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!

Installation I Screwing the Faceplate on the Unit
If you want to fasten the faceplate to the main unit so that it does not fall off, screw in the provided screw (Ã¸4 Ã 16 mm) in the hole shown below.
Never insert the taptite screw (Ã¸4 Ã 16 mm) in any other screw hole than the one specified. If you screw it in another hole, it will contact and may cause damage to the mechanical parts inside the unit.
