SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electro- static break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body.

During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts.

The flexible board is easily damaged and should be handled with care.

NOTES ON LASER DIODE EMISSION CHECK

Never look into the laser diode emission from right above when checking it for adjustment. It is feared that you will lose your sight.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-5R)

The laser diode in the optical pick-up block may suffer electro- static break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform mea- sures against electrostatic break-down sufficiently before the op- eration. The flexible board is easily damaged and should be handled with care. (See Fig.1)

•In performing the repair with the power supplied to the set, re- moving the MAIN board causes the set to be disabled.

In such a case, fix a convex part of the open/close detect switch (S806 on MAIN board) with a tape in advance.

Handle the FLEXIBLE board (overwrite head) with care, as it has been soldered directly to the MAIN board.

In repairing the component side of MAIN board, connect the FLEXIBLE board (overwrite head) and the MAIN board with the lead wires in advance. (See Fig.2)

•The shipment data will be cleared when the NV is reset. There- fore, change the NV adjusted values following the Change of NV Adjusted Values immediately after the NV was reset. (See page 20)

•This set requires the patch data in the nonvolatile memory (IC804) to be rewritten using the application, when the MAIN board or nonvolatile memory (IC804) was replaced. (See page 30)
