SOFTWARE UPGRADE PROCESS
- The adjustment values are set to the optimum conditions at the factory before shipping. If a value should become improper or an adjustment is required due to part replacement, make an adjustment according to the following procedure.
When replacing the following units,
make sure to prepare the new units loaded with updated software. MAIN Unit: DUNTKE373FM03.
UPGRADING OF EACH MICROPROCESSOR SOFTWARE
CAUTION:
Never “POWER OFF” the unit when software upgrade is ongoing. Otherwise the system may be damaged beyond
recovery.
The model employs the following
software.
- Main software
- Monitor microprocessor software.
- The main software and the monitor microprocessor software can be upgraded by using a general-purpose USB Memory.
- The followings are the procedures for upgrading, explained separately for the main software, and the monitor microprocessor software.
MAIN SOFTWARE VERSION UPGRADE
NEEDS:
- USB Memory of 128MB or higher capacity.
- PC running on Windows 98/98SE/ME/2000/XP operating system.
- USB Memory reader/writer or PC with a USB port.
- The file system of a USB memory is FAT. (FAT32 is not applied)
- Use the USB memory without other functions. (lock and memory reader...etc)

necessary to get ready the USB Memory for version upgrade before you start.
Follow the steps below and create
the USB Memory for version upgrade.
- Copy the file SAL2Axxx.USB (named temporarily) for version upgrade to the root directory (folder) of the USB Memory.
NOTE: In the USB Memory drive, do
not store other folders or unrelated files, or more than one file for version
upgrade. Now the USB Memory for version
upgrade is ready.
- Unplug the AC cord.

NOTE: In the event of a failure,
repeat the upgrade process. If the process repeatedly fails, it is likely that
the hardware need fixing.
- Upon completion of the whole process, the upgrade success screen as shown below appears. You can check the new software version on this screen. The version information appears after the upgrade is complete.
- Unplug the AC cord and remove the USB Memory for version upgrade.
- Now the software version upgrade is complete.
MONITOR MICROPROCESSOR SOFTWARE VERSION UPGRADE
- Create the USB memory for monitor microprocessor software version upgrade in the same manner as explained in the “Main software version upgrade”.
- Copy the file SAL2VAxx.USB and SAL2Mxxx.BIN (named temporarily) for monitor microprocessor software version upgrade to the USB memory.
- Unplug the AC cord.
- Insert the USB memory for version upgrade (prepared as above) into the service socket located Right side from center at terminals, above HDMI4 terminal in the rear of the unit.
- Plug in the AC cord with power button pressed down.
- After 5 seconds, unpress the power button.
- Up on completion of the whole process, power and OPC LED will blink alternately. Also, the upgrade success screen will be shown as below.
- Unplug the AC cord and remove the USB Memory for version upgrade.
- Now the software version upgrade is complete.
ENTERING AND EXITING THE ADJUSTMENT PROCESS MODE [SERVICE MODE]
- Before entering the adjustment process mode, the AV position RESET in the video adjustment menu.
- While holding down the “VOL (–)” and “INPUT” keys at a time, plug in the AC cord of the main unit to turn on the power. The letter “<K>” appears on the screen.
- Next, hold down the “VOL (–)” and “CH DN” keys at a time. (The “VOL (–)” and “CH DN” keys should be pressed and held until the display appears.). Multiple lines of blue characters appearing on the display indicate that the unit is now in the adjustment process mode. When you fail to enter the adjustment process mode (the display is the same as normal startup), retry the procedure.

adjustment process mode. If the
settings are tampered in this mode,
unrecoverable system damage may result.
