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 center 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 center.

  Shut off the AC power to the AVC center (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 center, 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.

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

  How to upgrade the software
The software upgrade is performed in the environment where the AVC center is connected to the display unit
whose software is to be upgraded.  During the monitor microcomputer software version upgrade, the progress of
upgrading will appear neither on the display screen nor on the screen of the TV set connected to the video output
terminal of the AVC center.  The upgrading status is seen by the blinking of the display side power LED.
1
 Connect the display to the AVC center correctly.  Turn on the AC power of each unit (plug in the AC power
cable).
2
 Turn on the main power switch (not the receiver power switch) of the display beforehand.
3
 Shut off the AC power to the AVC center (i.e. unplug the AC power cable).
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 center, 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 correctly.
While depressing the SYSTEM RESET button in the front of the AVC center, turn on the AC power (i.e. plug in
the AC power cable).
 ~
After the AVC center is started, you may release the SYSTEM RESET button.
Caution!!
The moment this operation is done, the upgrading process of the monitor microcomputer software starts.
While the upgrade is ongoing, never turn off the power to the display or the AVC center.  Otherwise the
upgrade will fail and the system can be damaged seriously beyond recovery (inability of the display unit
startup).
