When using the digital breathalyzer it is very important to wait 20 minutes after your last beverage and food consumption. Why? Because the alcohol residue in your mouth and on your lips will not only give you an inaccurate reading, but it can also damage the sensor. (I know, because the first Slim device I was sent stopped working because someone hadn't waited the 20 minutes.)

If you can't wait the 20 minutes, Q3 Innovations recommends that you rinse your mouth out with water before testing.

It is also essential that you do not test the breathalyzer in bars or where there is heavy drinking and smoking going on. Be outside or in your car.

How to Test the AlcoHAWK Slim:

1. After 20 minutes, turn the device on. 

2. Wait 60 seconds (you'll see the device counting down).

3. Once the blinking red light appears, you'll hear a single beep.

4. Take a deep breath. Start blowing into the mouthpiece for approximately 5 seconds or until you hear the beep. 

5. Your reading is then displayed in 2 decimal places.

If others are going to use the device, make sure you replace the mouthpiece with another cover. Allow 2 minutes for subsequent testing.

How to Test the AlcoHAWK ABI:

1. After 20 minutes, turn the device on. 

2. The detector will start to count down from 200 on the display. 

3. Once the green light appears, you'll hear a single beep.

4. Take a deep breath. Start blowing into the mouthpiece for approximately 5 seconds or until you hear the beep. 

5. Your reading is then displayed in 2 decimal places.

Again, if others are going to use the device, make sure you replace the mouthpiece with another cover. Allow 2 minutes for subsequent testing.
