4. Mga Instruksyon sa Pag-opera
4.1 Pag-on
Press the power button located on the front I/O panel to turn on your computer.
4.2 ARGB nga Pagkontrol sa Kahayag
The DS900 supports Addressable RGB (ARGB) lighting. If your motherboard has a 5V 3-pin ARGB header, you can connect the case's ARGB cables to it and control the lighting effects via your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync). If your motherboard does not have an ARGB header, an external ARGB controller (not included) may be required for lighting control.
4.3 Front I/O Ports
The front I/O panel provides convenient access to:
- 1x USB 3.0 port
- 2x USB 2.0 nga mga pantalan
- HD Audio (headphone and microphone jacks)
- Butang sa Gahum
- I-reset ang Butang
5. Pagmentinar
Ang regular nga pagmentinar makatabang sa pagsiguro sa labing maayo nga performance ug taas nga kinabuhi sa mga component sa imong PC.
5.1 Dust Filters
The DS900 is equipped with removable dust filters on the top and bottom. Periodically remove and clean these filters to prevent dust buildup inside the case, which can hinder airflow and component cooling.
- Gently slide out the filters.
- Clean them with a soft brush or rinse with water (ensure they are completely dry before reinstallation).
5.2 Tempered Glass Panels
Clean the tempered glass panels with a microfiber cloth and a non-abrasive glass cleaner. Avoid harsh chemicals that could damage the glass or coatings.
5.3 Paglimpyo sa Sulod
Occasionally, use compressed air to blow out dust from inside the case, especially around fans, heatsinks, and other components. Ensure the system is powered off and unplugged before cleaning.
6. Pagsulbad sa problema
Here are some common issues and potential solutions:
- PC does not power on:
- Check if the PSU is properly connected to the wall outlet and switched on.
- Siguruha nga ang tanang kable sa kuryente (24-pin ATX, 8-pin CPU, PCIe power) lig-on nga nakakonekta sa motherboard ug mga component.
- Verify the front panel power switch cable is correctly connected to the motherboard header.
- Fans are not spinning:
- Check if fan cables are securely connected to the motherboard fan headers or a fan controller.
- Ensure the PSU is providing power.
- ARGB lighting is not working:
- Verify the ARGB cable is correctly connected to a 5V 3-pin ARGB header on your motherboard (not a 12V 4-pin RGB header).
- Ensure your motherboard's RGB software is installed and configured correctly.
- If using an external controller, check its power and connections.
