Customizing Key Functions
The primary advantage of this keyboard is its extensive customization capabilities. Use the dedicated setting program (downloaded during setup) to configure each key.
Supported Function Modes:
- Default Mode: Standard keyboard key input.
- Multimedia Control: Assign keys for media playback (play/pause, next/previous track, volume up/down/mute).
- Two-step Operation: Configure a key to perform one action when pressed and another when released.
- LED Control: Control the keyboard's LED lighting to a specified state or pattern.
- Game Controller: Set keys to act as game controller buttons.
- Key Password: One-key input for a preset password or text string.
- Macro Functions: Program complex sequences of key presses and releases.
- Layered Functions: The software allows for multiple "layers" of key bindings, significantly expanding the number of available functions (e.g., 6 keys x 5 layers = 30 macros).
Steps for Customization:
- Ensure the keyboard is connected to your computer.
- Launch the SayoDevice setting program (or access the web-based tool).
- Select the key you wish to configure.
- Choose the desired function mode and assign the specific action (e.g., assign "Ctrl+C" for copy, "Volume Up" for multimedia control).
- Save the settings. The configurations are stored directly on the keyboard's onboard memory.

Maintenance
- Cleaning: Use a soft, dry cloth to wipe the surface of the keyboard. For deeper cleaning, you may use a slightly damp cloth, ensuring no liquid enters the internal components. Avoid harsh chemicals or abrasive cleaners.
- Keycap Removal: Keycaps can be removed for cleaning or replacement. Gently pull them straight up. Be careful not to damage the mechanical switches underneath.
- Storage: Store the keyboard in a cool, dry place away from direct sunlight and extreme temperatures when not in use for extended periods.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Keyboard not recognized by computer. | Loose USB connection; faulty USB port; incompatible operating system. | Ensure the USB cable is securely connected to both the keyboard and the computer. Try a different USB port. Verify your operating system is supported (Windows, Linux, MacOS, Android, Raspberry Pi). Try restarting your computer. |
| Custom functions not working. | Settings not saved; incorrect configuration in software; software not running (if required for certain functions). | Ensure you have saved the settings in the customization software. Re-check the key assignments in the software. Some complex macros might require the software to be running in the background. Ensure you are using the correct and latest version of the software. |
| Keys feel unresponsive or sticky. | Dust or debris under keycaps; worn-out switch. | Remove the keycap and clean around the switch with compressed air. If the issue persists, the switch may be faulty. (Note: Switches are soldered on and not easily replaceable by end-users). |
| LED lighting not working or incorrect. | LED control settings incorrect; hardware issue. | Check the LED control settings in the customization software. Ensure the LED mode is enabled and configured as desired. |
