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 switch button last for 1S, the tester would be on with a buzzer brief ringing, ‘Wait’ flashes and Warm-up of 20 sec begin, the fig on the LCD Countdown from 20-0, please wait now. Until “Wait” disappears, tester will send out a ring, meantime “BLOW” and “C” gliding, also the small car icon twinkles, now the test could begin.


2.3. Have a deep breath before testing, and blow directly to gas entry until a buzzer ringing, “000” twinkles for 4S on the screen, at the same time the “BLOW” disappear and ‘TEST’ shown.


2.4. Tester will send out a ring after testing process finished, the LCD screen would give the readout of temporal alcohol concentration (If the testing result is lower than preset level, only the car icon twinkles; If the testing result is higher than preset level, the buzzer ringing continuously, at the same time the “Hi” and “No Driving” icon twinkles), this result would be keep on the screen for 10 sec, then cut off the power supply automatically with two buzzer ringing.

2.5. If a new testing needed, press the switch button again and repeat the above step 4.2~4.4.



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.
