3. Operating Instructions
A> Battery Installation:
A-1 Remove the cover of battery compartment at the back of device.
A-2 Insert 2 “AAA” alkaline batteries according to correct polarity, then close battery compartment cover.
B> Start:Press power button at least 2 seconds, with a short beep tone, backlit lights lit and display 0018 (or other value) that represents the tested times so far, press button less 3 seconds to display the test value of last time.
C> Blow:Display the moving value “0” and “blow”, please blow continuously for 3 seconds via mouthpiece. The device can automatically detect along with beep sounds when blowing, and display “----” that shows data analysis is in processing after blowing. It will automatically power off if no blowing action taken place in 2 minutes.
D> Result display:Several seconds later data analysis finished, the displayed value is the concentration of alcohol.
E> Re-measure: Press button again for the next test.
F> Power off:
F-1 After finishing the test or during the test, hold down the button at least 2 seconds to turn off the device.
F-2 If forgetting to turn off the device after finishing the test, the device will automatically turn off after 1 minute.
