How to use

Connect the keyboard with the included USB Type-C cable for wired use and charging. For wireless operation, pair via Bluetooth 5.1 with your device or switch to the RF wireless mode if you use a compatible receiver. Adjust backlight brightness and effects using the keyboard’s built-in controls. Charge the keyboard via the USB Type-C port when battery level is low; the rechargeable battery provides long runtimes but charging frequency depends on backlight intensity and connectivity mode.

Recommendations

For longest battery life, disable or reduce backlight brightness when not needed and use Bluetooth mode when RF is not required. Keep firmware and device drivers updated for best compatibility across operating systems. Use the wired USB connection for low-latency applications such as competitive gaming or when charging while playing.
