into the unit IPU. A Flash Card is used instead of an
EPROM. Normally, a Flash Card update is not re-
quired and the message above will be displayed.
If the operating software is to be updated, insert the
Flash Card into the Flash Card input port. Turn off the
unit switch and set the FLASH CARD UPDATE TO
“ENABLED” using the ↑ and ↓ keys.
