Why can't I select EX/ES mode on my Marantz SR5003?

If you cannot select EX/ES mode on your Marantz Receiver, it may be because "Surround center= NONE" has been selected in SPEAKERS SIZE SETUP. Make the correct setting. Alternatively, the input signal may be incompatible, so use a 5.1channel source.
