1. Setup Instructions
Follow these steps to quickly set up your PEIOUS Wireless Mouse:

- Power On: Locate the power switch on the underside of the mouse and slide it to the "ON" position.

2. Operating Instructions
2.1 Basic Mouse Functions
The PEIOUS Wireless Mouse operates like a standard computer mouse:
- Left Button: Primary click function.
- Right Button: Secondary click function, typically for context menus.
- Scroll Wheel: Scroll up or down through documents and web pages.
- Forward/Backward Buttons: Located on the side, these buttons allow for quick navigation (e.g., browsing web pages).
2.2 DPI Adjustment
The mouse features adjustable DPI (Dots Per Inch) settings to control cursor sensitivity. Press the DPI button (located near the scroll wheel) to cycle through different sensitivity levels (e.g., 800, 1200, 1600, 2000 DPI). Choose the setting that best suits your preference and task.

2.3 Activating Mouse Jiggler Mode
The built-in mouse jiggler feature prevents your computer from entering sleep mode or locking, keeping your status active during breaks or when away from your desk.
- Activate Jiggler: Press and hold the DPI button for 3-5 seconds. The LED lights on the mouse will turn green, indicating that the jiggler mode is active.
- Deactivate Jiggler: To turn off the jiggler mode, press and hold the DPI button again for 3-5 seconds. The green lights will turn off.

2.4 LED Light Modes
The mouse features dynamic LED lighting. Use the Light Mode Switch on the underside of the mouse to change or turn off the lighting effects.
