IMPORTANT NOTICE

This manual has been provided for the use of authorized YAMAHA Retailers and their service personnel.

It has been assumed that basic service procedures inherant to the industry, and more specifically YAMAHA Products, are already

known and understood by the users, and have therefore not been restated.

WARNING: Failure to follow appropriate service and safety procedures when servicing this product may result in personal

injury, destruction of expensive components and failure of the product to perform as specified. For these reasons,

we advise all YAMAHA product owners that all service required should be performed by an authorized

YAMAHA Retailer or the appointed service representative.

IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or

recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form.

The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and

service departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable

and specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please contact

the distributor's Service Division.

WARNING: Static discharges can destroy expensive components. Discharge any static electricity your body may have accumu-

lated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss).

IMPORTANT: Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the unit.

COMPACT DISC PLAYER

SERVICE MANUAL

CDX-596

TO SERVICE PERSONNEL

1. Critical Components Information.

Components having special characteristics are marked

and must be replaced with parts having specifications equal

to those originally installed.

Meter impedance should be equivalent to 1500 ohm shunted

by 0.15µF.

Leakage current must not exceed 0.5mA.

Be sure to test for leakage with the AC plug in both

polarities.

CAUTION: USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE

SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

THE COMPACT DISC PLAYER SHOULD NOT BE ADJUSTED OR REPAIRED BY ANYONE EXCEPT PROPERLY

QUALIFIED SERVICE PERSONNEL.

PROTECTION OF EYES FROM LASER BEAM DURING SERVICING

This set employs a laser. Therefore, be sure to carefully

follow the instructions below when servicing .

1. Laser Diode Properties

2. When checking the laser diode emission, keep your

eyes more than 30 cm away from the objective lens.

Material

: GaAlAs

Wavelength

: 780 nm

Emission Duration : Continuous

Laser Output

: max. 44.6 µW*

* This output is the value measured at a distance of

about 200 mm from the objective lens surface on

the Optical Pick-up Block.

WARNING: CHEMICAL CONTENT NOTICE!

The solder used in the production of this product contains LEAD. In addition, other electrical/electronic

and/or plastic (where applicable) components may also contain traces of chemicals found by the

California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects

or other reproductive harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH

FOR ANY REASON WHATSOEVER!

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale

solder fumes or expose eyes to solder/flux vapor!

If you come in contact with solder or components located inside the enclosure of this product, wash your

hands before handling food.

CAUTION: USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE

SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
