2. Safety Information

WARNING: This device is intended to detect carbon monoxide gas. It is not a substitute for proper maintenance of fuel-burning appliances, including ventilation systems, nor is it a substitute for visual inspection of such appliances. Carbon monoxide is a colorless, odorless, and non-irritating gas that can be fatal.

• Do not block the ventilation holes on the device.
• Do not expose the device to extreme temperatures or humidity.
• Keep the device away from direct flame or heat sources.
• Do not attempt to disassemble or repair the device. Contact customer support if service is required.
• Test the device regularly as described in this manual.

Familiarize yourself with the symptoms of carbon monoxide poisoning:

• Mild Exposure: Slight headache, nausea, vomiting, fatigue (often described as 'flu-like' symptoms).
• Medium Exposure: Severe headache, dizziness, drowsiness, confusion.
• Extreme Exposure: Unconsciousness, convulsions, cardiorespiratory failure, death.

If the alarm sounds, immediately move to fresh air and seek medical attention. Do not re-enter the area until the source of CO has been identified and corrected, and the area has been properly ventilated.

5.4 Testing the Detector

To verify the CO detection function, expose the device to a small amount of carbon monoxide. A common method is to bring it close to a lit cigarette or burning paper that produces thick smoke. The CO concentration on the screen should increase, and the alarm should activate if levels exceed the threshold. Do not test with car exhaust or in overly airy places, as low CO concentrations may not trigger the sensor.

6. Alarm Information

The HAKINAKU HD09 features an electrochemical sensor for accurate CO detection and an 85dB alarm to alert users to dangerous levels. The alarm behavior varies based on CO concentration:

Upon alarm activation, follow the safety procedures outlined in Section 2.

7. Placement and Usage Scenarios

The portable design of the HD09 makes it suitable for various indoor and outdoor environments where carbon monoxide monitoring is crucial.

• Travel: Ideal for hotel rooms, rental properties, or temporary accommodations.
• Camping & Outdoor Activities: Monitor CO levels in tents, RVs, boats, or near portable heaters/stoves.
