Wireless Keyboard and Mouse

These devices that communicate through radio frequencies work on one of two channels. So in a small area only two sets can be used, which may be okay in homes or small offices, but not in offices with many computers kept close to one another. The receiver can be kept almost anywhere, other than near the monitor as it may interfere with the monitor’s magnetic field.

The manual promises that these work within 1.5 m from the receiver, but the keyboard works from almost 4 m and the mouse from about 2 m. Only its not of consequence as you can’t read the text from that distance. It will work for presentations, where you have a large screen. Also, the mouse is prone to being misplaced. Apart from the regular keys, the keyboard has eight other short-cut keys, which you can also program as combination keys. These require IE 5.0 or later, Windows 9x/NT 4.0. Its price of Rs 2,400 is competitive compared to A4Tech’s wireless mouse (reviewed on the previous page).
