SERVICE MODE
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.

Initialization to factory settings
CAUTION: When initialization is performed, all user setting data including the channel settings are initialized. Be cautious when making this adjustment.
CAUTION: When initialization is performed, all user setting data including the channel settings are initialized. Be cautious when making this adjustment.
Enter the adjustment process mode. Bring the cursor on to [INDUSTRY INIT] in page 2/32.
Set to [ON] using [VOL] key, and press [ENTER] to execute the initialization.
When the version number screen shows up on the green background and “SUCCESS”
gets displayed at the top on screen, it means the procedure has been successfully carried out.
(If an error occurs, “ERROR” is displayed on the red background.)
#Turn off the AC power.
Never shut off the power during the initialization process.

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)
CAUTION: Never “POWER OFF” the unit when software upgrade is ongoing.
Otherwise the system may be damaged beyond recovery.

# 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 as shown below appears within 20-40 seconds.

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.
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.
