Setup

1. Initial Charging

Before first use, fully charge the detector using the provided Type-C USB cable. Connect the cable to the device's Type-C port and a standard USB power adapter (not included). The battery icon on the display will indicate charging status.

2. Power On/Off

• To Power Off: Long press the power button until the display turns off.

Operating Instructions

1. Display Information

Upon powering on, the 1.9" HD color display will show:

• CO Concentration: Displayed in Parts Per Million (PPM).
• Humidity: Displayed as a percentage (RH).
• Temperature: Displayed in Fahrenheit (°F) or Celsius (°C).
• Battery Level: An icon indicating the current battery charge.
• Alarm Status: An icon indicating if the audible alarm is active.

2. Changing Temperature Units

Short press the power button (central button) to toggle between Fahrenheit (°F) and Celsius (°C) temperature display.

3. Adjusting Screen Brightness

Short press the 'M' button (left button) to cycle through different screen brightness levels.

4. Alarm Sound Control

Short press the 'S' button (right button) to toggle the audible alarm sound on or off. The speaker icon on the display indicates the current status.

5. Power-Save Mode

The screen backlight will automatically turn off after 30-60 seconds of no operation or alarm signal to conserve battery. The detector continues to monitor CO every 2 seconds. Press any button to reactivate the backlight.

CO Alarm Thresholds

Testing the Detector

To ensure the carbon monoxide detector is functioning correctly, you can perform a simple test:

1. Light a piece of paper or a cigarette.
2. Extinguish the flame, allowing it to produce thick smoke.
3. Hold the detector close to the smoke for 5-10 seconds, allowing the smoke to enter the ventilation holes.
4. The CO concentration on the screen should increase, and the detector will sound an audible alarm if the concentration exceeds the threshold.

Note: Do not test with car exhaust or in overly airy places, as low CO concentrations may not trigger the sensor.

Placement Guidelines

The HAKINAKU D6 is designed for portability and can be used in various indoor and outdoor environments. Consider placing it in areas where CO may accumulate or where you need to monitor air quality.

• Travel: Hotels, Airbnb, RVs, camping tents, boats, aircraft.
• Home: Bedrooms, living rooms, kitchens (away from direct cooking fumes), areas with fuel-burning appliances.
• Work: Offices, warehouses, workshops.

Maintenance

1. Charging

When the battery is low, the detector will sound an audible 'di' every minute. Recharge the device using the provided Type-C cable. The device can operate while charging.

2. Cleaning

Wipe the exterior of the detector with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the ventilation holes are clear of dust and debris.

Troubleshooting

• No Display/Device Not Turning On: Ensure the device is fully charged. Long press the power button to turn it on.
• Inaccurate Readings: Ensure the ventilation holes are not obstructed. Avoid placing the detector in areas with extreme temperatures or humidity, or near strong air currents.
• Alarm Sounds Continuously: If the alarm sounds without a known CO source, move the detector to a well-ventilated area. If the alarm persists, contact customer support.
• Low Battery Alert: Recharge the device promptly.

Safety Information

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be fatal. It is produced by incomplete combustion of carbon-containing materials. Always be aware of potential CO sources.

Symptoms of CO Poisoning:

• Mild exposure: Mild headache, nausea, vomiting, fatigue (often mistaken for flu-like symptoms).
• Medium exposure: Severe headache, dizziness, drowsiness, confusion.
• Extreme exposure: Unconsciousness, convulsions, cardiorespiratory failure, death.

If the detector alarms, immediately move to fresh air and seek medical attention. Do not ignore the alarm.

Warranty and Support

The HAKINAKU D6 Carbon Monoxide Detector comes with a 5-year free exchange warranty for any quality issues. Customer satisfaction is a primary goal. If you encounter any problems or have questions regarding your product, please contact customer support for assistance.
