After replacement of any PWB unit and/or IC for repair, please note the following.
• When replacing the following units, make sure to prepare the new units loaded with updated software.
MAIN Unit: DUNTKE558FM01
Upgrading of each microprocessor software
CAUTION: Never “POWER OFF” the unit when software upgrade is ongoing. Otherwise the system may be damaged beyond recovery.
Software version upgrade
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
Get ready before you start
• 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)
Preparations
To upgrade the main software, it is 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.
1. 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.
How to upgrade the software
1. Unplug the AC cord.
2. 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.
3. Plug in the AC cord with power button pressed down after 5 seconds, unpress the power button.
4. After the unit startup, the system upgrade screen appears within 20-40 seconds.
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.
After replacement of any PWB unit and/or IC for repair, please note the following.

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 SALEMxxx.BIN (named temporarily) for monitor microprocessor software version upgrade to the USB memory.
How to upgrade the software
1. Unplug the AC cord.
2. 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.
3. Plug in the AC cord with power button pressed down.
4. After 5 seconds, unpress the power button.
CAUTION: • The moment this operation is done, the upgrading of the monitor microprocessor software starts. While the upgrade is ongoing, never power off the unit. Otherwise the upgrade will fail and the system may be serious damaged beyond recovery (inability to start).
# After the monitor microprocessor software is upgraded, also perform the 'Industry Init'.
5. After the unit startup, the upgrade starts. The power led will blink continuously. Also, an upgrade screen will be shown during a minor upgrade.

Entering and exiting the adjustment
process mode
1) Before entering the adjustment process mode, the AV position RESET in the video adjustment menu.
2) 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.
3) Next, hold down the “VOL (–)” and “CH (DOWN)” keys at a time. (The “VOL (–)” and “CH ( DOWN )” 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.
4) To exit the adjustment process mode after the adjustment is done, unplug the AC cord from the outlet to make a forced shutdown. (When the power was turned off with the remote controller, once unplug the AC cord and plug it again. In this case, wait 10 seconds or so before plugging.)
CAUTION: Use due care in handling the information described here lest your users should know how to enter the adjustment process mode. If the settings are tampered in this mode, unrecoverable system damage may result.
