How does it work?
POWER ON: Press the power button to switch on the unit. The unit initiates sensor warm-up and auto-cleansing process. Timer counts down from 99 to 0.
READY: Wait until “Rdy” (Ready) appears with a single “beep” to indicate that the unit is ready to use.
BLOWING: Blow STEADILY into the mouthpiece or the straw for 5 seconds UNTIL a “beep” sounds to signal completion of the test.
The unit analyses the sample and shows the measured Blood Alcohol Content (BAC) on the LCD display. Depending on the version of your product, BAC value will be displayed in ‰ BAC / % BAC / mg/L
System message “Sn” (System Not Read), what does this mean?
This means the system needs another warm up/auto-cleansing loop.
