CAUTION ON REPLACEMENT OF OPTICAL

The laser diode in the optical pickup block is so

sensitive to static électricity surge current and etc,

that the components are liable to be broken down

or its reliability remarkably deteriorated.

PRECAUTIONS

1.Ground for the work-desk.

Place a conductive sheet such as a sheet of copper

(with inpedance lower than 10M) on the work-

desk and place the set on the conductive sheet so

that the chassis.

2.Grounding for the test equipment and tools.

Test equipments and toolings should be grounded

in order that their ground level is the same the

ground of the power source.

PICKUP

During repair,carefulley take the following precautions.

(The following precautions are included in the service

parts.) |

3.Grounding for the human body.

Be sure to put on a wrist-strap for grounding whose

other end is grounded.

Be particularly careful when the workers wear

synthetic fiber clothes, or air is dry.

4.Select a soldering iron that permits no leakage and

have the tip of the iron well-grounded.

5.Do not check the laser diode terminals with the

probe of a circuit tester or oscilloscope.

CR-185

PROTECTION OF EYES FROM LASER BEAM DURING SERVICING This set employs a laser. Therefore, be sure to follow

carefully the instructions below when servicing.

WARNING!!

WHEN SERVICING, DO NOT APPROACH THE LASER

EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS

NECESSARY TO CONFIRM LASER BEAM EMMISION,

BE SURE TO OBSERVE FROM A DISTANCE OF MORE

THAN 30cm FROM THE SURFACE OF THE OBJECTIVE

LENS ON THE OPTICAL PICK-UP BLOCK.

LASER WARNING LABELS The label shown below are affixed.

ADJUSTMENT PROCEDURES It is not necessary to perform the adjustment of optical pickup.

This confirmation should be made when replacing the opucal pickup.

1). Connect the oscilloscope to test points RF and VC.

2). Turn the power switch on.

3). Load the test disc YEDS-18 on the tray and press the play button.

4). Confirm that the waveform on the oscilloscope is opumum eye —

pattern and optimum level as shown photo 1.

Optimum eye pattern means that shape "©" can be clearly

distinguished at the center of the waveform.

REFERENCE

Focus/Tracking Gain Adjustment

A frequency response analyzer is necessary in

order to perform this adjustment exactly.

However, this gain has a margin, so even if it 1s

slightly off, there is no problem. Therefore, do not

perform this adjustment.

_Focus/tracking gain determines the pick-up follow-

up (vertical and horizontal) relative to mechanical

noise and mechanical shock when the 2-axis device

Operate.

However, as these reciprocate, the adjustment is at

the point where both are satisfied.

@ When gain is raised, the noise when the 2-axis

device operates increases.

@ When gain is lowered, it is more susceptible to

mechanical shock and skipping occurs more easily.

@ When gain adjustment is off, the symptoms below

appear.

Note: Since exact adjustment cannot be performed, remem-

ber the positions of the controls before performing the

adjustment. If the positions after the simple adjust-
