Product description and features: 1. Professional airway settings; 2. Three conversion units for blood alcohol concentration (%BAC / ‰BAC / mg/L); 3. Blue backlit LCD display; 4. Fast response and recovery time; 5. Automatic shut-off; 6. Low battery warning; 7. Interchangeable mouthpieces. Five mouthpieces are included. Product specifications: Product dimensions: 112 × 61 × 29 mm; Packaging dimensions: 165 × 118 × 45 mm; Net weight: 69 g; Gross weight: 196 g. Instructions for use: Press and hold the "POWER" button on the front of the display for 1 to 3 seconds to start a 10-second countdown to warm up the sensor. Once "BIOW" appears on the display, blow into the air outlet for approximately 3 to 6 seconds. During the approximately 5-second reaction time, the test results are displayed on the LCD screen. The device switches off automatically after about 5 seconds. Now, hold your mouth near the exhalation sensor and exhale continuously for 3 to 6 seconds. The display will show the test results. The message "Caution" will appear for values within the following ranges: √ from 0.02% (or 0.2 g/l) to 0.05% (or 0.5 g/l); from 0.05% (or 0.5 g/l) to 0.08% (or 0.8 g/l). The message "Danger" will appear for values within the following ranges: √ ≥ 0.05% (or 0.5 g/l); ≥ 0.08% (or 0.8 g/l). The binding national standard "Regulations on Blood Alcohol Concentration of Motor Vehicle Drivers" stipulates that driving a motor vehicle with a blood alcohol concentration (BAC) of 0.2 mg/ml or higher is considered driving under the influence of alcohol (FUA); driving a motor vehicle with a BAC of 0.8 mg/ml or higher is considered driving while intoxicated. Description of the audible alarm signal: If the test result is below the predefined alarm threshold (deviation greater than 0.2‰ BAC), it is displayed digitally without an audible signal. If the test result is below the predefined alarm threshold (deviation less than or equal to 0.2‰ BAC), it is displayed digitally and an audible pre-warning signal is emitted. (This function is only available if the alarm threshold is above 0.20‰ BAC.)
