You can download Receiver Manager for the x010 models here: (link
The file is called RX-Ax010_ReceiverManager_1_01.zip.
The documentation included is for an older version, but not much has changed. Basically you want to run it in Async mode, select your model, then press Upload to upload your current settings to your PC. Be careful not to press Download instead because that overwrites your current settings in the receiver.
Afer uploading the settings, use the File menu to save them on the PC.
To restore, just Open the file you saved, then Download to the receiver.
I've never used this version myself as I don't have an A-series model, but I think it should be able to find your 3010 on the network automatically. If not, maybe someone who's already used Receiver Manager can comment.
