Upgrading the firmware
from an external
memory device
You can load a firmware stored in a commercially-
available external memory device (USB memory
stick or microSD card) to the product to upgrade
the existing firmware. This is convenient when you
want to manage firmware versions or change the
firmware of multiple units of the product.
NOTE
• External memory devices used for the product must
be formatted in FAT or FAT32.
• You cannot use a USB hub to connect two or more
USB memory sticks or other external memory
devices to the product.
• Some types of USB extension cables may not be
able to work normally. Use the USB memory stick by
inserting it directly into the USB port of the product.
• Do not remove the external memory device while
the USB lamp or microSD lamp of the product is lit
up or flashing. Doing so may damage data in the
external device. Before removing the external device,
hold down the USB button or microSD button for
two seconds and make sure that the USB lamp or
microSD lamp has gone off.

can be upgraded from an external
memory device
In the "Startup via external memory" field on the

for upgrading.
To open the "Configure external device" screen
From "Basic configuration page", click the buttons
on the setup screen in the following order:
