WRITING NEW PROGRAM TO FLASH MEMORY
Inclusion of flash memory (rewritable, nonvolatile memory) onto the control sheet had enabled the following operations.
(1) Record to and replay from the flash memory: 1MB (See "6. Operation" above.)
(2) Program change: 512KB
Version upgrade on the DKVII and DKV Silent II was implemented by changing the CTRL-ROM. On the DKV
IIXG and DKV Silent IIXG, the upgrade program is supplied on floppy disk so that it can be copied directly into
flash memory, overwriting the existing version.
NOTE: Only the controller program can be overwritten. Test, maintenance-mode, and loader programs cannot be
overwritten.
Note that this new method for updating the system program applies only to the control unit. There is no change in
the method used for updating the program on the other units.

If incorrect disk was inserted, please switch the power
off/on and start again from the beginning.
The number at the left shows the program version
currently installed in the controller. The number at
right shows the update version (the version stored in
the floppy disk).
Do not remove the floppy disk, and do not switch off
the power, while this message appears on the screen.
If you switch power off or eject the floppy disk while
upgrading is in progress, you will need to do the
following to resume normal operation: with power off,
hold down both the PLAY and PAUSE buttons and
then switch on the power. You can then restart the
upgrade from the beginning.
