- 2.4GHz Wireless:
For 2.4GHz wireless connection, plug the USB dongle (typically stored in the keyboard's battery compartment or a dedicated slot) into an available USB port on your device. Switch the keyboard's mode selector to "2.4G". The keyboard should automatically connect, providing a swift 1000 Hz polling rate for responsive performance.
- Bluetooth 5.2:
To connect via Bluetooth, switch the keyboard's mode selector to "BT". On your device (computer, tablet, or phone), enable Bluetooth and search for new devices. Select "Keychron B6 Pro" from the list of available devices to pair. The keyboard supports seamless switching between multiple paired Bluetooth devices (refer to operating instructions for details).
- Wired USB Type-C:
For a wired connection, switch the keyboard's mode selector to "Cable". Connect the USB Type-C cable from the keyboard to a USB port on your device. The keyboard will function as a wired device and charge simultaneously.
3. Operating System Compatibility
The Keychron B6 Pro is designed with a Mac layout but is fully compatible with Windows operating systems. A dedicated switch on the side of the keyboard allows you to toggle between Mac and Windows modes, ensuring correct key mapping without needing to change keycaps.
Operating Instructions
1. Basic Key Functions
The keyboard features a standard full-size layout with a numeric keypad. All keys function as labeled. The top row includes function keys (F1-F12) which often double as media control keys or system shortcuts when pressed in combination with the 'Fn' key.

Maintenance
1. Cleaning the Keyboard
To maintain optimal performance and appearance, regularly clean your keyboard. Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution. Avoid excessive moisture. For cleaning between keycaps, use compressed air or a small brush.
2. Using the Protective Silicone Skin
The Keychron B6 Pro includes a protective silicone skin. This skin is designed to fit each key individually, enhancing typing comfort and guarding against spills, dust, and debris. The silicone skin is washable and reusable, contributing to the longevity and cleanliness of your keyboard.
