Over time, all breathalyzers require recalibration to maintain accuracy. BACtrack recommends recalibrating your C6 every 6-12 months, or after approximately 200-300 tests, whichever comes first. Information on how to arrange recalibration services can be found on the official BACtrack website or by contacting customer support.
If you encounter issues with your BACtrack C6, try the following solutions:
| Problem | Possible Solution |
|---|---|
| Device does not turn on. | Check battery installation. Replace with a fresh AAA battery. |
| Inaccurate or inconsistent readings. | Ensure 15 minutes have passed since last drink/meal. Use proper blowing technique. Device may require recalibration. |
| Cannot connect to smartphone app. | Ensure Bluetooth is on. Restart both the device and the app. Try re-pairing the device in the app settings. |
