Controller Pairing Guide

Check that the red status LED is blinking, which confirms Bluetooth pairing mode is enabled.

Put your controller in pairing mode. Place the controller near the receiver, and ensure all analog sticks and triggers are centered at their neutral positions.
Pairing succeeds once the controller’s light stops flashing, the receiver’s red LED turns off, and the blue power LED stays lit steadily.
