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.

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.
(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".

If the writing method is not correct, the normal setting cannot be performed.
