Neoteck Portable Carbon Monoxide Detector (Model NTK236) User Manual

1. Introduction

The Neoteck Portable Carbon Monoxide (CO) Detector is designed to provide real-time monitoring of CO concentration in various environments. Equipped with a high-precision sensor, visual and audible alarms, and a rechargeable battery, this device helps ensure your safety by alerting you to potentially dangerous CO levels. It is suitable for use in homes, cars, RVs, tents, and during outdoor activities like camping and caravanning.

2. Important Safety Information

Read all instructions carefully before using this device. Failure to follow these instructions may result in property damage, injury, or death.

• Carbon Monoxide (CO) is a colorless, odorless, and tasteless gas that can be fatal. This detector is intended to detect carbon monoxide gas from any source of combustion.
• This device is not a substitute for proper ventilation and maintenance of fuel-burning appliances. Ensure all fuel-burning equipment is regularly inspected and maintained by qualified professionals.
• Do not block the sensor opening. Ensure the detector is placed in an area where air can freely circulate to the sensor.
• In case of an alarm: Immediately move to fresh air outdoors or open all doors and windows to ventilate the area. Call emergency services if symptoms of CO poisoning are present. Do not re-enter the premises until the CO source has been identified and corrected, and the area has been thoroughly ventilated.
• Keep out of reach of children.

Device Components

• Digital Display: Shows CO concentration in PPM, battery level, and alarm status.
• Power Button: Used to turn the device on/off.
• Brightness Adjustment Button: Cycles through display brightness levels.
• Sound/Alarm Toggle Button: Enables or disables audible alarms.
• Type-C Charging Port: For recharging the internal battery.
• Lanyard Attachment Point: For easy carrying.

5. Setup

5.1. Charging the Device

Before first use, fully charge the detector. The device features a built-in 700mAh rechargeable battery.

1. Connect the provided Type-C USB charging cable to the charging port on the detector.
2. Connect the other end of the cable to a standard USB power adapter (not included) or a power bank.
3. The battery indicator on the display will show charging status. A full charge typically takes 3 to 4 hours.
4. Once fully charged, the device can last for over 20 days with 6-7 activations per day, or approximately 10 hours of continuous use.

5.2. Initial Power On

To turn on the device, press and hold the power button for a few seconds until the display illuminates.

6. Operating Instructions

6.1. Power On/Off

• To Power On: Press and hold the power button (⏻) for approximately 2 seconds.
• To Power Off: Press and hold the power button (⏻) for approximately 2 seconds.

6.2. Adjusting Brightness

The device offers three brightness levels for its display: dark, moderate, and bright.

• Press the brightness adjustment button (💡) repeatedly to cycle through the available brightness settings.

6.3. Adjusting Sound/Alarm

You can enable or disable the device's audible alarms.

• Press the sound/alarm toggle button (🔊) to switch the sound on or off.
• When the sound is turned off, all alarm sounds will also be deactivated. This allows for use in quiet environments without disturbance.

6.4. Auto-Off Function

The detector is designed with an auto-off function that automatically shuts off after 5 minutes of inactivity to conserve battery life.

• To disable the auto-off function for continuous monitoring, press and hold the power button (⏻) for an extended period (longer than 2 seconds for power on/off) until a specific indicator appears or the device confirms continuous mode. Refer to the on-screen prompts for confirmation.
• For continuous monitoring over extended periods, it is recommended to connect the device to a mobile power source via the Type-C cable.

7. Understanding Carbon Monoxide Levels and Alarms

The detector provides both visual and audible indications of CO concentration. The color bar on the display changes, and a buzzer sounds at specific PPM levels.

• <35 ppm (Green / Good): Only the color bar flashes slowly. The air quality is considered good.
• 35-50 ppm (Yellow / Slight): The color bar flashes slowly, indicating a slight CO presence.
• 51-200 ppm (Orange / Moderate): The color bar flashes slowly, and the buzzer will sound "BB...BB..." twice. Ventilation is required.
• >200 ppm (Red / Serious): The color bar flashes slowly, and the buzzer will sharply sound "BBB...BBB..." twice. This indicates a dangerous level of CO requiring immediate action.

Note: If the sound is switched off, the buzzer will also be switched off.

8. Testing the Device

To safely test the functionality of your Neoteck CO Detector and observe changes in CO values, you can use the following methods:

• Cigarette Smoke: CO is present in cigarette smoke. Exposing the detector to cigarette smoke will show value changes on the display.
• Incompletely Burned Wood: Place the detector near incompletely burned wood (e.g., smoldering embers from a campfire or fireplace) to observe changes in CO levels.

Always perform tests in a well-ventilated area and avoid prolonged exposure to high CO concentrations during testing.

9. Maintenance

9.1. Charging

Regularly charge the device to ensure optimal performance. Refer to Section 5.1 for detailed charging instructions.

9.2. Cleaning

To maintain the detector's accuracy and longevity:

• Wipe the exterior of the device with a soft, dry cloth.
• Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the device or interfere with sensor operation.
• Ensure no liquids enter the device, especially near the sensor opening.

10. Troubleshooting

10.1. Detector always shows "0"

Under normal circumstances, there is no toxic CO gas in the air, so the detector will display a value of "0" most of the time. It will only show values in certain situations where CO is present. Common sources of CO include:

• Home Heating: Devices using gas, wood, or coal can emit CO if combustion is incomplete.
• Car Exhaust: CO can build up in a closed garage or car with prolonged engine use.
• Cooking: Gas stoves with poor ventilation or malfunctions can produce CO.
• Smoking: Indoor smoking elevates CO levels.

If you suspect CO is present but the device shows "0", ensure the device is functioning correctly by performing a safe test (see Section 8).

10.2. Alarm sounds unexpectedly

• Check for any potential sources of CO in the vicinity.
• Ensure adequate ventilation in the area.
• If the alarm persists and no obvious CO source is found, move to fresh air and contact emergency services if you experience symptoms of CO poisoning.

10.3. Device not turning on

• Ensure the battery is sufficiently charged. Connect the device to a power source using the Type-C cable and allow it to charge for at least 30 minutes before attempting to power it on again.
• If the issue persists, contact customer support.
