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!

Precautions
1-4 Handling the optical pick-up
The laser diode in the optical pick up may suffer electrostatic breakdown because of potential static electricity from clothing and your body. The following method is recommended. (1) Place a conductive sheet on the work bench (The black sheet used for wrapping repair parts.) (2) Place the set on the conductive sheet so that the chassis is grounded to the sheet. (3) Place your hands on the conductive sheet(This gives them the same ground as the sheet.) (4) Remove the optical pick up block (5) Perform work on top of the conductive sheet. Be careful not to let your clothes or any other static sources to touch the unit. �Be sure to put on a wrist strap grounded to the sheet. �Be sure to lay a conductive sheet made of copper etc. Which is grounded to the table.
