ATTENTION AU COMPOSANT AYANT RAPPORT
Ã- LA SÉCURITÉ!
LES COMPOSANTS IDENTIFIÉS PAR UNE MARQUE 0
SUR LES DIAGRAMMES SCHÉMATIQUES ET LA LISTE
DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ
DE FONCTIONNEMENT. NE REMPLACER CES COM-
POSANTS QUE PAR DES PIÈCES SONY DONT LES
NUMÉROS SONT DONNÉS DANS CE MANUEL OU

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 PUB-
LISHED BY SONY.
Notes on chip component replacement
-N ever reuse a disconnected chip component.
- Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
-K eep the temperature of the soldering iron around 270 ËšC dur-
ing 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.
SAFETY CHECK-OUT
After correcting the original service problem, perform the follow-
ing safety check 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 TEST
T he AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
r eturn 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 indica-
tion is 0.75 V, so analog meters must have an accurate low-
v oltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-
amples of a passive VOM that is suitable. Nearly all battery
operated digital multimeters that have a 2 V AC range are suit-
able. (See Fig. A)

Use of controls or adjustments or performance of procedures

About CD-Rs/CD-RWsThis player can play CD-Rs/CD-RWs
recorded in the CD-DA format*, but
playback capability may vary depending on
the quality of the disc and the condition of
the recording device.
*
CD-DA is the abbreviation for Compact
Disc Digital Audio. It is a recording
standard used for Audio CDs.
On power sources-F or AC operation,
use the supplied
AC power
adaptor; do not
use any other type.
- The player is not disconnected from the
AC power source (mains) as long as it is
connected to the wall outlet, even if the
player itself has been turned off.
- Unplug the player from the wall outlet
when it is not to be used for an extended
period of time.
-F or battery operation, use six size D (R20)
batteries.
- When the batteries are not to be used,
remove them to avoid damage that can be
caused by battery leakage or corrosion.
- The nameplate indicating operating
voltage, etc. is located at the bottom.

UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free 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)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
- Unleaded solder melts at a temperature about 40 ËšC 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 ËšC.
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 viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges oc-
cur 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.
