The YOJOCK HD08 Carbon Monoxide Detector is designed for easy plug-and-play setup.

Dadbacio: Carefully remove the detector from its packaging.
Attach Plug: Ensure the detachable plug is securely locked into the device.
Plygiwch i mewn: Insert the detector into a standard wall outlet. The device will begin a warm-up period (approximately 28 seconds) and then enter monitoring mode.
Lleoliad: For optimal detection, place the detector in a room where CO sources might be present, such as near a furnace, water heater, or in living areas and bedrooms. Avoid placing it directly above heat sources or in areas with high humidity.

Prawf Cychwynnol

It is recommended to perform an initial test after plugging in the device to ensure it is working correctly.

Steps for testing the Carbon Monoxide Detector with a lit incense stick — **Figure 3: How to Test the Detector.** This image shows a two-step process: first, plugging in the CO detector and allowing it to warm up, and second, placing a lit incense stick near the CO sensor to observe the concentration display.

Plug the CO detector into an outlet and wait for approximately 28 seconds to allow it to warm up.
Place a lit incense stick near the CO sensor (located at the bottom). The CO concentration will be detected and displayed shortly.

Nodyn: The detector will show 000 PPM when no CO is detected. When testing near exhaust ducts or stoves, if your car engine or stove is burning cleanly, the detector may continue to display 000 PPM.

Diagram showing button functions for self-test, temperature unit switch, and brightness adjustment — **Figure 5: Easy to Use Button Functions.** This image details the functions of the 'O' button for self-test and temperature unit switching, and the 'H' button for adjusting screen brightness.

'O' Button (Self-Test / Temperature Unit Switch):
- Gwasg Fer: Initiates a self-test. The green light will blink 3 times and 3 beeps will sound if the device is functioning normally.
- Gwasg Hir: Toggles the temperature unit between Celsius (°C) and Fahrenheit (°F).
'H' Button (Screen Brightness): Short press to adjust the screen brightness (Low, High, or Off).
'D' Button (Mute/Unmute Alarm): Short press to mute or unmute the alarm sound.

Alarm Levels and Indicators

Infographic showing 3-stage CO level monitoring: Safe, Warning, and Danger with corresponding visual and audio alerts — **Ffigur 6: 3-Stage CO Level Monitoring.** This infographic explains the different CO concentration levels (Safe, Warning, Danger) and their associated visual (blinking icons) and audio (no alarm, alarm every 2 minutes, continuous alarm) alerts.

Safe (0-50 PPM): Green blinking icon, no audible alarm.
Rhybudd (51-200 PPM): Yellow blinking icon, "Di Di Di" alarm sounds every 2 minutes.
Perygl (201-999 PPM): Red blinking icon, continuous audible alarm. Press the 'D' button to activate or mute the alarm.

Nodyn: When CO levels reach ≥200 PPM, the alarm will sound continuously and cannot be manually silenced until the CO level drops below 200 PPM.

5. cynnal

Glanhau Rheolaidd: Gently wipe the exterior of the detector with a soft, damp brethyn. Peidiwch â defnyddio cemegau llym na glanhawyr sgraffiniol.
Cadwch fentiau'n glir: Ensure the air inlets and vents are free from dust, debris, or obstructions to allow for accurate gas detection.
Hunan-brawf Misol: Perform a self-test at least once a month by short-pressing the 'O' button to confirm proper operation.
Osgoi Amodau Eithafol: Do not expose the detector to extreme temperatures, high humidity, or direct water.

6. Datrys Problemau

Seiniau Larwm: If the alarm sounds, immediately move to fresh air, ventilate the area, and contact emergency services. Do not re-enter the premises until it has been deemed safe by professionals.
Golau Dangosydd Coch: A red blinking indicator light may signal that the CO gas concentration exceeds the standard level, or there is a mute error or sensor failure. Refer to the alarm levels section for specific actions.
No Display/Device Not Responding: Ensure the device is securely plugged into a working outlet. If the issue persists, unplug and re-plug the device.
Inaccurate Temperature/Humidity: Small deviations (±5% / ±5°C) are normal. Readings become more accurate approximately 60 minutes after plugging in.
