Drinking alcohol in ANY amount may impair the ability to drive. There is no “safe” level
of alcohol intake before driving. Don’t drink and drive.
Note: The maximum reading the device can show is 0.40%. A true BAC of 0.40% or
above may result in the onset of coma or even death by respiratory arrest. A reading
of 0.40% may indicate an acutely dangerous condition, but may also indicate a
sampling error (such as liquid alcohol blown into the device). Please carefully read
the
Warnings
section of this manual before operating the device.
