5. Operating Instructions
5.1 Thumb Control Trackball
The primary method of cursor control is the thumb-operated trackball. Use your thumb to roll the ball in any direction to move the cursor on the screen. This design minimizes arm and wrist movement, promoting ergonomic comfort.

5.2 DPI Adjustment
The DPI (Dots Per Inch) button allows you to adjust the cursor sensitivity. Press the DPI button (located on the bottom of the mouse, near the power switch) to cycle through different DPI settings. Higher DPI settings result in faster cursor movement, while lower settings provide more precise control.
5.3 RGB Backlight Control
The mouse features an RGB backlight strip. Use the "Light Switch Button" (located near the scroll wheel) to cycle through various lighting effects or to turn the backlight off. This allows for customization of the mouse's aesthetic to match your setup or preference.
