem of the attachment on both ends of the attachment. You may need to pull firmly to detach the components. Wipe all parts of the stethoscope clean with 70% isopropyl alcohol wipes including the CORE’s surface, stethoscope tubing, tubing connector, and chestpiece. Reassemble the stethoscope by reinserting the metal stems into the stethoscope tubing as before.
Follow the steps below to get the best quality auscultation when using your CORE and stethoscope earpieces:
-
If possible, perform auscultation in a quiet environment. While the CORE has active noise cancellation, some environmental noise may still be audible during auscultation.
-
Use the bell to best listen to low frequency sounds like heart sounds. Use the diaphragm to best listen to high frequency sounds like lung sounds.
-
Hold the diaphragm firmly against the chest. Avoid any motion. Beware of pressing too tightly, as that can muffle sounds.
