● 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.

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.

up.
* According to the internal software specifi 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.
