  Preparation

To upgrade the main software, it is necessary to get ready the SD card for version upgrade before you start.
Follow the steps below and create the SD card for version upgrade.
1 Insert the SD card into the SD card reader/writer.  Start the SD card formatting software.  Click [Format].

(When you have the drive options, select the drive where the SD card is inserted before you proceed.)

2 When the formatting is over, the following window appears.  Click [OK].

3 Click [Exit] to finish the formatting.
 ~ When you are done, take out the SD card once to make sure it is finished, and then insert it again.

4 Copy the binary image file KD1EAxxx.SDC (named temporarily) for version upgrade to the root directory

(folder) of the SD card drive.

 ~ In the SD card drive, do not put other folders or unrelated files, or more than one binary image files for version

upgrade.

Now the SD card for version upgrade is ready.

  How to upgrade the software

Software upgrading can be done regardless of whether a dedicated display is connected or not.  You can view the
progress on the dedicated display if it is connected.  When such display is not used, see the power LED on the
AVC system which blinks according to the status of upgrading.  Please note that, unlike the digital model, the
progress of upgrading does not appear on the screen of the TV set connected to the video output terminal of the
AVC system.
1  Shut off the AC power to the AVC system (i.e. unplug the AC power cable).
2  Insert the SD card for version upgrade (prepared as above) into the service socket below the CENTER

CHANNEL INPUT terminal in the rear of the AVC system, keeping the cut corner of the SD card at the right-
hand side.

 ~ If the SD card is inserted with wrong orientation, the card will go deep inside the unit beyond retrieval.  Use

due care to insert the SD card in a correct way.

3  While depressing the SYSTEM RESET button in the front of the AVC system, turn on the AC power (i.e. plug

in the AC power cable).

 ~ After the AVC system is started, you may release the SYSTEM RESET button.
4 After the AVC system startup, the system upgrade screen as shown below appears within 10-20 seconds.
