2.3. 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 BSMK_632-732_xxx.USB and BMSDMxxx.SMB. (named temporarily) for monitor microprocessor software version upgrade to the USB
memory.
2.3.1 How to upgrade the software
1. Unplug the AC cord.
2. Insert the USB Memory for version upgrade into the service socket.
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.
6. If the upgrade fails, power led will stop blinking. Also, the upgrade failure screen will be shown if upgrade screen was shown at 5.
NOTE: In the event of a transient failure, upgrade will be automatically retried up to three times. If the process repeatedly fails, hardware may be the
cause.
7. The upgrade success screen will be shown if upgrade screen was shown at 5.
8. Unplug the AC cord and remove the USB Memory for version upgrade.
9. Now the software version upgrade is complete.
NOTE: When you are done with the software version upgrade, start the set, go to the top page of the adjustment process screen and check the mon-
itor microprocessor software version information and panel size information.
