Operating Instructions
Ergonomic Design
The vertical design of this mouse promotes a natural "handshake" posture, which helps to alleviate pressure in the wrist joint and reduces the risk of cramping and discomfort during prolonged computer use.

DPI Adjustment
The mouse features a dedicated DPI button, allowing you to switch between three sensitivity levels: 800, 1200, and 1600 DPI. Press the DPI button (located near the scroll wheel) to cycle through these settings and find the precision that best suits your task.
Multi-functional Buttons
In addition to the standard left and right click buttons and scroll wheel, the mouse includes forward and back buttons located on the side. These buttons enhance navigation in web browsers and file explorers. Note: Forward/back buttons are not compatible with Mac OS.
Auto-Sleep Function
To conserve battery life, the mouse will automatically enter sleep mode after 7 minutes of inactivity. To wake the mouse, simply click any button.
