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.

(6) Short the short terminal on the PCB, which is inside the Pick-
Up ASS’Y, before replacing the Pick-Up. (The short terminal is
shorted when the Pick-Up Ass’y is being lifted or moved.)
(7) After replacing the Pick-up, open the short terminal on the PCB.
