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.

qa

The DSC-T20/T25 is adjusted by the Automatic Adjustment Pro­gram. The Automatic Adjustment Program enters automatically
via the SeusEX the adjustment operations that were formerly en­tered 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) The Automatic Adjustment Program writes the adjustment re-

sults such as EVR data to the set through two-way communi­cation with the camera via the SeusEX. Accordingly, the Au­tomatic Adjustment Program must be used in the en vironment
where the SeusEX operates.

2) The Automatic Adjustment 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

Automatic Adjustment Program. W ith 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
V er_1.0r01.ex e), and the Automatic Adjustment Program will start.

3. Function of Each Button on Main Menu Screen

When the Automatic Adjustment Program started, the Main Menu
screen in Fig. 6-1-14 will appear. On this screen, select each ad­justment section.

Preparation of Flange Back Adj.
(Using the minipattern box)

1) The minipattern box is installed as shown in the following fig­ure.
Note 1: The attachment lenses are not used.

2) Install the minipattern box so that the distance between it and
the front of lens of camera is less than 3 cm.

3) Make the height of minipattern box and the camera equal.

4) Check the output voltage of the regulated power supply is the
specified voltage ± 0.01 Vdc.

5) Check that the center of Siemens star chart meets the center of
shot image screen with the zoom lens at TELE end and WIDE
end respectively.

Specified voltage: The specified voltage varies according to the

minipattern box, so adjustment the power sup­ply output voltage to the specified voltage writ­ten on the sheet which is supplied with the mini­pattern box.

Preparation of Flange Back Adj.
(Using the flange back adjustment jig)
(Luminance: about 300 lux)

Note 2: When using the flange back adjustment jig, take care of

the following points:

• For the illumination, use a light source such as an in­candescent lamp or inverter type fluorescent light free
from flickering.

• Do not make an adjustment in the environment where
fluorescent lamp flickering occurs even if the illumi­nance can be ensured with the room illumination only.
Use an incandescent lamp or inverter type fluorescent
light at a place free from the influence of room illumi­nation.

1) Install the flange back adjustment jig so that the distance be­tween it and the front of lens of camera is less than 3 cm.

2) Make the height of flange back adjustment jig and the camera
equal.

3) Check that the center of chart meets the center of shot image
screen with the zoom lens at TELE end and WIDE end respec­tively.

Perform this adjustment only when replacing the angular velocity
sensor or lens block. When the microprocessor, circuit etc. is dam­aged, don't perform this adjustment but check the operations only.

9-1. Precaution before adjustment

Before adjustment, read the following data and record them.
When the SY-170 board is replaced, read out the data before the
replacement, and record them.

Reading out method:

1) Read out the data in Block:11, Page:61, Address:0E10, and
name this as Dp.

2) Read out the data in Block:11, Page:61, Address:0E11, and
name this as Dy.

9-2. Preparation when the angular velocity

sensor or the SY-170 board is replaced

Note down the sensitivity displayed on the angular velocity sensor of
the repair parts. At this time, note down also to which board it was
attached to.
Be sure to check because if attached incorrectly, the screen will vi­brate up and down or left and right during the steady shot operations.

Precautions on the Parts Replacement

The PITCH sensor and the YAW sensor are different parts.

Preparation:

1) Read the PITCH sensor (SY -170 board SE502) sensiti vity writ­ten on repair parts, and named this as S

.
