ment.

Preparation

• Conditions for USB memory which can be used for updating the firmware are as follows:
- Without security function added (security function can be turned off)
- Memory with 1 GB to 2 GB are recommended (One with 4 GB or more may not oper-
ate)
- Corresponds to USB 2.0
- Formatted with FAT32 type
10.2.2

Procedure

1. Connect the USB to the PC, and copy the firmware data to the USB memory.
NOTE
• The firmware data to be updated must be copied to the root directory with the file
name "A0EDFW. tar."
• More than one firmware data with a single model or multiple models can be stored
in the USB memory. (Maximum of fifteen files)
When storing more than one firmware data, make a folder with a name "(model
code) FW" ("A0EDFW" for this machine) right under the root directory.
(File names can be set arbitrarily)
• When making a folder and storing more than one firmware data, it is also neces-
sary to copy the firmware data "A0EDFW. tar" to the root directly.
2. Turn OFF the main power switch and the sub power switch.
3. Remove the screw [1].
