[Preparations]
Rewriting a program needs the product to enter the in-process adjustment mode.

1) The rewriting software is supplied in the form of an exe file named e.g., "MAIN_2002_10_10A.exe" (provisional).

Create a directory on a HD and copy the software into the directory.

2) Double-click the file. The file will be self-extracted. Check the extracted file against the documentation

accompanying with the software.

3) Connect the AVC System and the display unit with each other and make them ready for operation (make sure

the power LEDs of the AVC System and display unit turn red).

4) Use an RS-232C cable to connect the PC to the AVC System.
5) Exercise great care to hide the procedure in entering the in-process adjustment mode from the customer.

Press the MAIN POWER button while holding down the volume DOWN key and the INPUT key on the display
unit simultaneously.
If blue characters appear on the display, the system has entered the in-process adjustment mode successfully.
If not (the normal activation screen opens), retry.

[Rewriting the main program]

1) In the in-process adjustment mode, press the Channel Up key on the remote controller. You will move to page

13 ("13/13" will appear on the upper left corner of the screen).

2) Make sure CENTER PROG UPDATE is highlighted.
3) Use the VOLUME -/+ keys to change OFF to ON.
4) Press the ENTER key on the remote controller. Characters on the screen will disappear and the screen blacks

out.

5) Double-click the batch file specified in the document accompanying with the software.
6) A black window (MS-DOS window) will open and rewriting starts automatically.

Rewiring of the main program is now complete. Unplug the AC cable from the AVC System and turn off the
system and then on again.

7) Enter the in-process adjustment mode and make sure the version information on the CENTER Version, OSD

Version and CVIC Version lines on page 1 has been updated.

CAUTON: Exercise great care to hide the procedure in entering the in-process adjustment mode from the
customer. Inadvertent setting changes in this mode may cause a fatal error resulting in a program being
unrecoverable.
