How to upgrade the software
1
Shut off the AC power (i.e. unplug the AC cord).
2
Insert the SD card for version upgrade (prepared as above) into the service socket located below left of the
right side cooling fan in the rear of the unit, in a way that the cut corner of the SD card comes at the right-
hand side.
Note: If the SD card is inserted in a wrong way, the card will go deep inside the unit beyond retrieval. Take due
care to insert the SD card correctly.
3
While depressing the "SYSTEM RESET" button located below the RS-232C connector in the rear left side
of the unit, turn on the AC power (i.e. plug in the AC cord).
Note: After the unit is started, you may release the SYSTEM RESET button.
4
After the unit startup, the system upgrade screen as shown below appears within 10-20 seconds.
5
Even a single failure in the process will trigger the upgrade failure screen as shown below. The word "NG"
changes to red for the item failed.
Note: In the event of a failure, repeat the upgrading process. If the process repeatedly fails, it is likely that the
hardware is troubled.
