[Note] When you first remove the breathalyzer from its packaging or leave it unused for a long time, a large amount of gas and other impurities may accumulate on the sensor. In this case, you need to preheat the breathalyzer by repeatedly pressing the power button. Because it takes approximately 20 minutes for alcohol to be absorbed from the digestive system into the blood, if you test immediately after drinking alcohol, the test result will only reflect the alcohol concentration in your mouth, not your blood. We recommend taking the test 20 minutes after drinking. To charge, you must use the charging cable included with the product. Alcohol tester
