2. Connecting the USB Wireless Receiver
Locate the USB wireless receiver (dongle) included in the package. Insert this dongle into an available USB port on your target device (Smart TV, PC, Android TV Box, etc.). The device should automatically recognize the receiver and install necessary drivers (Plug and Play functionality).

If pairing is unsuccessful, press the "OK" key and the "TV" key on the remote simultaneously. This should re-initiate the pairing process.

- Click the key on the Rii MX3 (e.g., one of the color keys) that you wish to program. The LED light will become slow flashing, meaning the Rii MX3 has received the code values.
- After successful learning, you can press the TV button to exit the learning mode. The LED will stop lighting. This procedure can be repeated for other programmable keys.

Troubleshooting
Universal Controller Limitations
As a universal controller, it is normal that some keys or functions might not be fully compatible or applicable to all devices. This is due to variations in operating systems and device-specific configurations. If a particular function does not work as expected, it may be a limitation of the device's compatibility rather than a defect of the Rii MX3.
