Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. You can switch and use four computers with one set of USB keyboard, USB mouse, and display. You can easily switch between the four computers by pressing the [Ctrl] key twice or by pressing [ScrLock] twice + [1 to 4]. It is also possible to switch using the buttons on the front of the main unit, and the switching status can be visually confirmed using the LED. You can switch consoles while the connected computer is turned on. Since the keyboard port is emulated, full startup is possible without switching ports when rebooting. You can lock the switching function (disable the hotkey) by pressing the [Ctrl] key + [F12] key. This product can also be used in games and applications that use the [Ctrl] key in various ways. It is possible to start four connected computers at the same time. It uses an all-in-one connector that combines keyboard, mouse, and display signals into one. Connections are easy and the wiring looks neat. You don't need to install any software; you can switch between them just by connecting them. It operates by supplying power from the computer's USB port, so no AC adapter is required.
