4.2 Multimedia Functions
The keyboard supports multimedia functionality. Specific key combinations for multimedia controls (e.g., volume, play/pause) are typically accessed via the Fn key in combination with the F-keys or other designated keys. Refer to the keycap legends for specific multimedia shortcuts.
4.3 Anti-Ghosting (All Keys Non-Conflict)
The HXSJ K88 features "all keys non-conflict input," also known as N-key rollover. This ensures that every key press is registered accurately, even when multiple keys are pressed simultaneously, which is crucial for fast typing and gaming.

5. Maintenance and Care
- Cleaning: The keyboard features dual-color injection keycaps, which are durable and resistant to fading. To clean, disconnect the keyboard from your computer. Use a soft, damp cloth to wipe down the keycaps and chassis. For deeper cleaning, you may use compressed air to remove debris from between the keys.
- Spill Resistance: The HXSJ K88 supports waterproofing. While it can withstand minor spills, it is not fully submersible. In case of a spill, immediately disconnect the keyboard, wipe off any liquid, and allow it to air dry completely before reconnecting.
- Cable Care: The detachable USB Type-C cable should be handled with care. Avoid sharp bends or excessive pulling to prevent damage.
- Storage: When not in use, store the keyboard in a clean, dry environment away from extreme temperatures.
6. Troubleshooting
- Keyboard not responding:
- Ensure the USB cable is securely connected to both the keyboard and the computer.
- Try plugging the keyboard into a different USB port on your computer.
- Restart your computer.
- Test the keyboard on another computer to rule out a computer-specific issue.
- Keys not registering or ghosting:
- Ensure the keyboard is clean and free of debris that might be obstructing key switches.
- The K88 features N-key rollover, so ghosting should not be an issue under normal operation. If it persists, try the steps for "Keyboard not responding."
- Backlight not working or stuck:
- Use the Fn + \| key combination to cycle through lighting modes.
- Use Fn + ↑ to increase brightness.
- Ensure the keyboard is properly powered via the USB connection.
