Mouse A4tech G3-280N V-Track Wireless Optical 1200 DPI 2.4GHz Grey

The A4tech G3-280N V-Track Wireless Optical 1200 DPI 2.4GHz Grey is a cordless computer mouse designed for everyday desktop and laptop use. It uses V-Track optical sensing to provide consistent pointer control across a variety of surfaces and a 1200 DPI sensitivity setting that balances precision with smooth cursor movement. The mouse communicates over a 2.4 GHz wireless link for a stable connection within typical desk and room ranges and features an ergonomic silhouette with a neutral grey finish suitable for home and office environments.

Advantages

The V-Track optical system improves tracking on textured or reflective surfaces compared with basic optical sensors, reducing pointer jitter. A 1200 DPI sensor provides accurate navigation for standard productivity tasks without requiring frequent sensitivity adjustments. The 2.4 GHz wireless connection delivers plug-and-play operation through a USB receiver and maintains reliable responsiveness across normal working distances. The ergonomic shape supports comfortable use during extended sessions and the compact design is convenient for mobile setups.

How to use

Install a compatible battery, insert the USB wireless receiver into an available USB port on your computer and allow the operating system to detect the device. Place the mouse on a suitable surface and move to verify cursor response. Use the scroll wheel for vertical navigation and the primary and secondary buttons for standard click operations. For battery conservation, turn the mouse off when not in use if an on/off switch is provided, or rely on its automatic power-saving mode if supported.

Usage recommendations

For best tracking performance with the V-Track sensor, use on non-reflective surfaces such as cloth or a standard mouse pad. Replace batteries when cursor response becomes intermittent and keep the USB receiver within line-of-sight range of the mouse to reduce potential interference.
