the customer.
(1) Be sure that no built-in protective devices are
defective or have been defeated during servicing.
(1)Protective shields are provided to protect both
the technician and the customer. Correctly replace
all missing protective shields, including any
removed for servicing convenience.
(2)When reinstalling the chassis and/or other
assembly in the cabinet, be sure to put back in place
all protective devices, including, but not limited to,
nonmetallic control knobs, insulating fish papers,
adjustment and compartment covers/shields, and
isolation resistor/capacitor networks. Do not operate
this instrument or permit it to be operated without
all protective devices correctly installed and
functioning.

Such components commonly are called Electrostatically (8) Minimize body motions when handling

(1) Immediately before handling any semiconductor
component or semiconductor-equipped assembly,
drain off any electrostatic charge on your body by
touching a known earth ground. Alternatively,
obtain and wear a commercially available
discharging wrist strap device, which should be
removed for potential shock reasons prior to
applying power to the unit under test.

(2) After removing an electrical assembly equipped
with ESD devices, place the assembly on a
conductive surface such as aluminum foil, to
prevent electrostatic
charge buildup or exposure of the assembly.

(3) Use only a grounded-tip soldering iron to solder or
unsolder ESD devices.

(4) Use only an anti-static solder removal devices.
Some solder removal devices not classified as
"anti-static" can generate electrical charges suffi-
cient to damage ESD devices.

(5) Do not use freon-propelled chemicals. These can
generate electrical charges sufficient to damage
ESD devices.

(6) Do not remove a replacement ESD device from its
protective package until immediately before
installing it. (Most replacement ESD
devices are packaged with leads electrically shorted
together by conductive foam, aluminum foil or
comparable conductive materials).

(7) Immediately before removing the protective
materials from the leads of a replacement ESD
device, touch the protective material to the
chassis or circuit assembly into which the device
will be installed.

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 cloth-
ing 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 Fig.1-3
chassis is grounded to the sheet.
(6) Short the short terminal on the PCB, which is inside
(3) Place your hands on the conductive sheet(This the Pick-Up ASS'Y, before replacing the Pick-
gives them the same ground as the sheet.) Up. (The short terminal is shorted when the Pick-
Up Ass'y is being lifted or moved.)
(4) Remove the optical pick up block
(7) After replacing the Pick-up, open the short terminal
(5) Perform work on top of the conductive sheet. Be on the PCB.
careful to let your clothes or any other static
sources touch the unit.

u Be sure to put on a wrist strap grounded to the
sheet.
u Be sure to lay a conductive sheet, that is
grounded to the table, made of copper.
