2. Operation Instruction

2.1. Slide down the battery compartment on the back side, insert 3pcs AAA 1.5V batteries inside according to battery polarity indication and close it.

2.2. Press the power button for 1S, after 1 beep sound, “ warm up “ will be displayed on LCD , after 20 second with 1 “beep“ sound, “ blow” will be displayed on LCD and start to countdown and inform for testing.

2.3. Blow directly to the mouthpiece, after 4 seconds with 1 ”beep” sound to inform to stop blowing and the test result will be displayed on LCD. 

2.4. Unit switch: On test result mode, press “power“ button to change the unit (% BAC-‰BAC -mg/l) the final unit will be displayed for next test. 

2.5. Auto Power off: tester will auto power off after test result show on LCD for 20 Seconds. 

2.6. The LCD flickering indicates low power of batteries, please replace two “AAA” alkaline batteries 

2.7. Sensor fault self checking : when turn on , tester will check sensor’s mode is normal or abnormal, if some abnormal thing is found which can auto repair ( about 10 seconds), if can not be repaired, LCD will display “ ER”.

2.8. If a new testing needed, press the switch button again and repeat the above step 4.2~

3. Notification 

3.1. Avoid any fall or strong shock. 

3.2. If noise gas with high concentration existed, may the tester won’t work normally. 

3.3. If testing is done under low voltage, certain error will be existed between the real value. 

3.4. To ensure the testing result, please wait 10 min to take the testing after your drinking. 

3.5. Please operate it strictly according to this instruction. If long time not use, when you first begin a new testing, the first two times testing result may be unreliable, just begin testing from the third time, otherwise the result will also not be accurate. 

3.6. Do not keep the tester in the environment of Corrosive gas (Chlorine etc) for use or deposit, also in other bad surroundings. 

3.7. Under normal detections, sensor life could be more than two years.

3.8. After Long time use, there may be dirt on the tester, please use clean cloth to wipe off. Do not use any hard object or the solvent with any Corrosive ingredient.
