Modifying keys to extend functionality:

When the keyboard is connected via USB after entering the webpage above, you can click on "Search FiiO device" to discover the keyboard device.

Main interface of the FiiO multimedia keyboard control program.

1. Function setting bar, to select the key value setting, light setting etc.

2. Three home buttons, corresponding to the three physical keys on KB1, The default function is previous track, play/pause, next track

3. The knob is also a button, turn right for clockwise, left for counterclockwise. Factory default is volume + clockwise, volume - counterclockwise. Vertically press the button, factory default is press to mute.

4. Key layers, which allows multiple layers of key functions to be set.

5. Keyboard name, the users can self-define the name.

Key values setting:

1. Each key of the FiiO multimedia keyboard can be set individually, click on the corresponding key that needs to be set and the key editing interface will automatically pop up.

2. Firstly, enter the mode, select the type of key to be changed. KB1 offers a rich selection of key types, such as normal key value, multimedia, mouse mode, auto-strike, combo continuous strike, one-touch password, and various one-touch multi-character, etc. Users can expand a wealth of interesting usage scenarios according their needs and usage habits.

Multi-layer key setting:

1. The FiiO multimedia keyboard KB1 has 6 keys and knobs, but in practice we can set it in multiple layers to maximize the use of the KB1 for more functional operations, so it can be said that One produced two,two produced three,three produced all things

2. To implement a multi-layer key function setting, you can start by defining one of the keys or knobs of KB1 as the layer switching key. Here I give an example, I am setting the press key of the knob as the level switching key.

3. First click on the press button of the knob in the basic layer, select "SW" in the mode and "Layer 1" in the selection button layer.

4. Then in the first layer Fn1, set the corresponding key function, here I set the 3 main keys as screen brightness adjustment and screen cut off key, very practical.

5. Then set the knob's press key to "SW", and select "Layer 2" in the selection layer, then press the knob's middle key in layer 1 to jump to layer 2, Fn2. The Fn2, Fn3 and "SW" in the Fn4 layer can be set to "Layer 0" to go back to the basic layer, so that the function keys can be switched quickly between layers.

Save the settings:

1. After settings, you can click the ‘Save’ button in the upper right corner, and the Save button will turn gray to indicate a successful save.

2. The FiiO Multimedia Keyboard KB1 has a wealth of expanded features and can be used with computers and desktop/portable players for a better experience. You may want to get your hands on a FiiO Multimedia Keyboard KB1 to enrich your fun music experience.
