Since this DVD/CD system incorporates the following
automaticadjustmentfunctions, readjustment isnotneeded
when replacing the pickup. Therefore, different PWBs and
pickups can be combined freely.
Each time a disc is changed, these adjustments are
performed automatically. Therefore, playback of each disc
can be performed under optimum conditions.

∗In each test mode, “TEST” appears at the top of the FL and that shown under “Display” of the table above at the bottom.
Pressing the POWER key in the test mode will display COMPLETE for 1 second, and then cancels the test mode.
1. If the power failure occurs in each test mode, cancel the test mode and perform an operation to recover the electricity.
(To reset the unit after the electricity resumes, be sure to write in irregular data for RAM check.)
•Canceling the test mode
Since the pickup semiconductor laser can easily damaged by
the static electricity, handle the mechanism unit with care.
To prevent damage by the static electricity during
transportation, the LD terminals are short-circuited at 2 points
on the PWB. Unsolder them by a soldering iron after
completing the connection. When you return the mechanism
unit, solder the terminals again.

2. DVD Test Mode
Outline: The key code of the test mode 1 is transmitted to the DVD unit to start up the test mode. Hereafter, the system
microcomputer only sends the key code to the DVD unit. Although operations of the main unit can be commenced
in the same manner as the DVD/CD functions, nothing has to be controlled except for monitor output. Therefore,
the sound is always mute, and the SP relay of each channel is always off, too.
As the CD cover must be kept closed with a disc inserted before entering the test mode, opening and closing
operations are not required, either. (In this test mode, no opening or closing operation is required.)
The FL display shows “DVD TEST” while in the test mode, and turns off all the other segments.
Function: 1. Start up the test mode in the same manner as the DVD/CD functions, and also start the DVD unit in the normal
operation. The display shows “DVD TEST” through this test mode, and turns off all the other segments.
2.All the other function may be startedin the normal operation. Leave the muteON since no sound is to beemitted,
and the SP relay of each channel OFF.
3.AftertheDVDunitis started,thekeycode (F1h)ofthetest mode1istransmitted intheformof thecommunication
data.
4. If the status data of Byte No. 24 is set to 0Fh, the system microcomputer will communicate with the DVD unit as
usual. However, the communication data from the DVD unit does not have to be checked. The microcomputer
accepts the only keys described in the table below, and sends the key code to the DVD unit.
(No opening or closing operation is required.)
5. “COMPLETE” is displayed by pressing the POWER key, and the system microcomputer is reset and restarted
to cancel this test mode.

5. DVD/CD Lid Test Mode
Outline: The DVD/CD lid is opened and closed repeatedly and the number of repetitions is displayed in the FL. If the finger
jam or time over is detected while the lid is opening or closing, the lid operations is stopped and the error
indication and the number of repetitions are displayed.
Keys available in this test mode are POWER, PLAY, STOP and OPEN/CLOSE only.
Operation: 1.Afterenteringthetestmode,“TEST”isdisplayedatthetopoftheFLand“00000”atthebottom,andtheunitwaits
until the next key operation is performed.
If the DVD/CD lid is not closed, close it during this operation.
2. The test is commenced by pressing the OPEN/CLOSE key. The DVD/CD lid is controlled in the following
procedure and the FL shows the number of open/close repetitions. The test operation is repeated until the STOP
or POWER key is pressed or the error is detected.
a. Open the DVD/CD lid until the OPEN completion is detected.
b. When the OPEN completion is detected, stop the DVD/CD lid operation and wait for 2 seconds.
c. After 2 seconds, close the DVD/CD lid until the CLOSE completion is detected.
d. When the CLOSE completion is detected, stop the DVD/CD lid operation, display the counter in the FL and
wait for 2 seconds.
e. After 2 seconds, return to step a and repeat the procedure.
3. If finger jam is detected in the middle of the closing operation, or the error that the opening and closing of the lid
does not complete in 5 seconds is detected, “Er ∗∗∗∗∗ is displayed at the bottom of the FL, the motor is stopped,
and the unit enters the stand-by mode. (∗∗∗∗∗ indicates the number of repetition until the test is stopped.)
4. If the STOP key is pressed, the lid operation is stopped at that point (even in the middle of an operation). The
FL indication does not change. The interrupted operation and counting resume from the same point if the OPEN/
CLOSE key is pressed in this state.
5. Pressing the POWER key closes the lid if it is open, and the test mode is canceled to reset.
Supplementary note:
1. The counter continues endlessly. When it reaches the maximum value (99999), the counter returns to “00000”
and continues counting.
6. DVD unit ROM write test mode
Outline: ThismodeistosetthemicrocomputeroftheDVDunittothewritemodeontoFLASHROM.Inthistestmode,“TEST”
is displayed at the top of the FL and “DVD WRITE” at the bottom. All the key operations except for the POWER key
are prohibited.
Operation: 1. Set the output DVD WRITE port to “L” and the DVD +B port to “H”.
2. Other ports maintains the state at the transition to the test menu mode, and do not detect any change of input
except for SYS_STOP and RESET (communication with the DVD unit is interrupted.)
3. If the power key is pressed during this operation, the test mode is canceled and the reset process is started.

