• Lungs: Recordings performed on 4 positions on the chest and back respectively to listen to respiratory sounds.
• Wide: Recordings performed positioning the device freely to listen to heart and lung sounds.

Preparing for a Measurement

Make sure you follow these guidelines before taking a measurement:

1. Ensure you are seated in a calm and relaxed position with your feet flat on the floor.
2. If you are taking a measurement on someone else, you should both be quiet and keep still.
3. Do not move your fingers on the device during the recording, this can cause friction noises in the recording.
4. Wait at least 10 minutes after waking up or working out before taking your measurement.
5. Ensure you are at least 1.5 feet from any power outlets or large electronic devices (such as computers, tvs, etc).
6. Ensure the area you are in is quiet and you cannot hear any ambient noise.
7. Use headphones, plugged in the provided USB-C to headphone jack adapter, to listen to the recording live and ensure optimal audio quality.
8. Wear at most one thin layer of clothing for the stethoscope recordings.
   Note: Direct skin contact will ensure the most accurate recordings.
9. Ensure you don’t move your hand or body during the 15 second measurement.
10. Ensure that the stethoscope is in contact with your body during the measurement and that it is perfectly still on your skin.
11. When taking a heart recording, hold your breath to ensure your recording is as clear as possible.

How to take a measurement

To take a measurement, follow these steps:

1. Turn on the device by pressing the central button.
2. Choose your user profile.
   Note: For your first measurement a tutorial screen will appear to show you the stethoscope sensor location. If you see this, use the buttons to follow along or skip.
3. Navigate to the Stethoscope Icon:
   
4. Select either Heart, Lung, or Wide (free position) mode on the device screen.
5. Select the position you want to record.
6. Place the stethoscope (flat grey end of the BeamO) in the precise point indicated on the device screen.
7. If you have headphones plugged in to the BeamO, you can adjust the volume, even hearing a preview of the sound to make sure it sounds audible before recording.
   
8. When you are ready, press the central button to START recording. Each recording lasts 15 seconds.
9. After each recording, you’ll be prompted to record in the next position.

Important: The recordings made by the stethoscope will not provide any analysis on the device or in the app. These recordings should be evaluated by a medical professional.

Heart Positioning	Lung Positioning

Notes:

• You can modify the order of the recording positions by selecting another position on the device. You may also end the exam before completing recordings in all indicated positions.
• You can listen to the heart and lung sounds during the recording by connecting your headphones to the provided adapter and to the USB C port on the device. To adjust the volume,  navigate down to the volume bar and click left or right with the cursor before starting the recording.
• However, BeamO cannot be used with USB-C headphones. Headphones must be analog (3.5mm jack) and use the USB-C adapter.
