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 (please use a software version after ASTN_UQ17U_xxx.USB).
• Monitor microprocessor software (please use a software version after ASTNMxxx.SMB.)
The main software, 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, 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 supports)
• 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 ASTN_UQ17U_xxx.USB 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 into the service socket.
3. Plug in the AC cord with power button pressed down.
4. After 5 seconds, unpress the power button.
5. After the unit startup, the system upgrade screen as shown below within 20-40 seconds.

6. Even a single failure in the process will trigger the upgrade failure screen.

NOTE: In the event of a failure, repeat the upgrade process. If the process repeatedly fails, it is likely that the hardware need fixing.
7. 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.

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 main software version information.

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”.
