Please try repairing the remote with the unit:
1. Remove the battery cover and with a pin, press the "Pair" button.
2. A red light will appear on the remote near the "Pair" button.
3. White the red light is on, please place the remote next to the Agora Smart TV box while the light is on.
4. The light should then disappear.
This will indicate that the remote is successfully paired with the Agora Smart TV Box, and you will now be able to control the cursor with the remote.
