TABLE OF CONTENTS
SAFETY CHECK-OUT
(US model only)
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 microampers).
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)

1. When the front panel is removed, the VR board is removed at the
same time. Consequently the LEDs cannot be turned on and the
sound volume cannot be increased or decreased from the remote
control.
2. When servicing the DIGIT AL board, be sure to connect the earth
land of the DIGITAL board with the chassis frame so that the
earth potential of the DIGITAL board must not be floated from
the chassis frame.

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 ENTER, the LEVEL and the EQ buttons
simultaneously, press the power [1/u] button to turn on the main
power. All segments turn on at the same time, then each segment
90
turns on press the ENTER button.
FACTORY SET MODE
* All preset contents are reset to the default setting.
* Procedure:
While depressing the SET UP, the LEVEL and the ENTER buttons
simultaneously, press the power [1/u] button to turn on the main
power. The message Factry Set appears and the present contents
are reset to the default values.
ALL CLEAR MODE
* All preset contents are cleared when this mode is activated. Use
this mode before returning the product to clients upon completion
of repair.
* Procedure:
While depressing the SET UP button simultaneously, press the
power [1/u] button to turn on the main power. The machine enters
the DEMO mode.DEMO mode: Wait a while, then the
demonstration starts. If the power [1/u] button is pressed often
the demonstration has started, the power is turned off, and the
demonstration resumes if the power [1/u] button is pressed again.
ALL CLEAR mode; If the power [1/u] button is pressed often
the machine enters the DEMO mode, but before the demonstration
starts, the display is turned off. Press [1/u] again. No response is
returned. The press [1/u] again. The preset data is cleared and
the machine enters the normal power-on state.
TEST MODE
AM CHANNEL STEP 9 kHz/10 kHz
SELECTION MODE (US,Canadian Model)
* Either the 9 kHz step or 10 kHz step can be selected for the AM
channel step.
* Procedure:
Set the FUNCTION to AM. Turn off the main power.
While depressing the TUNING+ button or the PRESET TUNING
+ button, press the power [1/u] button to turn on the main power.
Either the message AM 9kHz Step or AM 10kHz Step appears.
Select the desired step.
DSP TEST MODE
* It tests whether the DSP works correctly or not. When the DSP
test is activated, the test data is output from the DSP (IC1401:
CXD2712R) of the DIGITAL board and is written in the RAM
(IC1402: IDT71V016S). When the test data is read from the RAM
by the DSP, the data output must be equivalent to the original
data. If they disagree, an error is triggered. Errors can be caused
by the broken data line or defective soldering.
* Procedure
While pressing the SETUP, LEVEL and SUR buttons, press the
POWER button to enter the DSP test mode. The message DSP
TEST MODE appears. When an error occurs, the message DSP2
ERROR is displayed. When there is no error, the message DSP2
NO ERROR appears and the 1 kHz signal is output to all channels.
Then, the mode can be switched the (SIGN W AVE) (THROUGH)
and (INPULSE) mode.
VERSION MODE
* When this mode is used, the microprocessor version number is
displayed.
* Procedure:
Press the POWER button while pressing the ENTER, LEVEL,
and SUR buttons to turn on the power. The microprocessor version
number appears as follows.
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 MODE button, press the
power [1/u] button to turn on the main power. The message S.F
Initialize appears and initialization is performed.

THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this necessary note is printed in each
block.)
For schematic diagrams.
Note:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and 1/
specified.
• % : indicates tolerance.
• 2 : nonflammable resistor.
• 1 : fusible resistor.
• C : panel designation.
Note:
The components identified by
mark ! or dotted line with mark
! are critical for safety.
Replace only with part number
specified.
• U : B+ Line.
• V : B– Line.
• H : adjustment for repair.
• Voltages and waveforms 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.
F : FM
J : CD
c : DIGITAL
I : PHONO

Note:
Les composants identifiés par
une marque ! sont critiques
pour la sécurité.
Ne les remplacer que par une
pièce portant le numéro spécifié.
For printed wiring boards.
Note:
• X : parts extracted from the component side.
• ® : Through hole.
• b : Pattern from the side which enables seeing.
