E06 error on a LS-WV2.0TL/R1

[capins]

I have an old LS-WV2.0TL/R1. After a disk changing starts blinking the E06 error. I try to:
- change/remove disks;
- restore defaul settings with the FUNCTION button on the bottom side;
- connect with Navigator Software (on a Win7 PC).

No way to resolve.
Is there a trick/procedure to save the NAS or it is definitely bricked?

Thanks for your reply
