How to deregister

[ogs]

I have recently sold my D200 and the new owner wants me to deregister it, how do I do this? No help on Dev web site, I can see how to add a product but not delete one. Can anyone help?

I asked Devialet support about this back in February. I got this answer from them:

1: The warranty is transferable. Just delete the amplifier (serial number) from your online account, so that the new user can register it in his account.

EDIT: they may have changed this in their new web lay out. I have not checked after the change.
