1. Introduction and Overview
The AEGTEST AGT-3000 is a portable carbon monoxide (CO) detector designed to provide timely and accurate detection of CO levels in various environments. Equipped with a high-precision DDS sensor, it offers reliable performance for your safety.

Key features include a detection range of 0-1000 PPM, ultra-long 10-day standby time in sleep mode, a high-accuracy UK DDS sensor for rapid response, and both audible and visual alerts. Its durable ABS rubber construction and compact design make it suitable for home, travel, and outdoor use.

2. Setup
2.1 Initial Charging
Before first use, fully charge the AGT-3000 using the provided Type-C charging cable. The device is equipped with a rechargeable battery, eliminating the need for disposable batteries.
2.2 Power On and Calibration
To power on the device, press and hold the power button. The device will perform a brief self-test and calibration sequence, indicated by a countdown on the screen. Once complete, it will display '0 PPM' in a clean air environment.
2.3 Testing Before Use
It is recommended to test the detector's functionality before relying on it for safety. You can perform a simple test using a controlled source of combustion:
- Test with Cigarette Smoke: Briefly expose the sensor to cigarette smoke. The PPM reading should increase.
- Test with Paper Burning in Low-Oxygen Conditions: Carefully burn a small piece of paper in a confined, low-oxygen area (e.g., under a glass jar) and expose the sensor to the smoke. The PPM reading should increase significantly.

3. Operating Instructions
3.1 Power On/Off
- To Power On: Press and hold the power button until the screen illuminates.
- To Power Off: Press and hold the power button until the screen turns off.
3.2 CO Level Display
The device continuously monitors carbon monoxide levels and displays them in Parts Per Million (PPM) on the screen. The detection range is 0-1000 PPM.

3.3 Audible and Visual Alerts
When the CO concentration reaches or exceeds the alarm threshold, the device will activate both an audible alarm and a flashing indicator light bar. This dual warning system ensures immediate awareness of potential danger.

3.4 Flashlight Function
The AGT-3000 includes a built-in emergency flashlight with an SOS mode for added utility in low-light conditions or emergencies.

3.5 Sleep Mode
In sleep mode, the device conserves power efficiently, supporting up to 10 days of continuous use while still monitoring CO levels.

4. Maintenance
4.1 Charging
Recharge the device using the Type-C port when the battery indicator shows low power. A full charge ensures optimal performance and standby time.
4.2 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.
4.3 Durability
The AGT-3000 is constructed from premium ABS rubber, offering strong resistance to wear and impact. While durable, avoid unnecessary drops or harsh treatment to prolong its lifespan.

5. Troubleshooting
- Device not turning on: Ensure the device is fully charged. Connect it to a power source using the Type-C cable.
- No CO reading in suspected area: Verify the device is powered on and calibrated. Ensure the sensor is not obstructed.
- False alarms: Move the device to a well-ventilated area. If the alarm persists, contact customer support.
- Screen not responding: Try restarting the device. If the issue continues, contact customer support.
6. Safety Information
6.1 About Carbon Monoxide (CO)
Carbon monoxide (CO) is a colorless, tasteless, odorless toxic gas. Because it is difficult to detect, it is often referred to as the "invisible killer." Inhaling high concentrations can pose serious health risks and even lead to death.

6.2 Potential Sources of Carbon Monoxide
Be aware of potential CO sources in your environment:
- Fireplaces
- Water heaters
- Gas stoves
- Barbecue grills
- Portable heaters
- Car exhaust
Note: The above sources do not necessarily produce carbon monoxide, but can if not properly maintained or ventilated.

6.3 Dangers of Carbon Monoxide Exposure
Symptoms of CO poisoning can include:
- Headache
- Nausea
- Dizziness
- Nerve Damage
- Unconsciousness
