Self-diagnosis display

This system has a Self-diagnosis display

function to let you know if there is a system

malfunction. The display shows a code made

up of three letters and a message alternately to

show you the problem. To solve the problem

refer to the following list. If any problem

persists, consult your nearest Sony dealer.

C11/Protected

The MD is protected against erasure.

Remove the MD and slide the tab to close the

slot (see page 16).

C12/Cannot Copy

You tried to record a CD or MD with a format that

the system does not support, such as a CD-ROM.

pRemove the disc and turn off the system once,

then turn it on again.

C13/REC Error

Recording could not be performed properly.

pMove the system to a stable place, and start

recording over from the beginning.

The MD is dirty or scratched, or the MD does not

meet the standards.

pReplace the MD and start recording over from

the beginning.

C13/Read Error

The MD deck cannot read the disc information

properly.

pRemove the MD once, then load it again.

C14/Toc Error

The MD deck cannot read the disc information

properly.

pReplace the MD.

pErase all the recorded contents of the MD using

All Erase Function (see page 27).

C41/Cannot Copy

The sound source is a copy of commercially

available music software.

pThe Serial Copy Management System prevents

making a digital copy (see page 47).

HCD-J300 SECTION 1

SERVICING NOTE

This appliance is classified as a CLASS 1 LASER product. The

CLASS 1 LASER PRODUCT MARKING is located on the rear

exterior.

Laser component in this product is capable

of emitting radiation exceeding the limit for

Class 1.

CAUTION

Use of controls or adjustments or performance of procedures

otherthanthose specifiedherein may resultin hazardousradiation

exposure.

Notes on chip component replacement

•Never reuse a disconnected chip component.

•Notice that the minus side of a tantalum capacitor may be

damaged by heat.

Flexible Circuit Board Repairing

•Keep the temperature of soldering iron around 270˚C

during repairing.

•Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).

•Be careful not to apply force on the conductor when soldering

or unsoldering.

NOTES ON HANDLING THE OPTICAL PICK-UP

BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostatic

break-down because of the potential difference generated by the

charged electrostatic load, etc. on clothing and the human body.

During repair, pay attention to electrostatic break-down and also

use the procedure in the printed matter which is included in the

repair parts.

The flexible board is easily damaged and should be handled with

care.

FOR CD

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on

the disc reflective surface by the objective lens in the optical pick-

up block. Therefore, when checking the laser diode emission,

observe from more than 30 cm away from the objective lens.

FOR MD

NOTES ON LASER DIODE EMISSION CHECK

Never look into the laser diode emission from right above when

checking it for adjustment. It is feared that you will lose your sight.

This caution

label is

located inside

the unit.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0OR DOTTED LINEWITH

MARK 0ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS

LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE

COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS

APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS

PUBLISHED BY SONY.
