If your SCUF Omega is not registering on your PlayStation you may want to try the following.
1 Manual Reset Button: Remove the faceplate and locate the small hole below the Circle Button. Press the button inside using a paper clip to recover the controller if it becomes stuck.
2 Reconnect: Unplug the wireless receiver from your PlayStation and plug it back in. You may try different USB ports.
3 PlayStation Mode: Remove the faceplate and locate the Platform switch. Ensure this is set to PS5.
4 Dongle Overheating: Is the wireless dongle at the rear of your console with poor airflow? If so lets give the receiver more room to breath by moving the console to an open space.
5 Soft Reset: Turn off the controller, then press and hold 'X' + 'PS Button' for 5 seconds until it starts back up. This restores factory settings for profiles, mappings, and calibration.
6 Hard Reset: Turn off the controller, then press and hold 'Circle' + 'Triangle' + 'PS Button' for 5 seconds. This restores all out-of-the-box settings, including pairing data.
