Instructions for using the Portable Breathalyzer:
- The first time you use the Portable Breathalyzer or if you haven't used it in a while, you'll need to let it warm up a few times before it's ready to use. This is due to oxidation that naturally occurs on the sensor inside the device.
- Let the Portable Breathalyzer warm up for 10 seconds.
- After the Portable Breathalyzer warms up, it will instruct you to blow. Blow into the mouthpiece with moderate pressure for 3-5 seconds.
- After testing, the BAC will appear on the screen and, if in the danger zone, the Portable Breathalyzer will beep.
- Make responsible decisions!
