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!

To Operate
Select the required fan speed and light if required.
Recirculation
In the recirculation mode the contaminated air enters the cooker hood through the grease �lters. The air is cleaned by passing through the charcoal �lters before being passed back into the kitchen through the grilles in either side of the chimney stack.
