1. Introduction
The Neoteck Portable CO Detector AK18A is a compact, high-precision carbon monoxide (CO) monitoring device designed for safety in various environments. Featuring a rechargeable battery, adjustable alarm, and clear LCD display, it provides real-time CO concentration readings and alerts to help ensure your safety in homes, caravans, cars, and during outdoor activities like camping.
2. Safety Information
WARNING: Carbon Monoxide is a colorless, odorless, and tasteless gas that can be fatal. This detector is designed to alert you to the presence of CO, but it is not a substitute for proper maintenance of fuel-burning appliances or adequate ventilation. Always seek fresh air immediately if the alarm sounds.
- Do not block the detector's ventilation openings.
- Do not paint the detector.
- Do not expose the detector to extreme temperatures or humidity.
- Test the detector regularly as per instructions.
- This device is intended for general CO detection and should not be used for specific industrial or medical applications.

- Battery Indicator: Shows current battery level.
- Sound Icon: Indicates if the audible alarm is enabled or disabled.
- Color Bar: Visual indicator of CO concentration levels (Good, Slight, Moderate, Serious).
4. Setup
4.1 Initial Charging
Before first use, fully charge the detector. Connect the included Type-C USB cable to the detector's charging port and plug the other end into a standard USB power adapter (not included).
- The detector features a 700mAh rechargeable battery.
- A full charge provides approximately 11 hours of continuous use.
- With automatic power-off after 5 minutes of no operation (used 6-7 times a day), the battery can last for over 20 days.
- For continuous monitoring, the device can be connected to a power source via the Type-C cable.
4.2 Power On/Off
- To Power On: Press and hold the Power button (top button) for a few seconds until the display illuminates.
- To Power Off: Press and hold the Power button for a few seconds until the display turns off.
5. Operating Instructions
5.1 CO Monitoring
Once powered on, the detector will automatically begin monitoring carbon monoxide levels in the air. The CO concentration will be displayed in PPM on the LCD screen, with a data refresh rate of 1 second.
5.2 CO Concentration Visualization and Alarm Levels
The detector provides both visual (color bar on screen) and audible alerts based on CO concentration:
| CO Concentration | Visual Indication (Color Bar) | Audible Alarm | Interpretation |
|---|---|---|---|
| < 35 ppm | Green (Good) | None | Comfortable, safe levels. |
| 35 - 50 ppm | Yellow (Slight) - Flashes slowly | None | No significant discomfort, but CO is present. |
| 51 - 200 ppm | Orange (Moderate) - Flashes slowly | "BB...BB..." (twice) | Ventilation required. Take action to reduce CO. |
| > 200 ppm | Red (Serious) - Flashes slowly | "BBB...BBB..." (twice) | Dangerous levels. Evacuate immediately. |
Note: If the sound function is switched off, the audible buzzer will also be switched off, regardless of CO concentration.
5.3 Adjusting Sound and Backlight
- Sound On/Off: Press the Sound button (middle button) to toggle the audible alarm on or off. The sound icon on the display will indicate the current status.
- Backlight/Brightness: Press the Backlight/Brightness button (bottom button) to adjust the screen's illumination.
6. Maintenance
6.1 Cleaning
- Wipe the detector's exterior with a soft, dry cloth.
- Do not use abrasive cleaners, solvents, or detergents, as these can damage the device or sensor.
- Ensure no liquids enter the device, especially the sensor area.
6.2 Battery Care
- Recharge the battery when the low battery indicator appears on the display.
- Avoid fully discharging the battery frequently to prolong its lifespan.
- If storing the device for an extended period, charge it periodically (e.g., every 3-6 months) to maintain battery health.
6.3 Sensor Lifespan
The CO sensor has a limited lifespan. While not explicitly stated, most CO detectors require replacement after 5-10 years. Refer to the manufacturer's website or contact support for specific sensor lifespan information for this model.
7. Troubleshooting
7.1 Common Issues
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on | Low battery or device off. | Charge the device fully. Press and hold the Power button to turn on. |
| No audible alarm when CO is detected | Sound function is off. | Press the Sound button to enable the audible alarm. Check the sound icon on the display. |
| Inaccurate readings or no reading | Sensor obstruction or malfunction. | Ensure sensor openings are clear. If problem persists, contact support. |
| Battery not charging | Faulty cable, adapter, or charging port. | Try a different Type-C cable and USB power adapter. Ensure connections are secure. |

9. User Tips
- Optimal Placement: For best results, place the detector at breathing height, away from direct drafts, vents, or windows. In a car, ensure it's not obstructed by seats or other items.
- Regular Checks: Even without an alarm, periodically check the CO reading on the display to familiarize yourself with normal background levels in your environment.
- Travel Companion: Its mini size makes it ideal for travel. Always pack it when staying in hotels, cabins, or using rental vehicles.
- Continuous Monitoring: If you need constant monitoring (e.g., in an RV or while camping with a generator), connect the detector to a portable power bank via its Type-C port.
- Understand Alarm Tones: Familiarize yourself with the different alarm tones for moderate and serious CO levels to react appropriately.
