Updating starts automatically and the LED on the download jig lights.

of approx. 0.8 sec.). The LED starts blinking in approx. 15 sec. since the update starts. It is

check the following items. Then, clear the problem and restart updating from the beginning.
• Is the download jig connected properly?
• Is the ROM installed to the download jig properly?
• Is the updating data written on the ROM of the download jig properly?
• Do the download jig and the equipment operate properly?
