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 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 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.
Unleaded solder
Boards requiring use of unleaded solder are printed with the lead­free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.)
SAFETY CHECK-OUT
After correcting the original service problem, perform the fol­lowing safety checks before releasing the set to the customer: Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.
LEAKAGE
The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes). Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers’ instructions to use these instruments.
2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a pas­sive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)
To Exposed Metal
Par ts on Set
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40°C higher than
ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350°C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful!
• Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.
• Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

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. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS AP­PEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB­LISHED BY SONY.

SERVICING NOTE

SELF-DIAGNOSIS FUNCTION
When the self-diagnosis function is activated to prevent the player from malfunctioning, three character service numbers in a combi­nation with a message appears in the display. In this case, check the following table.
Message Explanation
C12/ You are trying to record a disc that cannot be Cannot Copy played back in DECK-A or with an external
device, such as CD-ROM or VIDEO CD.
• Remove the disc, and then insert a music CD for playback.
C13/ Recording has not been completed successfully Rec Error because of vibration.
• Relocate the unit in a place free of vibration and restart the recording again. The disc you try to record is excessively dirty (such as oilstained or finger marked) or scratched. Or the disc is not normal.
• Replace the disc with another one and restart the recording again.
C14/ The unit did not read the TOC information.
TOC Error • Insert other discs.
C41/ The sound source you are trying to record is Cannot Copy a copy of a commercial music software. Or you
are trying to record on a CD-R/CD-RW digitally.
• Because of the restriction of the Serial Copy Management System, you cannot record copies of commercial music software or MP3 files on DECK A. Neither can you digitally record from a CD-R/CD-RW.
• Use analog recording through the ANALOG IN jack when you record from other units. Or use Synchro-Recording when you record from DECK A. (The recording mode is automati cally changed to analog recording.)
C71/ If this message is displayed Din Unlock momentarily, this is not an error. It is caused
by the digital signal during recording.
During recording of a digital sound source, the connecting cable has been disconnected or the player of the sound source has turned off.
• Connect the cable or turn on the digital player.
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 repain parts. The flexible board is easily damaged and should be handled with care.
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 pick­up block. Therefore, when checking the laser diode emission, ob­serve from more than 30 cm away from the objective lens. The emission check enables continuous checking of the S curve.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK
Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveform is output three times.
