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 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.
