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!

Changing the Light Bulb
If a lamp fails to function check that the bulb is screwed into the holder. If bulb failure has occurred then it should be replaced with a 220-240V 40W clear cylindrical shape bulb with a small E14 screw thread. Charcoal filters, grease filters and light bulbs can be obtained from your local Service Force Centre This appliance can be a fire hazard if the grease and charcoal filters are not cleaned and replaced as recommended.
