Warning from ACE
Even if the device indicates an alcohol level in the „safe"
range, this does not mean that you can safely drive a vehicle
or carry out other activities that could be dangerous under
the influence of alcohol after consuming alcohol.
Switching the measuring units
After a test has been carried out, the breathalyzer displays
the result in per mille as standard. However, by briefly pres-
sing the power button, you can switch between different
measurement units, including BAC (blood alcohol concen-
tration in %) and mg/L (milligrams of alcohol per liter of bre-
ath). This allows you to display the measurement results in
the unit that suits you best or that is common in your region.
