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!

Replacing
1. Make sure all coil elements are off and cool before replacing the coil elements and reflector bowls.
2. Line up openings in the reflector bowl with the coil element receptacle and the element hold-down clip.
3. Hold the coil element as level as possible with the terminal just started into the receptacle. Push the coil element terminal into the receptacle.
4. When terminal is pushed into the receptacle as far as it will go, push down the edge of the coil element opposite the receptacle. The element hold-down clip will keep the coil element from moving around. NOTE: Reflector bowls reflect heat back to the cookware on the coil elements. They also help catch spills. When they are kept clean, they reflect heat better and look new longer. If a reflector bowl gets discolored, some of your cookware may not be flat enough, or some may be too large for the coil element. In either case, some of the heat that�s meant to go into or around the cookware goes down and heats the reflector bowl. This extra heat can discolor it. 47
