The batte­ries are empty

• Check the batte­ries by pres­sing the buttons, the red indi­cator light on the remote control will not light up if the batte­ries are empty.
• Replace the remote control batte­ries.

The remote control is not paired with the power supply

• Pair the remote control with the robotic cleaner power supply.
