2. If using Precision Mode, attach a clean mouthpiece.
3. Wait for the device to indicate readiness (e.g., a prompt on the IPS display (2) or a voice prompt).
4. Blow steadily into the air intake nozzle (1) for approximately 5 seconds.
5. The device will process the sample, and the result will be displayed on the IPS screen (2) within 1-15 seconds. Voice prompts will also announce the result.

3.4 Interpreting Results

The device displays alcohol concentration in various units and provides visual and auditory feedback:

• Green Indicator Light: Indicates a low or zero alcohol level (e.g., 0.000% BAC - "Not drinking").
• Yellow Indicator Light: Indicates a moderate alcohol level (e.g., 0.038% BAC - "Drinking status").
• Red Indicator Light: Indicates a high alcohol level (e.g., 0.088% BAC - "Drunkenness").

7. User Tips

• For most accurate results, wait at least 20 minutes after consuming alcohol or smoking before performing a test. This allows alcohol to be absorbed into the bloodstream and mouth alcohol to dissipate.
• Ensure a continuous and steady breath for the entire 5-second blowing time. Inconsistent blowing can lead to inaccurate readings.
• Always use a fresh mouthpiece for each individual test in Precision Mode to maintain hygiene and accuracy.
• Keep the device charged to ensure it's ready when needed.
• Remember that this device is for personal use and informational purposes only. It should not be used to determine fitness to drive or operate machinery.
