## Questions & Answers

**Q: How do I use the device correctly for carbon monoxide detection?**
A: Step1: Turn on the CT-300 in a fresh air environment (e.g., a well-ventilated outdoor space) and wait for it to warm up.

**Q: Why do I smell a carbon monoxide leak, but the CT-300 doesn’t detect anything?**
A: The smell you notice is unlikely to originate from carbon monoxide (CO), as CO is colorless and odorless. The odor may be caused by another gas, such as a combustible gas. We recommend using a combustible gas detector to identify the source.

**Q: Why can't carbon monoxide be detected in a closed room?**
A: When there is no significant source of combustion indoors, even in a closed room, carbon monoxide will not be generated. The gases exhaled by humans contain carbon dioxide (CO2), which is a different gas from carbon monoxide (CO).

**Q: Why can't carbon monoxide be detected even when there is a combustion source present?**
A: Not all combustion produces CO gas, only incomplete combustion does, which is characterized by a red/yellow flame in most cases. Also, ensure proximity during measurement to prevent gas dispersion, which may lead to undetectable concentrations.