7. TUNER Test Mode
Outline: Start up the unit as set to the TUNER function in the same procedure as the normal operation. Operations and
indication after startup are identical with the normal operations. However, what is different is that the frequencies
as shown in the table below are set to the tuner preset memory in advance.
Test mode operation:
(1) After entering the test mode, start up the unit with the tuner set to the preset No. 1 station, in the same manner
as in the regular startup. When starting up, the following stations are preset which vary according to the
destination.
(2) The operation is identical with the normal operation after startup.
(3) If the POWER key is pressed, irregular data is written in the RAM check data and the microcomputer is reset.
With this operation, abnormal memory is detected during the reset process, and microcomputer settings are
initialized.
Preset memory in the TUNER TEST mode
P 1 P 2 P 3 P 4 P 5 P 6 P 7 P 8 P 9 P10
87.50 108.00 90.00 106.00 98.00 522 k 1,620 k 603 k 1,404 k 990 k
8. ASPM (RDS) Test Mode
Outline: This is to check the RDS ASPM function in the production line.This mode is started as set to the FM stereo
function. Then the receiver frequencies between 105.00MHz and 108.00MHz are scanned, and a maximum of 3
RDS stations are stored in preset memory.
Test mode operation:
(1) When the power is turned on, this mode is started at FM stereo band 106.50 MHz of the TUNER function. At the
same time, preset channels 1, 2, and 3 are set to vacant, and FM stereo 87.50 MHz is stored to ch4 – ch40.
(2) The receiver frequencies are scanned from 105.00 MHz with the ASPM key, and the ASPM operation begins.
(3) If an RDS station is received, it is stored in memory from ch1 in order. (In the ASPM test mode, PS names do
not have to be memorized. When switching channels, the frequency is displayed at the head.)
(4) Scanning stops when 108.00 MHz is reached and the unit resumes to receive FM stereo 106.50 MHz.
(5) The channel numbers and frequencies are displayed in the FL from channel 1 to channel 3 in order as the
confirmationdisplayofthe memory, after whichFMstereo 106.50 MHz reappears. (Thiscanbe displayed in the
same method as the normal tuner display.)
(6) If the ASPM key is pressed again, repeat steps (2) – (5).
(7) Scanning stops where the 3 stations are stored in memory. Perform steps (4) and (5).
(8)EveniftheASPMkeyispressedlater,itsoperationwillnotstart.Instead,“___END___“isdisplayedfor1second
and the initial indication appears.
Supplementary notes:
(1) Operations that are not explained above are to be the same as the normal ASPM operation. Therefore, in the
first scan, only the station with the strongest electric intensity among those with the same PI code is stored in
memory, and no other station is memorized. In the second scan or later, the station that is previously stored in
memory and has the same frequency will not be memorized again. However, if other stations have the same PI
codebutdifferentfrequencies,theonewiththestrongestelectricintensityismemorized.Atthattime,theelectric
intensityofthememorizedstationisignored.Byrepeatingscanning3times,3stationswiththestrongestelectric
intensity may be stored in memory, even if they have the same PI code.
(2) If the POWER key is pressed, irregular data is written in the RAM check data and the microcomputer is reset.
Withthisoperation,abnormal memory is detectedduringthe reset process, and themicrocomputersettings are
initialized.
