IMPORTANT SERVICE NOTES (FOR U.S.A. ONLY)
BEFORE RETURNING THE AUDIO PRODUCT
(Fire & Shock Hazard)
Before returning the audio product to the user, perform the
following safety checks.
1. Inspect all lead dress to make certain that leads are not
pinchedorthathardwareisnotlodgedbetweenthechassis
and other metal parts in the audio product.
2. Inspect all protective devices such as insulating materials,
cabinet,terminalboard,adjustmentandcompartmentcovers
or shields, mechanical insulators etc.
3. To be sure that no shock hazard exists, check for leakage
current in the following manner.
* Plug the AC line cord directly into a 120 volt AC outlet.
* Using two clip leads, connect a 1.5 kohm, 10 watt resistor
paralleled by a 0.15 µF capacitor in series with all exposed
metal cabinet parts and a known earth ground, such as
conduit or electrical ground connected to earth ground.
* Use a VTVM or VOM with 1000 ohm per volt, or higher,
sensitivity to measure the AC voltage drop across the
resistor (See diagram).
* Connect the resistor connection to all exposed metal parts
havingareturnpathtothechassis(antenna,metalcabinet,
screw heads, knobs and control shafts, escutcheon, etc.)
and measure the AC voltage drop across the resistor.

3. Tuner Test Mode (TEST 2)
1. Outline of tuner (radio) test mode
The tuner test mode is intended to store the adjustment
and measurement frequencies in the preset memory
CH. Whenadjustingthetuner section in the production
line,adjustingpersonnelarenotrequiredtosetfrequency.
2. Details of tuner test mode
Press the "TUNER(BAND)" and "VOLUME UP" buttons
in POWER OFF state and turn on the power by the use
of "POWER ON/STAND BY" button to preset and store
frequencyforadjustmentandmeasurementofdestination
specified by the AREA terminal in the preset memory
CH. However, Ordinary 1 and Ordinary 2 are stored in
the destinations when the test mode is obtained.
(As for frequencies to be preset and stored for each
destination, refer to item 3.)
The tuner test mode is started from preset No.1.
The operations of test mode are identical with the ordinary
operations of TUNER function. FUNCTION switching is
invalid.
It is necessary to discard the content of preset memory
when the tuner test mode is ended; be sure to write "0000"
or "1111" bits in the memory to be checked for judging
memory error at initial setting and to initialize memory.
Whenthetuner test mode isobtained,the following display
lights for one second.
•TheTUNERTEST02modeisobtainedwith >>+MEMORY/
SET+POWERON/STAND-BY.->TurnoffACintheTEST02
mode to restore the initial state.
Turn off POWER to protect the memory of TEST02 mode.
Turn off POWER again to obtain the ordinary operation
while the data is stored in the memory (besides TUNER).
IfACOFF state is maintainedinthis state for about1/2day,
start is executed in the initial state.
• To clear the whole memory, insert the AC cord, pressing
MEMORY/SET + CD PLAY.

The button operations in the test mode are the same as
those of ordinary operation except volume UP/DOWN.
(1) The display is the same as that of ordinary operation
except test mode setting.
(2) Unlike the ordinary state, the volume is controlled with
the volume UP/DOWN button in accordance with the
following three steps.
Volume- ∞(STEP 0) <-> Volume-14 dB (STEP 23) <-
> Volume-0 (STEP 30)

The fade-in (when playback is started) is executed at a rate
of one step for 1 sec. After completion of fade-in, the fade-
out is executed at a rate of one step for 1 sec (WAIT 1 sec
inserted).
After completion of fade-out, the power is turned off (after
WAIT 1 sec), and the mode is shifted to the standby.
The display during operation is the same as that of ordinary
timer operation.

7. Button input diagnosis Test Mode (TEST 6)
Whenthetest mode is obtained,thefollowing is displayed.
(STAND-BY AND DEMO OFF STATUS)
This test mode is intended to check whether all the main
unit buttons can be detected. Accordingly, in this test
mode,itischeckedwhetherthe"POWERON/STANDBY"
buttonwaspressed after all thebuttonsshownbelowwere
pressed. If the result is OK, OK is displayed. If any one of
keys was not pressed, an error is displayed. In both cases
of OK termination or error termination, the mode is shifted
tothestandbymodeifthe"POWERON/STANDBY"button
is pressed subsequently.
Allmodels usingthistype ofmicrocomputerare notalways
providedwiththesamebuttons. Sincethebuttonsusedare
differentdepending onmodels,types ofbuttonsto beused
aredeterminedbywhetherSURROUND,andanelectriclid

The order of buttons to be pressed is not determined.
Accordingly, it is checked whether all buttons have been
pressed.
1. PU-IN buttons: REW/PRESET DOWN + CD STOP
Since this model is provided with SURROUND (HAVE
OR NOT), and electric CD lid, the following 10 buttons
are detected as all buttons.
PLAY, X-BASS/DEMO, FUNCTION, VOLUME UP/
DOWN, MEMORY/SET, REW, FF, STOP, CD-OPEN/

•The indicated voltage in each section is the one measured
by Digital Multimeter between such a section and the chas-
sis with no signal given.
1. In the tuner section,
indicates AM
indicates FM stereo
2. In the main section, a tape is being played back.
3. In the deck section, a tape is being played back.
4. In the power section, a tape is being played back.
5. In the CD section, the CD is stopped.
•Parts marked with “ 1” ( ) are important for
maintaining the safety of the set. Be sure to replace these
parts with specified ones for maintaining the safety and
performance of the set.
NOTES ON SCHEMATIC DIAGRAM
•Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.
•Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means pico-farad and the unit of the capacitor
without such a symbol is microfarad. As to electrolytic
capacitor, the expression “capacitance/withstand voltage”
is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
•Schematic diagram and Wiring Side of P.W.Board for this
model are subject to change for improvement without prior
notice.
