2. Safety Information
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be fatal. This device is intended to detect CO gas and provide alerts, but it is not a substitute for proper ventilation and maintenance of fuel-burning appliances. Always ensure adequate ventilation when using fuel-burning devices.
CO Hazard Levels and Alarms:
- 0-49 PPM: Green bar flashing. No alarm alert. Indicates normal or safe levels.
- 50-99 PPM: Yellow bar flashing. Slow "di di" sound regularly. Indicates OSHA Exposure Limits are being approached or exceeded.
- 100-500 PPM: Red bar flashing. Rapid "di di" sound alert. Indicates dangerous levels that can cause mild headache, fatigue, nausea, dizziness, and potentially death within 2 to 3 hours.
If the alarm sounds, immediately move to fresh air and ventilate the area. Seek medical attention if symptoms of CO poisoning are experienced.

5.2 Changing Temperature Units
While the device is on, a single short press of the main button will toggle the temperature display between Celsius (°C) and Fahrenheit (°F).
5.3 Adjusting CO Alert Value
The default CO alert value is 50 PPM. You can customize this value between 25 PPM and 125 PPM. To adjust:
- Double-tap the main button to enter adjustment mode. The CO PPM digits will flash.
- Use short presses of the button to cycle through the desired PPM values.
- Once the desired value is displayed, press and hold the button to confirm and exit adjustment mode.
Note: Please read the manual carefully before customizing the alert value to understand the implications of different CO levels.
