How Do I Set Stations On My Sony Digital Audio Str-k790
I purchased this audio receiver used from a garage sale and no longer have the remote. I set up a universal remote to change the volume and speaker settings. I am having difficulties finding more than 3 or 4 stations. How can I change stations manually? Is the original remote still for sale online? Thanks for your help.
