Sejin’s wireless Keyboards with and without built in mouse-function are quality products. They have a very pleasant keytouch and a amazing mouse response. The nominal operating range is 5 meters, but they will work up to 13 meters with fresh batteries.
The wireless Keyboards work the same way as a remote control for a TV. Infra Red Light ( IR ) is transmitted to an IR- receiver. The receiver plugs into the computer in the same PS/2 ports that are used for the ordinary keyboard and mouse. It is entirely ”Plug and Play” and no software is needed.
With more users in the same room you individualise the Keyboards with special ID-function allowing up to 16 individual keyboards to be used in the same room.

Liberated from the wires

Liberated from the wires to Keyboard and Mouse you will work more relaxed and comfortable.

Stow the Keyboard wherever you like to get more space on your desk.

You will allow yourself a more ergonomic working position and you reduce the risk of getting a ”mouse-arm” and stiff neck.
