5. Setup
- Initial Charging: Before first use, fully charge the device using the provided USB-C cable and a compatible 5V USB power adapter. The battery indicator on the screen will show charging status. A full charge typically takes about 3 hours.
- First Use Calibration: For optimal accuracy, it is highly recommended to perform a manual calibration in an open, unpopulated environment with fresh air (e.g., outdoors) during the first use. Refer to Section 7 for calibration instructions.
6. Operation
6.1 Power On/Off
Press and hold the multi-function button for approximately 3 seconds to power the device on or off.
6.2 Reading the Display
The large color LCD screen displays the current CO2 concentration in parts per million (ppm). The device also features a tri-color indication light system around the display to quickly assess air quality:
- Green Light: 400-699 ppm (Good concentration)
- Yellow Light: 700-1499 ppm (Medium concentration)
- Red Light: 1499-5000 ppm (Dangerous concentration)

6.3 ECO Power-Saving Mode
To conserve battery, the device automatically enters ECO power-saving mode after 5 minutes of inactivity, turning off the screen. The device continues to monitor CO2 levels in the background. Press any button to reactivate the display.
7. Calibration
Calibration ensures the accuracy of your CO2 detector. The device supports both automatic and manual calibration.
7.1 Automatic Calibration
Automatic calibration is enabled by default. The device will periodically self-calibrate in environments with stable CO2 levels. You can manually toggle automatic calibration on or off.

7.2 Manual Calibration
To perform a manual calibration:
- Place the device in an open, unpopulated environment with fresh air (e.g., outdoors) for at least 10-15 minutes to allow CO2 levels to stabilize.
- Long press the multi-function button. The screen will display "CAL" and initiate a 200-second countdown.
- Keep the device in the fresh air environment until the countdown completes. The device will then be calibrated.

8. Alarm Settings
The device is equipped with an audible alarm that activates when the CO2 concentration exceeds a set threshold. The default alarm threshold is 1500 ppm.
8.1 Customizing the Alarm Value
To adjust the alarm threshold:
- Long press the multi-function button for approximately 5 seconds until the alarm value starts flashing.
- Press the button once to increment the flashing digit.
- Press the button twice quickly to move to the next digit.
- Once the desired alarm value is set, wait a few seconds for the device to save the setting automatically.
8.2 Deactivating the Alarm
The audible alarm function can be deactivated if desired. Follow the steps for customizing the alarm value and set it to 'OFF' or a similar indicator if available, or set the threshold to its maximum value (5000 ppm) to effectively disable it for typical indoor use.

9. Power Management
The PTH-10C is powered by a built-in 1000mAh lithium-polymer battery.
9.1 Battery Life
A fully charged battery provides up to 72 hours of continuous operation. Actual battery life may vary depending on usage patterns and environmental conditions.

9.2 Charging
Connect the device to a 5V USB power source using the provided USB-C cable. The battery icon on the display will indicate charging status. The device can be used while charging.
10. Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use liquid cleaners, abrasive materials, or solvents, as these can damage the sensor or casing.
- Storage: Store the device in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity when not in use for extended periods.
- Calibration: Regular calibration (as described in Section 7) is recommended to maintain measurement accuracy.
11. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate CO2 readings | Sensor drift; device not calibrated; sensor obstructed. | Perform a manual calibration in a fresh air environment. Ensure the sensor opening is clear. |
| Device does not power on | Battery is depleted. | Charge the device using the USB-C cable. |
| Alarm not sounding | Alarm function deactivated; alarm threshold set too high. | Check alarm settings (Section 8) and ensure it is enabled and the threshold is appropriate. |
| Short battery life | Battery not fully charged; frequent screen activation. | Ensure the device is fully charged. Utilize ECO power-saving mode. |
