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!

The Hinged Grill
Some models are fitted with a hinged grill element, to enable you to clean the roof of the oven easily. Before proceeding ensure the oven is cool and is isolated from the electricity supply. Undo the screws which hold the grill in place (see Fig. 21). When doing this operation for the first time, we recommend using a screwdriver. Then gently pull the grill downward to allow access to the oven roof. Clean the oven roof with a suitable cleaner and wipe dry before replacing the hinged grill element. Gently push up the grill element into place and firmly screw into place the holding nuts. Ensure the grill holding nuts are firmly in place to avoid the grill falling down when in use. Fig. 21
When cooking meat, the grease filter must be fitted over the oven fan by clipping it over the vents in the back panel. This will prevent a built-up of fat on the fan impellor. Do not use abrasive materials to clean the seal. The grease filter is dishwasher proof. When cooking is completed and the oven has cooled down, remove the filter by pushing the protruding tongue on the filter upward (see Fig. 22). Wash the filter after use using warm soapy water. Fit the grease filter only when roasting.
