The most obvious feature that the Wireless Intellimouse Explorer boasts is its wireless connectivity. This is great for people who need to reduce desktop clutter because it removes unnecessary cabling. The mouse comes with a small radio receiver that connects to the USB port of your PC. The two channel radio frequency allows you to place the receiver out of sight, and having two channels means that in the rare instance of interference from another device you can simply switch channels to continue working unimpeded. You are also able to operate the mouse from up to 6ft away from the receiver. In the image below you will notice a small button on the top of the receiver. If you have lost the connection between the receiver and the mouse, all you have to do is press this button and the green LED on the receiver should start blinking. Once this happens, you need to press a small button located at the bottom of the mouse and you are able to continue working. To ensure that the receiver does not slide around on the table, it is held in place by three rubber feet on its underside.
Replacing the mouse ball is an optical sensor, dubbed the "Intellieye". As the mouse moves, the optical sensor takes pictures of the mousing surface. This is how the mouse detects movement. Competing optical mice can only take a maximum of 2,500 pictures per second however, the Wireless Intellimouse Explorer can take an awesome 6,000 pictures per second, resulting in much more accurate cursor movement. You are also able to use the mouse on almost any surface, with the only exception being reflective surfaces and glass.
