The data can be copied/erased by the operations on the HOME screen. (When erasing the data, execute formatting the internal memory.)
Note 1:
When replacing the SY-169 board, erase the data in internal memory of the board before replacement.
Note 2:
When replacing the SY-169 board, execute formatting and initialize the internal memory after replacement.

1-5. HOW TO WRITE DATA TO INTERNAL MEMORY
Usually, the camera has been set so as to disable the data writing from the PC to the internal memory of the camera.
This setting must be changed temporarily when the data is to be written to the internal memory such as a case after the board replacement.
To change the setting, use the write enable tool “WriteEnableTool.exe”.
This setting must be changed temporarily when the data is to be written to the internal memory such as a case after the board replacement.
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.
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 FOR REPAIR
• Make sure that the flat cable and flexible board are not cracked of bent at the terminal.
Do not insert the cable insufficiently nor crookedly.
• When remove a connector, don’t pull at wire of connector. It is possible that a wire is snapped.
• When installing a connector, don’t press down at wire of connector.
It is possible that a wire is snapped.
• Do not apply excessive load to the gilded flexible board.
Cut and remove the part of gilt
which comes off at the point.

DISCHARGING OF THE ST-160 BOARD’S CHARGING CAPACITOR (C901)
The charging capacitor (C901) of the ST-160 board is charged
up to the maximum 300 V potential.
There is a danger of electric shock by this high voltage when the
capacitor is handled by hand. The electric shock is caused by
the charged voltage which is kept without discharging when the
main power of the unit is simply turned off. Therefore, the
remaining voltage must be discharged as described below.
