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.

NAD - C 542 PCB TESTING POINTS DIAGRAM

TESTING PROCEDURE
(1) Load the test disc (Sony Test CD YEDS-7) and set the unit into PLAY mode.
(2) Connect the scope to R227 (Pin 15 of U101) and DGND (J144).

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 sur-

face 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 objective 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.
