Preparations for Firmware rewriting

2.1.1

Service environment

• Drive which enables writing/reading of Compact flash
• Compact flash (with 32 MB or more)
2.1.2

Writing into the Compact flash

• Copy the firmware files using the computer.
NOTE
• The copying operation should be performed on the files contained in the folder,
instead of the folder.
• Copy only those files to be upgraded to the compact flash.
• If wrong firmware is copied, no screen display is given and thus no firmware can
be downloaded.
2.1.3

Checking ROM version

• Before attempting to upgrade the firmware, check the current ROM version.
For details of how to display the Tech. Rep. Mode screen, see the Adjustment/Setting
of the main unit service manual.
