CHAPTER 1. GENERAL DESCRIPTION
[1] 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 pinched or
that hardware is not lodged between the chassis and other metal
parts in the audio product.
2. Inspect all protective devices such as insulating materials, cabinet,
terminal board, adjustment and compartment covers 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 1.5k ohm, 10 watt resistor paral-
leled by a 0.15µF 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 having a
return path to the chassis (antenna, metal cabinet, screw heads,
knobs and control shafts, escutcheon, etc.) and measure the AC
voltage drop across the resistor.
All check must be repeated with the AC line cord plug connection
reversed.
Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp. AC.) or
more is excessive and indicates a potential shock hazard which must
be corrected before returning the audio product to the owner.
FOR A COMPLETE DESCRIPTION OF THE OPERATION OF THIS UNIT, PLEASE REFER

Since this DVD/CD system incorporates the following automatic
adjustment functions, readjustment is not needed when replacing
the pickup. Therefore, different PWBs and pickups can be com-
bined freely.
Each time a disc is changed, these adjustments are performed
automatically. Therefore, playback of each disc can be performed
under optimum conditions.

[2] TEST MODE
The test mode applied to this microcomputer has three modes, namely
the ordinary test mode for adjustment or measurement, the aging test
mode, and the self-diagnosis test mode for self-judgment in case of
final product inspection.
1. Turning on the test mode
For obtaining each test mode, press the Power ON/STAND BY button,
while keeping pressing the following two buttons in the ordinary stand-
by mode (power off). In this case, the main unit buttons are valid.
When turning the POWER on with remote control buttons, test modes
are not obtained.
[Ordinary test mode]
[Self-diagnosis Test Mode]
Processes are different depending on destinations at initial settings.
2. Tuner Test Mode (TEST 2)
1. Outline of tuner (radio) test mode
The tuner test mode is intended to store the adjustment and mea-
surement frequencies in the preset memory CH. When adjusting
the tuner section in the production line, adjusting personnel are not
required to set frequency.
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 frequency for adjustment
and measurement of destination 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 mem-
ory to be checked for judging memory error at initial setting and to ini-
tialize memory.
When the tuner test mode is obtained, the following display lights for
one second.
• The TUNER TEST 2 mode is obtained with >> + MEMORY/SET +
POWER ON/STAND-BY. ->Turn off AC in the TEST 2 mode to
restore the initial state.
Turn off POWER to protect the memory of TEST 2 mode.
Turn off POWER again to obtain the ordinary operation while the
data is stored in the memory (besides TUNER).
If AC OFF state is maintained in this state for about 1/2 day, start is
executed in the initial state.
• To clear the whole memory, insert the AC cord, pressing MEM-
ORY/SET + PLAY.
3. Preset frequencies for various destinations
(random preset memory)
• The slant line sections of the table store no memory.
3. Electronic volume Test Mode (TEST 3)
When this test mode is obtained, the following display lights for one
second.
In this mode, volume is Volume -14 dB (STEP 23), FLAT AND X-BASS
ON, and start-up function to DVD/CD, respectively. The button opera-
tions 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)
3) X-BASS is switched when button is pressed.

4. Timer test Mode (TEST 4)
When this test mode is obtained, the following display lights for one
second.
Set the current time and timer time according to the following proce-
dure to reproduce the timer.
1. Set the current time to 1:00, the timer to ON time 1:05, the function
to DVD/CD, and volume to STEP 12, respectively. One minute is
counted as one second, and the timer is reproduced. 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.
5. FL Test Mode (TEST 5)
When the FL test mode is obtained, all the FL segments are lighted.
Then pressing the "PLAY" button switches display as below.
6. Button input diagnosis Test Mode (TEST 6)
When the test mode is obtained, the following 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, it is checked whether
the "POWER ON/STAND BY" button was pressed after all the buttons
shown below were 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 to the standby
mode if the "POWER ON/STAND BY" button is pressed subsequently.
All models using this type of microcomputer are not always provided
with the same buttons. Since the buttons used are different depending
on models, types of buttons to be used are determined by whether
SURROUND, and an electric lid are available at the initial setting by
MODEL port.
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 + STOP
Since this model is provided with SURROUND (HAVE OR NOT),
and electric DVD/CD lid, the following 10 buttons are detected as
all buttons.
PLAY, X-BASS/DEMO, FUNCTION, VOLUME UP/DOWN, MEM-
ORY/SET, REW, FF, STOP, DVD/CD-OPEN/CLOSE
The OK/ERROR display of test result is as follows.
