   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 dvd/cd lid 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 started in the normal operation. Leave the mute ON since no sound is to be emitted,
    and the SP relay of each channel OFF.
3. After the DVD unit is started, the key code (F1h) of the test mode 1 is transmitted in the form of the communication
    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.

Supplementary notes:

1. The DVD/CD lid cannot be opened or closed (loading or unloading discs) in this test mode. After loading a disc,
    turn the power off to enter this test mode.
2. Operations of keys unrelated to the DVD operations are not accepted except for the POWER key. Therefore, you
     cannot switch functions, control volume, or control DSP, etc. The controls of electronic volume IC, input selector
    of the A/D and D/A converter, and monitor output are fixed to the settings of the DVD/CD functions.

Outline:

In this test mode, all the operations except for volume control can be controlled in the same way as in the regular
power on state. The function can be switched to another, and the DVD can be played as well as the AC3 and DTS
multichannel playback, etc.
Only the volume control differs from the normal operation, and it can be changed among only 4 levels of 0, 1, 25,
and 40.

   Function:

1. After entering the test mode, start the unit as set to the VTR (VTR1) function in the same manner as the normal
    operation.
2. Start up the unit with the volume set to 25 (-16dB) and the surround set to the STEREO mode. X-BASS must be
    turned off.
3. The volume can be increased or decreased among 4 levels of 0, 1, 25, and 40 only if the volume control key input
    is performed.
4. “AMP TEST” is always displayed at the bottom of the FL. It changes to the operational indication for 3 seconds
    only when the following operations are performed. All the controls except for the display perform the same
    operations.
    • The volume level is displayed when it is changed.
    • When the X-BASS key is operated, its ON/OFF status appears.
    • The frequency appears when the function is switched to TUNER.
    • The operation is displayed for the first 3 seconds when the DVD play, stop, or pause operation is performed.
    • When various errors occur. In this case, the error is always displayed until it is restored.

Outline:

This is to check that the system microcomputer properly acknowledges the key operations on the main unit.

Operation: In this test mode, the power is supplied only for the display, and all the FL indications are turned off as in the test

menu mode.
Then, the indication of 8 digits that corresponds to the key identified by the system microcomputer is displayed in
the FL.
When the power key is pressed, the whole FL is lit for 2 seconds before its power is turned off and the test mode
is canceled.

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. After entering the test mode, “TEST” is displayed at the top of the FL and “00000” at the bottom, and the unit waits

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.

Outline:

This mode is to set the microcomputer of the DVD unit to the write mode onto FLASH ROM. In this test mode, “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.

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.
