How do I give a breath sample on my own, without the guided breath test in the app?

1. Make sure the mouthpiece is inserted into your breath sensor. 
2. Press and hold the main button until you hear a beep, and the screen reads "Take a deep breath..."
3. Release the button.
4. Take a deep breath in and hold it.
5. Continue to hold your breath for a minimum of 8 seconds. When you hear 3 beeps, from the sensor, prepare to blow into it.
6. After the third beep, gently blow into the breath sensor. Blow for 12 seconds or until you breathe all the way out.
