How to use

Connect the keyboard to a computer or device using the supplied USB cable for wired operation and firmware-level polling performance. For wireless use, pair the keyboard via Bluetooth following the device’s Bluetooth pairing procedure and switch to the desired device profile. Adjust the LED backlight brightness or modes using the keyboard’s built-in key combinations. Use the Launcher or QMK tooling where available to remap keys, customize layers, and create macros for workflows that require additional personalization.

Recommendations

For stable performance during gaming or latency-sensitive tasks, prefer wired USB mode. Use Bluetooth mode for convenience when working across multiple devices. Keep keycaps and the keyboard surface free from dust and liquid; clean gently with a dry or slightly damp microfiber cloth. If available, use the Keychron Launcher or QMK firmware to configure separate keymaps for macOS and Windows and to tailor backlight settings to your environment.
