Bedienungsanleitung
1. Einschalten
After all components are securely installed and cables are connected, close all panels. Connect your monitor, keyboard, mouse, and power cable to the PSU. Press the power button on the top I/O panel to start your system.
2. RGB-Beleuchtungssteuerung
The pre-installed ARGB fans can be controlled via the dedicated LED control buttons (M & C) on the front I/O panel. The 'M' button cycles through various lighting modes, while the 'C' button changes colors within a mode. Alternatively, if connected to a compatible motherboard's ARGB header, you can synchronize the lighting with your motherboard's software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion, ASRock Polychrome Sync).
Wartung
1. Reinigung des Staubfilters
To maintain optimal airflow and prevent dust buildup, regularly clean the magnetic dust filters:
- Top-Filter: Easily removable magnetic filter on the top panel.
- Front Panel Filter: Located behind the mesh front panel, also magnetic.
- Bodenfilter: A tray-style filter located under the PSU chamber, slides out from the rear.
Gently remove the filters and clean them with a soft brush or by rinsing with water (ensure they are completely dry before re-installing).
2. Allgemeine Reinigung
For the exterior, use a soft, damp cloth to wipe down surfaces. For the tempered glass panels, use a glass cleaner and a microfiber cloth. Avoid abrasive cleaners or solvents that could damage the finish.
Fehlerbehebung
If you encounter issues with your LANCOOL II Mesh RGB case, consider the following common troubleshooting steps:
- System schaltet sich nicht ein:
- Ensure the PSU is properly seated and secured.
- Verify all power cables (24-pin ATX, CPU, GPU, SATA) are firmly connected to the motherboard, components, and PSU.
- Prüfen Sie, ob das Kabel des Netzschalters an der Vorderseite korrekt an den Frontpanel-Anschluss des Motherboards angeschlossen ist.
- Confirm the PSU's power switch is in the 'ON' position.
- Lüfter drehen sich nicht / RGB-Beleuchtung funktioniert nicht:
- Check that the fan power cables are securely connected to the motherboard or fan controller.
- Ensure the ARGB cables are properly connected to the motherboard's ARGB header or the case's integrated RGB controller.
- If using motherboard software for RGB control, ensure the software is installed and configured correctly.
- Poor Airflow / High Temperatures:
- Reinigen Sie alle Staubfilter regelmäßig.
- Verify that fans are installed with the correct airflow direction (intake for front/bottom, exhaust for rear/top).
- Stellen Sie sicher, dass keine Kabel die Luftzirkulation im Inneren des Gehäuses behindern.
For persistent issues, consult your motherboard's manual for specific header layouts and power connections, or visit the Lian Li support webWebsite.
