4.3. Understanding Test Results

Test results are displayed in %BAC and g/L units on the digital screen. The device also uses a tricolor indicator lamp to provide a quick visual interpretation of the results.

• سبز روشنی: When the detection result is less than 0.02% BAC (or 0.2 g/L), the green light remains on, and no buzzer sound is emitted. This indicates a non-drinking state.
• پیلی روشنی: When the detection result is between 0.02% BAC (or 0.2 g/L) and less than 0.08% BAC (or 0.8 g/L), the yellow light remains on, and the buzzer emits a slow, continuous sound. This indicates a drinking state, caution is advised.
• سرخ روشنی: When the detection result is greater than or equal to 0.08% BAC (or 0.8 g/L), the red light remains on, the display screen flashes "danger", and the buzzer emits a rapid, continuous sound. This indicates a drunken state, and driving is strictly prohibited.

5 دیکھ بھال

• صفائی: Regularly wipe the exterior of the device with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water. Ensure the sensor area is free from dust and debris.
• ذخیرہ: آلے کو ٹھنڈی، خشک جگہ پر، براہ راست سورج کی روشنی اور انتہائی درجہ حرارت سے دور رکھیں۔
• بیٹری کی دیکھ بھال: بیٹری کی زندگی کو طول دینے کے لیے، بار بار ڈیوائس کو مکمل طور پر ڈسچارج کرنے سے گریز کریں۔ اسے باقاعدگی سے چارج کریں، چاہے مسلسل استعمال میں نہ ہوں۔

6 خرابیوں کا سراغ لگانا

• ڈیوائس آن نہیں ہو رہی ہے: Ensure the device is fully charged. If the issue persists, try charging with a different USB cable or power source.
• غلط پڑھنا: Ensure the device has completed its warm-up cycle. Avoid testing immediately after consuming alcohol, smoking, or using mouthwash, as this can affect accuracy. Allow at least 20 minutes after consumption before testing. Ensure a continuous and sufficient breath sample فراہم کی جاتی ہے.
• "Warm up" message persists: If the device repeatedly shows "warm up" or takes an unusually long time, it might indicate the sensor needs to be preheated multiple times, especially after long periods of non-use.
• کوئی ڈسپلے یا جزوی ڈسپلے نہیں: Check battery level. If fully charged and issue persists, contact customer support.
