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!

Cleaning the hinged grill
This model has been fitted with a hinged top grill element to enable you to clean the roof of the oven easily. Before proceeding ensure the oven is isolated from the electricity supply. Then undo the screw which holds the grill in place. (see Fig. 9) Then gently pull the grill downward to allow access to the oven roof. (see Fig. 10)

Gently push up the grill element into place and firmly screw into place the holding nut. NOTE: Ensure the grill holding nut is firmly in place to avoid the grill falling down during operation.
