Thank you for having the manual I needed for an older model Aiwa stero I had found on Ebay --- I wanted the Aiwa because I had tapes and cd's but I did not have a manual as to how to operate the system... I found what I needed and it has enabled me to set the system up for my enjoyment.
I wished detailed information of the JBL S310 and here I found it! Very happy with the service from this site!
