To change the setting, use the write enable tool “WriteEnableTool.exe”.
Data writing method
1) Connect the PC to the camera (USB mode: Mass Storage), and switch the driver to the “Sony Seus USB Driver”.
2) Start the Write Enable Tool and the SeusEX.
3) Click the [Activate Write Enable Mode] button of the Write Enable Tool.
4) Upon completion of the setting change, the following message will be displayed.
5) Return the driver to the original one, and connect the PC to the camera (USB mode: Mass Storage).
6) Write the data read out into the PC to the internal memory of the camera.
7) Disconnect the PC from the camera, and turn off the camera.
Note: By turning off the camera, the write enable setting is reset.

1-2. ADJUSTMENT PROGRAM
The DSC-T20/T25 is adjusted by the Automatic Adjustment Pro-
gram. The Automatic Adjustment Program enters automatically
via the SeusEX the adjustment operations that were formerly en-
tered manually by the adjustment remote commander (some items
may be adjusted by manual operation on the operation screen of
the SeusEX).
1. Precautions When Using Automatic Adjustment
Program
1) TheAutomatic Adjustment Program writes the adjustment re-
sults such as EVR data to the set through two-way communi-
cation with the camera via the SeusEX. Accordingly, the Au-
tomaticAdjustment Program must be used in the environment
where the SeusEX operates.
2) TheAutomaticAdjustment Program cannot be used when the
SEUS or the SeusCam is running. Exit the SEUS or the
SeusCam before using the Automatic Adjustment Program.
3) The SeusEX must be already started on the PC when using the
AutomaticAdjustment Program.With the SeusEX not started,
some adjustment items will take time in adjustment.
4) The program run time may vary depending on the environ-
ment of the personal computer used.
2. Start of Automatic Adjustment Program
Double-click the application file (DSC-T20_T25 Auto-Adj
Ver_1.0r01.exe), and theAutomaticAdjustment Program will start.
