1. Introduction
Thank you for choosing the Tadeto TE026 Portable Carbon Monoxide Detector. This device is designed to accurately detect carbon monoxide (CO) concentrations in the air and alert users to potentially dangerous levels through audible and visual alarms. Please read this manual thoroughly before use to ensure proper operation and safety.
2. Important Safety Information
- Carbon Monoxide (CO) Warning: Carbon monoxide is a colorless, odorless, and tasteless gas that can be fatal. This detector is designed to assist in detecting the presence of CO gas. It is not a substitute for proper maintenance of fuel-burning appliances or ventilation systems.
- Placement: Position the detector in areas where CO may be present, such as near fuel-burning appliances, but avoid direct exposure to exhaust fumes or high humidity.
- Alarm Response: If the alarm sounds, immediately move to fresh air, call emergency services, and do not re-enter the area until it has been deemed safe by professionals.
- Battery Safety: Use only specified AAA alkaline batteries. Do not mix old and new batteries or different types of batteries. Dispose of used batteries responsibly.
- Operating Environment: Do not expose the device to extreme temperatures, direct sunlight, or excessive moisture.

5.2 Powering On/Off
- To Power On: Press and hold the Power Button (ⓔ) for approximately 2 seconds. The device will perform a self-test and warm up for about 30 seconds. During warm-up, the display may show a countdown or fluctuating readings before settling to 0 PPM in clean air.
- To Power Off: Press and hold the Power Button (ⓔ) for approximately 2 seconds until the display turns off.
6. Operating Instructions
6.1 Reading the Display
The 2.4-inch backlit LCD screen displays real-time CO concentration in Parts Per Million (PPM). It also shows battery status, alarm indicators, and maximum detected value.

6.2 Alarm Functionality
The detector features both audible and visual alarms.
- Default Low Alarm: 35 PPM
- Default High Alarm: 200 PPM
- When CO concentration exceeds the preset low alarm value, the device will emit a beeping sound and the screen will flash red.
- If the concentration reaches the high alarm value, the sound and flashing frequency will increase.
- To Mute Alarm: Short press the Sound Button (🔊) to temporarily turn off the audible alarm. The visual alarm will continue. The sound will be re-enabled by default on the next power-on.

6.3 Adjusting Alarm Values
The low and high alarm values can be manually adjusted:
- Low alarm values can be set between 20-199 PPM.
- High alarm values can be set between 200-1000 PPM.
- Refer to the detailed instructions in the included user manual for specific steps on how to enter the settings menu and adjust these values.
6.4 Data Hold Function
To freeze the current CO reading on the display, short press the HOLD button. Press it again to release the hold and resume real-time measurement.
6.5 Backlight Control
Short press the Backlight Button (💡) to turn the display backlight on or off, improving visibility in low-light conditions.
7. Maintenance
7.1 Cleaning
- Wipe the device with a soft, dry cloth.
- Do not use abrasive cleaners, solvents, or immerse the device in water.
7.2 Battery Replacement
When the battery indicator on the display shows low power, replace all three AAA batteries promptly to ensure continuous operation and accurate readings. Follow the battery installation steps in Section 5.1.
7.3 Storage
When not in use for extended periods, remove the batteries and store the detector in its provided storage bag in a cool, dry place, away from direct sunlight and extreme temperatures.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Batteries are dead or incorrectly installed. | Check battery polarity and replace with fresh AAA batteries. |
| No CO reading (0 PPM) in suspected CO presence. | Device still in warm-up phase; CO levels are below detection threshold; sensor malfunction. | Wait 30 seconds after power-on. Ensure CO source is active. If issue persists, contact customer support. |
| Alarm sounds frequently without apparent CO source. | High background CO levels; detector sensitivity. | Ventilate the area. Ensure no hidden CO sources. Consider adjusting alarm thresholds if appropriate for your environment (refer to Section 6.3). |
| Display is dim or unreadable. | Backlight is off; low battery. | Press the Backlight Button (💡). Replace batteries if the battery indicator is low. |
