CLASS 1

LASER PRODUCT

The lightning flash with arrowhead, within an equilateral tri-

angle is intended to alert the user of the presence of

uninsulated "dangerous voltage" within the product’s

enclosure; that may be of sufficient magnitude to consti-

tute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intend-

ed to alert the user of the presence of important operating

and maintenance (servicing) instructions in the literature

accompanying the appliance.

2. Safety check out

(Only U.S.A. model)
Before returning the product to the customer, make leakage current or resistance measurements
to determine that exposed parts are acceptably insulated from the supply circuit.

Parts marked with the symbol are critical with regard to the risk of fire and electric shock.
Replace only with parts recommended by the manufacturer.

TESTING PROCEDURE

(1) Load the test disc (Sony Test CD YEDS-7) and set the unit into PLAY mode.
(2) Connect the scope to R132 (Pin 41 of U101) and DGND (J334).

Scope setting: Coupling : AC.

Vertical sensitivity : 0.2 V/ div.
Horizontal time base : 0.5 µS/div.

(3) Observe the waveform is 2.0V p-p +/-5% and the eye pattern is at its best shape (see FIG. 1).

FIG. 1 (a) FIG. 1 (b) Poor eye pattern

FIG. 1 (C) Good eye pattern

IMPORTANT NOTES

INSTRUCTION FOR HANDLING OPTICAL SYSTEM BLOCK PICK-UP

Electrostatic breakdown of the laser diode in the optical system block may occur due to a poten­tial difference caused by electrostatic charge accumulated on clothing, human body, etc. A ground
must be provided as follows to prevent any electrostatic charge during unpacking or repair work.

1. Ground for Human Body
Be sure to wear a ground band (1M ohm) that is properly to remove any static electricity that may

be charged on the body.

2. Ground for Work Bench
Be sure to place a conductive sheet (1M ohm) or copper plate with proper grounding on the work

bench or other surface on which the pick-up is to be placed.

3. Because the static electricity charge on the clothing does not discharge through the body
grounding band, do not let clothing to get in contact with the pick-up unit.

PRECAUTIONS FOR CHECKING BEAM EMISSION

The laser beam of this unit is focused on the reflecting surface of the objective lens in the optical
system block. Therefore, keep your eyes at least 12 inches (30 cm) away from the objective lens
when the laser diode is ON.
(Operation Check Method for Laser Diode and Focus Search Function.)
When the POWER switch is turned ON after the chucking plate is removed, observe the objective
lens and confirm that the following operations are performed properly.
(The optical system should be at the lead-in area position when it is checked at this time.)
(1) The laser should be at the innermost position after the chucking plate is removed.
(2) The diffused light of the laser beam can be seen when the POWER switch is turned ON.
(3) Vertical (up and down) movement of the ojective lens (2 or 3 times) will take place.

INCORRECT CORRECT

NOTE: Laser diodes are so susceptible to damage from

static electricity that even if a static discharge does not
ruin the diode, it can shorten its life or cause it to work
improperly.

PRECAUTIONS WHEN CHANGING LASER PICK-UP

When removing the pick-up assembly, short circuit the PCB tracks on the optical block as show in
the drawing in order to protect the pick-up before removal.

NOTE: Replacement pick-up assemblies are supplied with the PCB pattern already protected.
DO NOT REMOVE THE SHORT CIRCUITS UNTIL YOU HAVE FINISHED FITTING THE PICK-

UP.

Caution:

Laser diodes are extremely susceptible to damage from static electricity. Even if a static dis­charge does not ruin the diode, it can shorten its life or cause it to work improperly. When replac­ing the pick-up, use a conductive mat, a grounded soldering iron, and so on, to protect the laser
diode from static damage.
