If pairing for the Littmann 3200 for the first time, users will need to follow the steps detailed in the How to Connect a Littmann screen. Once the Littmann is identified in the Connection screen they will need to click the blue Pair button:
Windows pop-ups and 3200 PIN screen

PIN screen on Littmann 3200
Along with the Windows “Add a device” pop-up, the screen on the Littmann 3200 will likely display a PIN screen during the pairing process. The Eko app does not require entry of this PIN. The Eko Windows application will identify the Littmann 3200 by it’s serial number, the last four digits of which are equivalent to the PIN. The serial number is also visible on the Littmann 3200, users may want to document the PIN for easier identification when connecting the device with the Eko application.
Connection Screen 4:
Once the Littmann 3200 is successfully paired with the Eko Windows app users should see the application’s interface change to show the tracings of the audio data being transmitted from the Littmann 3200. Users can now initiate a Live Stream, visualize waveforms, and disconnect the Littmann 3200 directly from the Eko app.
Subsequent use of the Littmann 3200
After the initial Bluetooth pairing process is completed, users can connect the Littmann 3200 by turning the stethoscope On and clicking Connect Device.

- Press 'M' on the Littmann 3200
- Select Connect
