SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE
WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE
PA RTS 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.

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 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.
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.

TEST MODE
FACTORY PRESET MODE
* All preset contents are reset to the default setting.
* Procedure:
While depressing the PLII and the PRESET TUNING + buttons simultaneously, press the power
button to turn on the
?/1
main power. The message “FACTORY” appears and the present
contents are reset to the default values.
RDS AUTOBETICAL MODE
* This mode is installed in the Europe models only. When this
mode is used, the receiver scans the broadcasts that can be received by the tuner, and sets up the broadcasts. Be sure to start
scanning after connecting the antenna.
* Procedure :
1. Check that the antenna is connected.
2. While depressing the INPUT SELECTOR button, press the
?/1 button to turn on the main power.
3. The message “AUTO-BETICAL SELECT” appears and the
receiver starts scanning.
MICRO/NORMAL SPEAKER SELECTION MODE
* Either the micro speaker mode or normal speaker mode can be
selected.
*Procedure
While depressing the MUTING button, press the power
?/1
button to turn on the main power. Either the message “MICRO
SP.” or “NORM. SP.” appears. Select the desired mode.
SOUND FIELD CLEAR MODE
* The preset sound field is cleared when this mode is activated.
Use this mode before returning the product to clients upon
completion of repair.
* Procedure:
While depressing the SOUND FIELD button, press the power
button to turn on the main power. The message
?/1
“SF. CLR” appears and initialization is performed.
ALL CLEAR MODE
* The all preset value is cleared when this mode is activated.
* Procedure :
While depressing the PLII and the PRESET TUNING - buttons
simultaneously, press the power
button to turn on the main
?/1
power. The message “CLEARED” appears and clear all preset
value.
SOFTWARE VERSION DISPLAY MODE
* The software version is displayed.
* Procedure:
While depressing the SOUND FIELD and the PRESET TUNING - buttons simultaneously, press the power
?/1
button to
turn on the main power. The model name, destination and the
software version are displayed.
KEY CHECK MODE
* Button check
* Procedure:
While depressing the MUTING and the INPUT SELECTOR
buttons simultaneously, press the power
the main power.
“REST 06” appears.
Every pressing of any button other than ?/1 counts down the
buttons. The buttons which are already counted once are not
counted again. When all buttons are pressed “REST 00” appears.

FLUORESCENT INDICATOR TUBE TEST MODE
* All fluorescent segments are tested. When this test is activated,
all segments turn on at the same time, then each segment turns
on one after another.
* Procedure:
While depressing the MUTING and the PRESET TUNING
- buttons simultaneously, press the power
button to turn
?/1
on the main power.
1. All segments turn on.

TUNER CHECK MODE
*Tuner check
* Procedure :
While depressing the SOUND FIELD and the INPUT SELECTOR buttons simultaneously, press the power ?/1 but-
ton to turn on the main power. “TUN CHK” appears and the
tuner checking is performed.
DSP TEST MODE
* DSP tests are performed.
* Procedure :
There are two different methods to enter the test mode.
(1) While depressing the INPUT SELECTOR and PRESET
TUNING - buttons simultaneously, press the power ?/1
button to turn on the main power.
(2) When the set is turned on, by using the remote controller, press
the ENTER button three times, then press the MAIN MENU
button one time and thenpress the MUTING button one time.
