Setup
- Battery Installation:
- Open the battery compartment cover on the back of the device.
- Insert 3 x 1.5V AAA batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
- Initial Power-On:
- Press and hold the Power On/Off Key (orange button) for a few seconds until the display lights up.
- The device will perform a self-test and count down before entering normal operation mode.
- Placement:
- For optimal detection, place the detector in an area where CO is likely to accumulate, such as near fuel-burning appliances, but not directly above them.
- Avoid placing it in direct sunlight, near vents, or in areas with high humidity.
- The back clip allows for easy attachment to clothing or bags for portable use.
Operating Instructions

- Power On/Off:
- To turn on, press and hold the Power On/Off Key.
- To turn off, press and hold the Power On/Off Key until the display shuts down.
- Reading the Display:
- The main number on the screen indicates the Carbon Monoxide concentration in Parts Per Million (PPM).
- The smaller number displays the ambient temperature in Celsius or Fahrenheit.
- Battery indicator is located at the top right.

- Mode Selection (MAX/MIN/HOLD):
- Press the MODE button to cycle through MAX (maximum reading), MIN (minimum reading), and HOLD (freezing the current reading) modes.
- Press the SET button to confirm selections or enter settings.
- Unit Selection:
- Press the UNIT button to switch between Celsius (°C) and Fahrenheit (°F) for temperature display.
- Auto Power-Off:
- The device will automatically shut down after 5 minutes of no operation to save battery life.
Maintenance
- Battery Replacement:
- When the low battery indicator appears on the display, replace the 3 x 1.5V AAA batteries promptly.
- Ensure correct polarity during installation.
- Cleaning:
- Wipe the exterior of the detector with a soft, damp cloth.
- Do not use abrasive cleaners, solvents, or immerse the device in water.
- Keep the gas sensor area clean and free from obstructions.
- Regular Testing:
- It is recommended to test the detector periodically to ensure proper function.
- Refer to the operating instructions for specific testing procedures.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Dead or incorrectly installed batteries | Replace batteries with new 1.5V AAA batteries, ensuring correct polarity. |
| No CO reading (0 PPM) | No CO present in the environment | This indicates a safe environment. If you suspect CO, move to fresh air and seek professional help. |
| Alarm sounds frequently without apparent CO source | Interference from other gases or high humidity | Relocate the detector away from potential sources of interference or high humidity. Ensure proper ventilation. |
| Low battery indicator persists after battery replacement | Faulty batteries or incorrect installation | Ensure batteries are new and correctly installed. If issue persists, contact support. |

Safety Information
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be fatal. This detector is designed to assist in the detection of CO gas. It is not a substitute for proper maintenance of fuel-burning appliances, including ventilation and exhaust systems, nor is it a substitute for visual inspection of such systems.
- General Precautions:
- Never ignore a CO alarm. The alarm indicates the presence of carbon monoxide, which can be fatal.
- Do not paint over the detector. Paint can clog the sensor openings and interfere with the unit's ability to detect CO.
- Keep the detector away from excessive dust, dirt, and grease.
- What to do if the Alarm Sounds:
- Immediately move to fresh air outdoors or open all doors and windows to ventilate the area.
- Call your emergency services, fire department, or a qualified technician.
- Do not re-enter the premises until the CO has dissipated and the source of the CO has been identified and corrected.
