Before starting adjustments

Method for Copying or Erasing the Data in Internal Memory (Internal Memory/Music)

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-170 board, erase the data in internal memory of the board before replacement. Note 2: When replacing the SY-170 board, execute formatting and initialize the internal memory after replace-

ment.

Method for copying the data in internal memory

Copy

1 Insert a “Memory Stick Duo” having 32MB or larger capacity. 2 Select [Copy] with v/V/b/B on the control button, then press z.

The message

3 Select [OK] with v, then press z.

Copying starts.

To cancel the 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 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 DPOF (Print order) mark is not copied.

“All data in internal memory will be copied” appears.

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 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 complete.

To cancel the formatting

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

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.
