1. Insert the battery, pull out the folding mouth piece
2. Press the green power switch , a beep sound indicates and an LED dot in the left hand of the 2 digit display flashes to indicate the sensor is operating the purifying warm up cycled.
3. Wait for the READY beep sound and the LED dot to stop flashing. Immediately place your lips, sealing the mouthpiece and blow / exhale for approx 5 seconds until it the tester beeps twice . A continuous beep tone during the exhale indicates the tester is receiving a alcohol breath sample. The tester will automatically turn off if no air pressure is detected within 15 seconds.

HOW TO USE
