Inserting the Region Code after replacing the Main PCB

NOTE
• After replacing the Main PCB and System Micom (IC23), the region code should be inserted.
• The unit will not work properly if you do not insert the correct region code.
• You must use the remote control

Select the "AUX" mode and then press the "Tuner Memory" button on the remote control for 4-5 seconds

You should see the “T-MODE” message display on the VFD. Press the “▼” direction button during this message.
NOTE: The “T-MODE” indicator on the VFD only appears for a very short time.

You can see “TEST - -” on the VFD. Insert the number “46” to select the Region Code.

After step (3), you can see “- - -” on the VFD.
Insert the Region Code (see Table on next page) corresponding to the model and area in which you reside in using the “0-9” buttons on the remote control. And then turn off the power.

In order to check if you inputted correctly, please do Number 1, 2, 3 again and then during “TEST - -” MODE insert number 47. After that, you can check the option code which you inserted. For example, you can see “000US5”. It means that you inserted region code “000” and the region is USA which supports 5.1CH Audio output. If it is “047EU2”, it means that you inserted region code “047” and the region is Europe which supports 2.1ch Audio output.
