Panasonic Telephone Answering System Looking For Owner's Manual For Panasonic KX-F3500 Telephone Answering System With Fax?

Looking for owner's manual for Panasonic KX-F3500 Telephone answering system with fax? - panasonic telephone answering system

This is an old machine. Panasonic no longer supports or manuals. Machine works perfectly. Had enough. Type of thermal paper.
Problem: I have no manual to program it. This is a KX-F3500 "Phone Fax care system.
It was, I think one of the EASA Series Phone 1990s. If anyone would like a manual, are provided with multi-national companies, or scan and send files, jpg or something else?
