SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.

1-4. METHOD FOR COPYING OR ERASING THE DATA IN INTERNAL MEMORY
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-189 board, erase the data in internal memory of the board before replacement.
Note 2: When replacing the SY-189 board, execute formatting and initialize the internal memory after replacement.
Method for Copying the Data in Internal Memory
Copy
Copies all images in the internal memory to a "Memory Stick Duo".
1 Insert a "Memory Stick Duo" having sufficient free capacity.
2 Select [Copy] with v/V on the control button, then press z.
The message "All data on internal memory will be copied" appears.
3 Select [OK] with v, then press z.
Copying starts.
To cancel copying
Select [Cancel] in step 3, then press z.
· Use a fully charged battery pack. If you attempt to copy image files using a battery pack with little
remaining charge, the battery pack may run out, causing copying to fail or possibly corrupting the data.
· You cannot select images to copy.
· The original images in the internal memory are retained even after copying. To delete the contents of the
internal memory, remove the "Memory Stick Duo" after copying, then format the internal memory
([Format] in [Internal Memory Tool]).
· A new folder is created on the "Memory Stick Duo" and all the data will be copied to it. You cannot
choose a specific folder and copy images to it.
· The (Print order) marks on the images are not copied.
Method for Formatting the Internal Memory
This item does not appear when a "Memory Stick Duo" is inserted in the camera.
Format
Formats the internal memory.
· Note that formatting permanently erases all data in the internal memory, including even protected images.
1 Select [Format] with v/V on the control button, then press z.
The message "All data on internal memory will be erased" appears.
2 Select [OK] with v, then press z.
Formatting starts.
To cancel formatting
Select [Cancel] in step 2, then press z.

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".
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.
