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!

� When the hood is used in its extractor function, the following rules must be followed to obtain optimal operation: - short and straight outlet ducting - keep bends in outlet ducting to a minimum - never install the ducts with an acute angle, they must always follow a gentle curve. - keep the duct as large as possible (preferably the same diameter as the outlet hole). � Failure to observe these basic instructions will drastically reduce the performance and increase the noise levels of the extractor hood.
