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!

3. Hokf the surface unit as level as possible with the terminal just started into the receptacle. Push the surface unit terminal into the receptacle.
4. When terminal is pushed into the receptade as far as it will go, push down the edge of the surface unit opposite the receptacle. The element hokfdown clip will keep the surface unit from moving around. NOTE: Reflector bowls reflect heat back to the utensils on the surface units. They also help catch spills. When they are kept clean, they reflect heat better and look new longer. lf a reflector bowl gets discolored, some of the utensils may not be flat enough, or some may be too large for the surface unit. In either case, some of the heat that�s meant to go into or around a utensil goes down and heats the reflector bowl. This extra heat can discolor it.
