If you're a customer who purchased your own Eko device, go to the Eko Help Center.
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 is available as part of a fully-assembled 3M™ Littmann® CORE Digital Stethoscope.

Turn on and turn off the CORE
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 use your phone's volume adjustment to change the volume of audio coming through the headphones.
Note
Changing the volume on the 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 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.
