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!

Storage Shelves/Storage Racks
Depending on the model, your appliance is equipped with either glass storage shelves or storage racks. A glass storage shelf must always remain inserted into the lower guide track above the fruit and vegetable trays, so that fruits and vegetable remain fresh longer. The remaining storage shelves can be adjusted to various heights: Pull the storage shelf forward and remove. Insert at a different height.
