How to transfer to the mode
While pressing and holding [PRESET-6] + [SEARCH], reset to transfer to the ROM correction writing-in mode.
The opening display shall be omitted for the easy recognition of the mode transfer.
In this mode, DOP setting is unavailable (Except only for DOP TYPE display).
In the old model, after the mode transfer, the operation is possible to become unstable due to the ununiformity of the respec-
tive keys’ effectiveness.
And considering the confusion due to an accidental press in the line, the keys other than [EJECT] key shall be disabled.
After entering to this mode, insert DISC and USB.
The display of the SRC switching is shown in the same manner as the display of the normal mode.
After the completion of Reading, start the Update if there is an update
fi
le.

fi
le, display “NO FILE”.
Note that the DEMO mode display in ROM correction UPDATE mode will cause the Delay of the mask or the beginning of start-
up.

According to the internal software speci
fi
cation, DEMO mode ON setting shall be disabled. And during the ROM correction
UPDATE, it shall keep initializing the timer for DEMO mode startup management.
