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).
4
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.
5
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).
6
After the AVC center startup, the display side power LED starts blinking in green within 10-20 seconds.
7
Wait until the display side power LED stops blinking, the AVC center restarts automatically, and the normal
startup screen appears on the display (it will take 2-3 minutes).
8
Shut off the AC power to the AVC center (unplug the AC power cable), and remove the SD card for version
upgrade.
9
Now the software version upgrade is complete.
~
When you are done with the software version upgrade, start the unit, go to the top page of the adjustment
process screen and check the monitor microcomputer software version information.
