How to use

For Bluetooth mode, enable Bluetooth on your device and follow the device’s pairing procedure to connect to the keyboard; consult your host device’s Bluetooth settings to manage connections and switch between paired devices. Use the keyboard’s mode switch or function keys (if present) to change between Bluetooth and 2.4 GHz operation.

Usage recommendations

Place the USB receiver close to the keyboard when using 2.4 GHz mode to maintain stable signal, and keep the keyboard within the typical Bluetooth range (about 10 meters) when paired via Bluetooth. Turn off the keyboard when not in use to extend battery life and avoid placing it near strong radio-frequency sources to reduce interference.
