3. Setup
3.1 Initial Charging
Before first use, fully charge the detector. The device is equipped with a 1500 mAh efficient lithium battery, providing approximately 72 hours of battery life on a full charge.
- Locate the Type-C charging port on the device.
- Connect the provided Type-C charging cable to the detector and the other end to a compatible USB power adapter (e.g., 5V DC, 10W).
- The battery indicator on the screen will show charging status. Charge until the indicator shows a full battery.
Note: Some users have reported issues with C-to-C USB cables. If charging problems occur, please use a USB-A to USB-C cable.

3.2 Powering On/Off
- To power on: Press and hold the power button (usually located on the side or top) for a few seconds until the screen illuminates.
- To power off: Press and hold the power button again until the device shuts down.
4. Operating Instructions
4.1 Understanding the Display
The 2.48-inch HD screen provides real-time readings from all integrated sensors. The display typically shows:
- CO (Carbon Monoxide): Measured in PPM (Parts Per Million). Range: 0-500 PPM.
- O2 (Oxygen): Measured in %VOL (Percentage by Volume). Range: 0-30% VOL.
- Temp (Temperature): Measured in °C or °F. Range: 0°C - 50°C (32°F - 122°F).
- Humidity: Measured in % RH (Relative Humidity). Range: 0-95% RH.
- Atmos (Atmospheric Pressure): Measured in hPa (hectopascals). Range: 300-1100 hPa.
- Altitude: Measured in feet (ft).
- Battery Level Indicator.

4.2 Alarm Logic and Safety Guidelines
The detector is designed to provide audible alarms when CO or O2 levels exceed or fall below safe thresholds. Refer to the following general guidelines for alarm triggers:
- Carbon Monoxide (CO) Alarm: An alarm will sound if CO concentration reaches dangerous levels. Evacuate the area immediately and seek fresh air if the CO alarm activates.
- Oxygen (O2) Alarm: Alarms will trigger for both low oxygen (below safe levels) and high oxygen (above safe levels) concentrations. Both conditions can be hazardous.
Always prioritize safety. If an alarm sounds, follow established safety protocols for your environment. Do not ignore alarms.
4.3 Usage Scenarios
The portable design and integrated lanyard make this detector suitable for a variety of applications:
- Outdoor Activities: Ideal for camping, hiking, climbing, and boating to monitor air quality and altitude.
- Travel: Compact size makes it easy to carry for personal safety during travel.
- Indoor Monitoring: Can be used to track CO, O2, temperature, and humidity in enclosed spaces.

5. Maintenance
5.1 Cleaning
To maintain optimal performance, keep the detector clean:
- Wipe the exterior with a soft, dry cloth.
- Do not use abrasive cleaners, solvents, or harsh chemicals.
- Ensure no liquids enter the sensor openings or charging port.
5.2 Battery Care and Storage
- Recharge the battery when the low battery indicator appears to ensure continuous operation.
- For long-term storage, charge the device to approximately 50% and store it in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid fully discharging the battery for extended periods, as this can reduce its lifespan.
6. Troubleshooting
- Device not powering on: Ensure the battery is charged. Connect to a power source and try again. If still unresponsive, contact support.
- Charging issues (especially with C-to-C cables): If the device does not charge with a USB-C to USB-C cable, try using a USB-A to USB-C cable. This has been identified as a potential compatibility issue.
- Inaccurate readings: Ensure the sensor openings are not obstructed. Avoid exposing the device to extreme dust, humidity, or temperature fluctuations that are outside its operating range. Allow the device to stabilize in a new environment for a few minutes.
- Alarm sounds unexpectedly: Immediately follow safety protocols for CO or O2 alarms. If you suspect a false alarm, move to a well-ventilated area and observe if the readings normalize. If alarms persist without apparent cause, the sensor may require calibration or service.
