This remove was a replacement for older model of remote RC027SR as that remote was discontinued, this was for Marantz processor AV8802A, the remote worked well with all features working on key pad, the only difference between the remote is HEOS button on new remote and on older remote, was on-line music button, but the button operated the old operation on processor. very happy as finally found a replacement for older remote, very happy with service from company.
