@ufuk -

I am the previous owner of this machine. Do I need to do anything to transfer the warranty to the new owner? I did not register it, and purchased it new from Novamusik in February of this year. I still have the original receipt.

He said his A4 makes a similar noise, just quieter. Like it may be the trig buttons jiggling around or something. But understandably he wants to play it safe.
