How to use

To use the mouse, insert the 2.4 GHz USB receiver into an available USB port or enable Bluetooth on the target device and pair according to the device pairing procedure. Switch between connectivity modes using the mode selector if present on the underside of the mouse. Install batteries or charge the internal battery as required before first use. Position the mouse on a flat surface and move it to control the on-screen pointer; use the additional buttons and scroll wheel to navigate documents and web pages.

Usage recommendations

For best tracking performance, use the mouse on a clean, non-reflective surface or a mouse pad; keep firmware or driver updates applied where available. In shared environments, prefer Bluetooth for devices without spare USB ports and switch to the 2.4 GHz receiver when lower latency is needed, such as in intensive navigation tasks.
