## Long description

The Crono CM645 Optical Wired USB Black mouse is a compact, corded pointing device designed for everyday office and home use.

Key specifications
 Connection type: wired USB (plug-and-play)
 Sensor type: optical
 Sensitivity: 1000 DPI
 Design: symmetrical/ergonomic
 Color/finish: black
 Primary controls: left and right buttons, scroll wheel
 Compatibility: standard desktop and laptop operating systems supporting USB mice
How to use
Connect the mouse to an available USB port on your computer; the system should recognize it automatically without additional drivers in most modern operating systems. Place the mouse on a flat, stable surface or use a mouse pad for improved tracking. Adjust pointer speed and button settings in your operating system’s mouse settings if necessary to match your preferred sensitivity and scrolling behavior. For left- or right-hand users, the symmetrical shape allows comfortable positioning of the hand and fingers.
Usage recommendations
For consistent performance, keep the optical sensor area free of dust and debris; periodically wipe the underside with a soft, dry cloth. Use on a non-reflective surface to maintain accurate tracking. If you require higher sensitivity for specific tasks, change pointer speed in software rather than modifying physical hardware. Store the cable without sharp bends to extend its service life.
