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.

Copies all images in the internal memory to a “Memory Stick Duo”.

1

Insert a “Memory Stick Duo” having 32 MB or larger capacity.

2

Select [Copy] with v/V/b/B on the control button, then press z.
The message “All data in internal memory will be copied” appears.

3

Select [OK] with v, then press z.
Copying starts. 

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 copy individual images.

• 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 execute the [Format] command in 
[Internal Memory Tool].

• When you copy the data in the internal memory to the “Memory Stick Duo”, all the data will be copied. 

You cannot choose a specific folder on the “Memory Stick Duo” as the destination for the data to be 
copied.

• Even if you copy data, a 

 (Print order) mark is not copied

.

This item does not appear when a “Memory Stick Duo” is inserted in the camera.

Formats the internal memory.

• Note that formatting irrevocably erases all data in the internal memory, including even protected images.

1

Select [Format] with v/V/b/B on the control button, then press z.
The message “All data in internal memory will be erased” appears.

2

Select [OK] with v, then press z.
The format is completed.

Select [Cancel] in step 2, then press z.

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”.

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.

• 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.
(Be careful or some 
pieces of gilt may be left inside) 

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.

To preparing the short jig, a small clip is attached to each end of
a resistor of 1 k

Ω /1 W (1-215-869-11).

Wrap insulating tape fully around the leads of the resistor to
prevent electrical shock.

Wrap insulating tape.

 High-voltage cautions

Short-circuit between the two points 
with the short jig about 10 seconds.
