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.

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)

: 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 viscou-s (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.

Design and specifications are subject to change
without notice

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

While depressing the ENTER button, press the power ?/1
button to turn on the main power.
Either the message “C.MODE.AV 1” or “C.MODE.AV 2”
appears.

SHIPMENT MODE

• All preset contents are reset to the default setting.

• Procedure:
While depressing the SPEAKERS (OFF/A/B/A+B) and the
FM buttons simultaneously, press the power ?/1 button to
turn on the main power.
“CLEARED” appears and switch off the set.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)

For Schematic Diagrams.
Note:

• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except f or electrolytics and
tantalums.

• All resistors are in Ω and 1/
specified.

• % : indicates tolerance.

• f : internal component.

• 2 : nonflammable resistor.

• 5 : fusible resistor.

• C : panel designation.
Note: The components identified by mark 0 or dotted

line with mark 0 are critical for safety.
Replace only with part number specified.

• A : B+ Line.

• B : B+ Line.

•Voltages and wavef orms are dc with respect to ground un­der no-signal (detuned) conditions.
No mark : FM

•Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.

•Waveforms are taken with a oscilloscope.

• Circled numbers refer to waveforms.

• Signal path.
