--- Cautions on Firmware Update ---
When an error code as shown above appears in the DISPLAY, check the following:
• Check whether the Firmware downloaded to the USB memory is correct (whether the MODEL name and area of the
downloaded Firmware match those for the product, and whether the USB Memory contains data other than the latest
Firmware).
• Update after resetting the product.
• Use a different USB memory.
