- Fn + Arrow Keys: Adjust RGB lighting effects (brightness, speed, mode).
- Fn + Other Keys: Access various system or keyboard-specific functions. Refer to the keycap legends for details.
2. RGB Lighting Control
The keyboard features customizable RGB backlighting and side lighting. Use the following combinations to adjust:
- Fn + \ |: Cycle through different lighting modes.
- Fn + ↑ / ↓: Adjust backlight brightness.
- Fn + ← / →: Adjust lighting effect speed or direction.
- Fn + Del: Change backlight color (for static modes).

Maintenance
1. Cleaning the Keyboard
- Disconnect the keyboard from all power sources before cleaning.
- Use a soft brush or compressed air to remove dust and debris from between the keycaps.
- For stubborn dirt, gently wipe the keycaps and chassis with a slightly damp, lint-free cloth. Avoid excessive moisture.
- Do not use harsh chemicals or abrasive materials.
2. Hot-Swapping Switches
The F108 keyboard features hot-swappable sockets, allowing you to change switches without soldering. This model comes with Roseveil Silent Keyboard Switches.

Figure 5: Demonstrates the hot-swappable feature, showing a switch being removed with a puller, and components like tuned stabilizers and MX Cherry keycaps.
- Removing a Switch: Use the provided switch puller. Grip the switch firmly on the top and bottom (or sides, depending on the puller design) and pull straight up with gentle force. Avoid bending the pins.
- Installing a Switch: Align the pins of the new 3-pin or 5-pin mechanical switch with the holes on the PCB. Gently push the switch down until it clicks into place. Ensure the pins are straight before insertion to prevent damage.
