## Long description

DEFENDER OVERLORD GM-890 is a wired optical mouse with a 3200 DPI sensor and six buttons, designed for precise cursor control and responsive input.

How to use
Connect the DEFENDER OVERLORD GM-890 to a free USB Type-A port on your computer and allow the operating system to detect the device; no additional drivers are required for standard pointer and button functions. Position the mouse on a flat, stable surface and adjust grip to rest on the rubber side supports for improved control. Use the DPI adjustment (if available on the device) to change sensitivity according to the task: lower DPI for precise editing and higher DPI for fast cursor movement. The scroll wheel and additional buttons operate as typical mouse controls in most applications and games.
Usage recommendations
For best performance, use the mouse on a clean, non-reflective mouse pad or desktop surface; periodically clean the optical sensor area and cable to prevent dust accumulation. When using gaming titles, test different DPI settings to find the balance between speed and precision. Ensure the USB port provides stable power and avoid excessive cable tension to prolong device lifespan.
