To carry out a Flash ROM firmware update of the fax control PCB, follow the steps below.
This firmware update requires the following tools:

Caution:
• Turn the main power switch off and disconnect the power plug from the wall outlet before disconnecting or inserting
connectors.
• When writing data to Compact Flash card from a computer, be sure to format it in advance.
(For formatting, insert a Compact Flash card and select a drive.)

4. Insert a Compact Flash card containing the boot
