Bluetooth Mode: To enter Bluetooth pairing mode, press and hold the FN+1, FN+2, or FN+3 key combination for 3 seconds. The corresponding 1/2/3 indicator will flash quickly, indicating pairing mode.

2.4G Mode: To activate 2.4G wireless mode, press and hold the FN+4 key combination for 3 seconds. The indicator light will flash quickly. Insert the 2.4G dongle into your computer. The keyboard will exit pairing mode after a successful connection. If a paired device is not found within 30 seconds, the indicator light will turn off, and the keyboard will go to sleep.

Wired Mode: To switch to wired mode, press and hold the FN+5 key combination for 3 seconds. Connect the keyboard to your device using a USB cable.

Maintenance Features
