1. Calibration - Be sure to do this calibration before drinking

To Check Alcohol Consumption

1. Press and hold the power button under LCD, and the number "7" will be displayed then will count down to "2".

2. After the digit "2" is displayed, the LCD will blink and beep. The numbers will be displayed again from "9" to "0" (Take your finger off the button from the digit "9")

3. The digit "0" will be displayed for 3 seconds, then blow into the inhaler between 3~4 seconds, and then the tester will switch off automatically. (This process is for inputting each body condition in advance, not for measuring the user's alcohol level)

4. In order to obtain a more accurate result, you should calibrate twice.

To Check Gas Leakage

1. Press and hold the power button under LCD, and the number "7" will be displayed then will count down to "2".

2. After the digit "2" is displayed, the LCD will turn blank and beep. The display will show the digit "9" and will count down to "0"

3. The digit "0" will be displayed for 3 seconds, and the power will automatically turn off.

4. In order to obtain a more accurate result, you should calibrate more than once.

2. Testing

To Check Alcohol Consumption

1. Press the power button under LCD for 2 seconds, and the following numbers, "7" to "0" will be displayed and beep.

2. After the beep, blow immediately into the tester for 3~4 seconds, Exhale a consistent amount of air each time and at the same angle.

3. The number "0" will blink for about 3 seconds and then the test result will be displayed along with a beep sound on the LCD. The electric power will automatically shut off.

4. In order to obtain a more accurate result, you should use the tester repeatedly 2~3 times.

To Check Gas Leakage

1. Press the power button under LCD for 2 seconds, and the following numbers, "7" to "0" will be displayed and beep.

2. When the number "0" on the LCD is displayed, a beep will sound. The product will test for any gas in the atmosphere.

3. The number "0" will blink for about 3 seconds and then the test result will be displayed along with a beep sound on the LCD. The electric power will automatically shut off.

4. In order to obtain a more accurate result, you should use the tester repeatedly 2~3 times.

1. Because the sensor needs a warm-up time, it is necessary to calibrate more than once before your measuring alcohol level.

2. Allow 30 minutes after consuming alcohol or smoking. This helps to ensure the breath sample is taken from your lungs and not from the alcohol within your mouth, which may result in a higher reading. In some cases, it may take up to one hour to reach the highest blood alcohol level after the last consumption of alcohol.

3. Because the sensor is very sensitive, the unit will not function correctly if it is wet or damaged. In this case, the calibration before measuring your alcohol level is especially required.

4. Generally alcohol sensor can be affected by temperature and humidity. Therefore, it could happen the allowable margin of error.

5. Each individual's body responds to the consumption of alcohol differently.

6. The alcohol level in our body decreases with the passage of time

7. At low battery stage, not operated without any indication on LCD. New battery replacement is necessary.

The Key technology for the function and performance of Personal Alcohol Detector is the gas sensor. It uses advanced MEMS gas sensor, which equips our products with high quality accuracy.

• Calibration function
• Safe Mate is made with a low voltage circuit design. Therefore, the life of batteries is longer than any other products, and it can be used more than 800 times.
• The warm-up time is short, so the test result can be shown within about 7 seconds after pressing the power button.
•  With a one-touch controlling and LCD screen, it is easy to read the result of the consumed alcohol, even at night.
• Safe Mate displays on the LCD screen for both of %BAC and g/l
• Safe Mate has a very attractive design to end-users.
•  The display level is composed of total 20 steps from 0.00 to 0.19 for %BAC and 0.1 to 1.9g/l.
• Safe Mate is easy to carry anywhere.
•  There is a beep sound before and after checking the content of blood alcohol.

• This product should be used only to give an indication of the possible presence of alcohol in the blood. Do not use it to determine intoxication or whether it is safe to drive a vehicle or operate equipment! This product is just for your reference. This detector assumes no liability for the result of alcohol use.
• Do not use it while drinking or smoking. (Measuring alcohol level at least 30 minutes after consuming alcohol)
