The display shows a code made up of three letters and a message alternately to show you the problem. To solve the problem refer

13、 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 a

14、s a CD-ROM. p Remove the disc and turn off the system once, then turn it on again. C13/REC Error Recording could not be performed properly. p Move 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. p Replace

15、 the MD and start recording over from the beginning. C13/Read Error The MD deck cannot read the disc information properly. p Remove 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

16、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). 1. SERVICING NOTES 4 2.

The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. Laser component in this product is capabl

21、e of emitting radiation exceeding the limit for Class 1. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the mi

22、nus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing Keep the temperature of soldering iron around 270C 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 w

23、hen 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,

24、 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

25、 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 ab

26、ove 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 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION.

27、 REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. 5 HCD-CP500MD DRAWING OUT THE TRAY DURING POWER OUT CLEANING THE OPTICAL PICK-UP (CD PLAYER) Tray Move the cam block in the direction of the arrow with a finger.
