If the test is conducted im-mediately after drinking, the test result will only reflect the al-cohol concentration in the mouth rather than the alcohol con-centration in the blood. As alcohol is absorbed, the test resultswill dramatically change.

【2】 Please do not directly wipe the device with chemicals orcorrosive solvents to prevent liquid from flowing into themouthpiece.

【3】 If the test is conducted with a low battery, there might bedeviation between the test result and the true value.
