[Diagnostic Devices](https://support.omply.com/en/diagnostic-devices?hsLang=en) November 5, 2026 # Digital stethoscope: guide and troubleshooting With the digital stethoscope, your doctor listens to your heart and lung sounds during a remote appointment. The device is the Mintti Smartho-D2. It connects to your phone over Bluetooth and runs on a rechargeable battery. ### How to use the stethoscope 1. Press and hold the power button for a few seconds. 2. The device connects to your phone and the Omply app automatically. On the Devices tab, check that Stethoscope shows Active. 3. Grip the black upper part of the device firmly with all five fingers. 4. Press the blue listening end firmly against your bare skin at the spot your doctor tells you. Keep your fingers still while the doctor listens. 5. Stay still and breathe the way your doctor asks. Your doctor tells you when to move to the next spot. 6. When you're done, turn off the device by pressing the power button until a shutdown message appears on the screen. If you like, you can plug your own headphones into the AUX connector and hear the sounds yourself. ### If something goes wrong - **The device doesn't respond to the power button.** The battery is probably empty. Place the device on the charging base and connect the included USB cable to a 5 V charger or a computer's USB port. Don't use the stethoscope while it's charging. - **The battery icon on the screen is empty.** Charge the device before your appointment. A full charge takes about four hours. - **There's no charging icon and the device has turned off on the charger.** The battery is full, so there's nothing you need to do. - **The app shows Device not detected.** Check that the stethoscope is on, Bluetooth is on and the device is close to your phone. If it still won't connect, see [My device won't connect](https://support.omply.com/en/my-device-wont-connect.-how-can-i-fix-it?hsLang=en). - **Your doctor hears a rubbing noise.** Keep the listening end still on bare skin. Don't move your fingers or talk while your doctor listens. ### Instruction video and user manual - [Watch the instruction video (in Finnish)](https://support.omply.com/en/device-instruction-videos-in-finnish?hsLang=en#h_01KPN6QYXZFEH28AD3ZCAX38FN) - [Quick guide (PDF)](https://support.omply.com/hubfs/User%20manuals/User%20Guide_Digital%20Stethoscope.pdf?hsLang=en) - [Manufacturer's user manual (PDF)](https://support.omply.com/hubfs/Stethoscope-Manual.pdf?hsLang=en) ### Related articles - [My device won't connect.
