Properties 1. 3 Phase Breathalyzer Test 2. Quick response and summary 3. Flashlight function 4. Keyring 5. Required 2 "AAA" alkaline batteries Placing batteries 1. Open the battery compartment on the back of the unit. 2. Please insert 2 "AAA" alkaline batteries and make sure the polarity is correct. Compartment closure. How to use the breathalyzer 1. To turn on the breathalyzer, press and hold the power button. Yellow and red lamps light up during the heating phase. Press and hold the power button until the green light comes on and the warm-up phase ends. 2. Press and hold the power button until the test is complete. NOTE: The warm-up phase is between 0 and 15 seconds and depends on sensor status or time. On the surface of the alcohol sensor there is always a large amount of gas and impurities. If you unpack the tester or have not used it for a long time, the appliance needs more time to clean and heat the sensor. Therefore, you need to press the power button again and repeat it several times. Alcohol concentration test 1. When heating is complete, wait for 3-5 seconds and then blow for 3 to 5 seconds. 2. See test result: 1. Green Light Only: Safe The alcohol concentration is less than 0.02% BAC (0.1 Mg BRAK) 2. Yellow Light Only: Caution: Alcohol concentration is between 0.02% and 0.05% BAK (0.1 – 0.25 Mg BRAK) 3. Red and Yellow Light together: Danger: Alcohol concentration is higher than 0.05 BAK (0.25 Mg BRAK) 3. Release the power button when the test is finished. 4. For more accurate results, you can repeat the test 3 or 4 times. NOTE: Avoid inaccurate results. Do not test when the flashlight is on. Using the flashlight Slide the flashlight switch to the On position to turn it on. To turn it off, slide the switch back to the Off position. Technical details • Sensor: modern semiconductor oxide alcohol sensor • Measurement range: 0.00% – 0.1% BAK (0.00-0.05mg/l BRAK) • Test accuracy: 0.01% BAK (0.05 mg/l BRAK • Input voltage: 2 x 1.5 V, "AAA" Battery Alkaline • Operating time: Heating phase: 15-30 sec. Response Time: 5 Sec. Dimensions: 73 x 39 x 30 mm Caution • After drinking a break of at least 20 minutes is recommended for testing. It is the time needed for alcohol to pass into the blood through the digestive tract and for residual alcohol in the mouth to dissolve. • For accurate results, repeat the test after at least three minutes. • Do not smoke and eat minutes before the test. • Do not use chemicals to clean the tester directly. • Do not use alcohol or insecticides near the test device.
