Operating Instructions

Initial Boot and Operating System

Upon first power-on, the Mini PC will typically guide you through the initial setup of the pre-installed operating system (e.g., Windows 11 Pro). Follow the on-screen prompts to configure language, region, network, and user accounts.

Connecting to Networks

  • Wired Connection: Plug an Ethernet cable into the RJ45 port. The system should automatically detect and connect to the network.
  • Wireless Connection: Access the network settings in your operating system, select your desired Wi-Fi network, and enter the password if required. The device supports WiFi 5 (802.11ac) for stable wireless connectivity.

Display Configuration

The MeLE Quieter3C supports triple display output. You can connect monitors via the two HDMI 2.0 ports and one full-function USB Type-C port. To configure multiple displays, access your operating system's display settings (e.g., right-click on the desktop in Windows and select "Display settings").

Storage Expansion

The device comes with 256GB eMMC storage. For additional storage, you can:

  • Micro SD Card: Insert a Micro SD card into the dedicated slot. It supports up to 1TB.
  • M.2 NVMe SSD: The Mini PC includes an internal M key PCIe 3.0 x2 M.2 SSD NVMe 2280 slot, supporting up to 4TB. This requires opening the device and installing an M.2 SSD (not compatible with SATA interface). Refer to the detailed installation guide for this procedure if available, or seek professional assistance.

Thermal Management

The MeLE Quieter3C features an elegant fanless cooling design, ensuring silent operation and dust resistance. This passive cooling system prevents overheating and supports 24/7 operation. Due to the fanless nature, the surface temperature of the device may reach between 55°C to 70°C during operation. This is normal for fanless mini PCs and meets the safety standards of International Electrotechnical IEC62368-1:2018. Ensure adequate airflow around the device and avoid placing it in enclosed spaces to optimize heat dissipation.

Troubleshooting

  • No Power:
    • Ensure the power adapter is securely connected to both the Mini PC and a working power outlet.
    • If using USB-C PD, verify the power supply provides over 24W and the cable is fully functional.
    • Try a different power outlet.
  • No Display Output:
    • Check all HDMI and USB-C display cables are securely connected to both the Mini PC and the monitor.
    • Ensure the monitor is powered on and set to the correct input source.
    • Test with a single monitor and cable to isolate the issue.
  • No Internet Connection:
    • For wired connections, ensure the Ethernet cable is properly connected and your router is functioning.
    • For Wi-Fi, check your network settings, ensure Wi-Fi is enabled, and re-enter the password if necessary. Restart your router if other devices are also experiencing issues.
  • System Slowdown/Overheating:
    • While the device is fanless, ensure it is placed in a well-ventilated area and not in an enclosed space.
    • Close unnecessary applications to reduce CPU load.
    • Monitor ambient temperature; extreme heat can affect performance.

Maintenance

  • Cleaning: Use a soft, dry cloth to clean the exterior of the Mini PC. Avoid liquid cleaners directly on the device. The fanless design reduces dust accumulation internally, but external vents should be kept clear.
  • Software Updates: Regularly update your operating system and drivers to ensure optimal performance and security.
  • Storage Management: Periodically check your storage usage and remove unnecessary files to maintain system responsiveness.
  • Environmental Conditions: Operate the Mini PC within recommended temperature and humidity ranges. Avoid direct sunlight and extreme temperatures.
