The wireless connection is extremely easy. The USB receiver is located on the back of the mouse. You just need to switch it to "NO" (please ignore this step if there is no on-off switch). Then, insert the receiver into the USB port of your computer, and give it a few seconds for automatic installation. With a reliable wireless connection, the stable 2.4GHz wireless technology provides a powerful and dependable connection, reaching up to 33 feet without any latency. This allows you to use your computer remotely. It also enables quick reconnection, automatic sleep mode, and energy conservation.
