How to use

Choose a connection mode that matches your device. For Bluetooth, enable pairing in your device settings and follow the keyboard’s Bluetooth pairing sequence. For 2.4 GHz wireless, plug the included USB receiver into your computer’s USB port for plug‑and‑play operation. For a wired connection, attach the USB cable to the keyboard and your device. Use the keyboard’s backlight controls to adjust illumination levels as needed and refer to the Keychron key legend or manual for switch and lighting shortcuts.

Recommendations

Ensure the keyboard is charged or connected to power when using the backlight at higher brightness. Keep the 2.4 GHz USB receiver unobstructed and within range for stable wireless performance, and switch to wired mode for tasks that require the lowest latency.
