2. Important Safety Information
WARNING: This device is designed to detect carbon monoxide gas from any source of combustion. It is NOT designed to detect smoke, fire, or other gases. Carbon monoxide is an odorless, colorless, and tasteless gas that can be fatal. This detector is intended to assist in the prevention of accidental carbon monoxide poisoning. It is not a substitute for proper use and maintenance of fuel-burning appliances, including regular inspection of heating systems and chimneys.
- Do not paint the detector. Paint can clog the sensor openings and interfere with the unit's ability to detect CO.
- Do not block the ventilation openings on the device.
- Test the detector weekly to ensure proper operation.
- Do not install in areas with extreme temperatures or humidity.
- Keep out of reach of children.

4. Setup and Installation
The Pildegro DP-20A is designed for plug-and-play installation. No complex wiring is required.
- Unpack: Carefully remove the detector from its packaging.
- Initial Charge: Before first use, it is recommended to plug the detector into a standard AC outlet for at least 24 hours to fully charge the internal 1000mAH backup battery. The battery icon on the display will indicate charging status.
- Placement:
- Install the detector in a standard AC wall outlet.
- For optimal CO detection, place the detector at chest height in areas where CO may be present, such as near fuel-burning appliances (furnaces, water heaters, gas stoves) or in living areas and bedrooms.
- Avoid placing the detector in direct sunlight, near vents, fans, or in areas with high air circulation that could dilute CO readings.
- Do not place behind curtains or furniture that could obstruct the sensor.
- Consider installing one detector on each level of your home, especially near sleeping areas.
- Power On: Once plugged in, the device will automatically power on and begin its self-test sequence. The display will light up, and the alarm may briefly sound.

5. Operating Instructions
The DP-20A features a user-friendly interface with a clear LED display and intuitive controls.
5.1 Powering On/Off
- Power On: The device automatically powers on when plugged into an AC outlet. If operating on battery backup, press and hold the power button (usually marked with a circle or power symbol) for a few seconds until the display lights up.
- Power Off: To power off, unplug the device from the AC outlet. If operating on battery, press and hold the power button until the display turns off.
5.2 Switching Display Modes
The DP-20A offers a dual-mode display, allowing you to focus on CO levels or environmental conditions (Temperature and Humidity).
- Press the "Mode" button (often labeled 'M' or with an icon) to switch between the primary CO display and the secondary Temperature/Humidity display.
- The primary interface typically shows CO PPM prominently.
- The secondary interface will show temperature in Fahrenheit or Celsius and relative humidity percentage.
5.3 Adjusting Display Brightness
The display brightness can be adjusted for comfort, especially during nighttime.
- Press the "Brightness" button (often labeled with a sun icon) to cycle through brightness levels: High, Low, and Off.
- Selecting "Off" will turn off the display light while the detector continues to monitor CO levels and will activate the alarm if necessary.

6. Display Modes and Alarms
The DP-20A provides clear visual and audible indications of CO levels and environmental conditions.
6.1 Carbon Monoxide (CO) Level Indication
The LED display uses a 3-segment color system to indicate CO concentration:
- Green Light / Low Level: Indicates CO levels below 50 ppm. This is considered a safe range.
- Yellow Light / Caution: Indicates CO levels between 50-99 ppm. This is a caution level, and investigation into the source of CO is recommended.
- Red Light / High Level: Indicates CO levels at or above 100 ppm. This is a dangerous level, and immediate action is required. The alarm will sound.
6.2 Alarm Operation
- When CO levels reach or exceed 100 ppm, the detector will emit an 80dB loud alarm.
- The frequency of the alarm increases as CO levels rise, providing a more urgent warning for higher concentrations.
- In case of an alarm, immediately move to fresh air, call emergency services, and do not re-enter the premises until it has been deemed safe by professionals.
- To silence the alarm temporarily, press the "Test/Silence" button. The alarm will reactivate if CO levels remain high.
6.3 Temperature and Humidity Display
When in the secondary display mode, the device shows the current ambient temperature and relative humidity. These readings are for informational purposes and do not trigger alarms.

7. Maintenance
Regular maintenance ensures the longevity and reliability of your CO detector.
- Weekly Test: Press and hold the "Test/Silence" button for a few seconds until the alarm sounds. This confirms the sensor, alarm, and battery are functioning correctly.
- Cleaning: Dust and debris can accumulate on the detector and interfere with its operation.
- Gently vacuum the detector cover and vents with a soft brush attachment at least once a month.
- Do not use cleaning solvents or waxes on the detector.
- Do not spray air fresheners, hair spray, or other aerosols near the detector.
- Battery Maintenance: The internal 1000mAH lithium-ion battery is rechargeable and designed to provide backup power. Ensure the device is regularly plugged into an AC outlet to keep the battery charged. The battery is designed to last the lifespan of the 10-year sensor and is not user-replaceable.
- End of Life: The detector has a 10-year sensor lifespan. After 10 years, the device will indicate an end-of-life warning, and it should be replaced immediately.
