5.7 Initialization to the factory shipment state
When the initialization is operated, internal information changes as follows. It is essential to obtain the client's permission before the
operation.
• All DVD library is all deleted.
• All the DVD initial settings go back to the initial status.
(1) Set to the JIG mode.
(2) Transmit "43-6F" with the JIG remote control unit.
(3) FL indicator displays "FACTORY", and changes to "CHECK OK" after blinking for a short while.
(4) Pull out the power code from the wall socket.
(5) The JIG mode is forced to cancel at the same time with the initialization, check whether the JIG mode is canceled by plugging
the power code into the wall socket again. (The colon ":" in time display should be continuously ON, not blinking.)
If the JIG mode is not canceled, transmit "43-9D" with JIG remote control unit to cancel the JIG mode.
5.8 Setting after the drive unit replacement
When the drive unit is replaced, it is necessary to set a region code. Service drive units for replacement are not set for any region
code, and they are in an indefinite condition.
Make sure to set region code after attaching the drive unit to the main body.
Without the setting of the region code, discs that have regions cannot be played back.
5.8.1 Creating a region setting disc.
Please check the details of the region setting disc creation method by JS-NET.
(1) Download the region setting file from JS-NET. The file name is "region.bin".
(2) Write the region setting file into CD-R. Pay attention in the following points when writing the file into CD-R.
• Make sure to write in "Disc at Once".
• Set the file compatibility to "ISO9660 format". (ROMEO, JOLIET are disapproved).
If the writing method is not correct, the normal setting cannot be performed.
5.8.2 Setting the region
(1) Set for the JIG mode.
(2) Load the region setting disc on the tray, and then close the tray.
(3) When the disc reading operation is completed, transmit "43-70" with the JIG remote control unit.
(4) FL indicator changes to "UPDATE". Remove the disc as the tray will open for a few seconds.
(5) Then, check whether the FL indicator is "REGION 2".
(6) Transmit "43-70" with the JIG remote control unit. When FL indicator changes to "OPEN", close the tray.
(7) Turn the power OFF, and pull out the power code, and then plug the power code in again.
(8) Cancel the JIG mode.
