Current output of the Integrated USB HUB
The 2x USB downstream ports (USB HUB) on the back side supply a current of 100 mA on each port.
Before connecting a USB device to the ports, check that the consumption current of your USB device does not exceed 100 mA or the USB device may not be detected and may not function correctly.

By using the Dip-Switches on the back of the keyboard, you can change the Keyboard Mode and functions of some of the keys on the Keyboard. The HHKB mode is set as the factory default.
Important! Please disconnect the HHKB from the host PC before changing the Dip Switch settings or changes may not be recognised and you may damage the product.

Keyboard Layouts & Settings
Microsoft Windows
To use the HHKB in Windows, go to ‘Regional Settings’, ‘Keyboards & Languages’ tab, click the ‘Change Keyboards’ button and ensure you have the following keyboard installed:
English (United Kingdom): ‘Keyboard – United Kingdom’
French (France): ‘Keyboard – French’
German (Germany): ‘Keyboard – German’
Italian (Italy): ‘Keyboard – Italian’
Spanish (Spain): ‘Keyboard – Spain’
You can use the ‘Add’ button to add the required Keyboard if it is not already installed in Windows.
Japanese Keyboard Settings
If you use the HHKB with the Japanese keyboard setting, you cannot input symbols such as brackets and @ in accordance with the symbols on the keys.
When you connect the keyboard to a laptop computer with a Japanese keyboard and change the keyboard layout setting to the English keyboard, you cannot input symbols in accordance with the symbols on the keys of the laptop computer. This is caused by a feature of the operating system.
Apple macOS
After the dedicated driver for macOS is installed, the [Alt] key works as the [Option] key and the [0] key works as the [Command] key.
To use multimedia keys, press the [Fn] key and one of the following keys at the same time.
