Precautions for Replacement of CCD Imager
•The CD-425 flexible board mounted as a repair part is not
equipped with a CCD imager.
When replacing this board, remove the CCD imager from the
old one and mount it onto the new one.
• If the CCD imager has been replaced, carry out all the
adjustments for the camera section.
• As the CCD imager may be damaged by static electricity from
H
its structure, handle it carefully like for the MOS IC.
In addition, ensure that the receiver is not covered with dusts
nor exposed to strong light.
EVR Data Re-writing Procedure When Replacing Board
The data that is stored in the repair board, is not necessarily correct.
Perform either procedure 1 or procedure 2 or procedure 3 when replacing board.
Procedure 1
Save the EVR data of the machine in which a board is going to be replaced. Download the saved data after a
board is replaced.

(Machine before starting repair)
Save the EVR data
to a personal computer.
Procedure 2
Remove the EEPROM from the board of the machine tha t is going to be repaired. Install the removed EEPR OM
to the replaced board.
PC
Remove the EEPROM and install it.

Procedure 3
When the data cannot be saved due to defective EEPROM, or when the EEPROM cannot be removed or installed, save the data from the same model of the same destination, and download it.
(Machine to be repaired)
Save the data.
(The same model of the same destination)
After the EVR data is saved and downloaded, check the

6-2. SERVICE MODE
2-1.APPLICATION FOR ADJUSTMENT (SEUS)
The application for adjustment (SEUS) is used to change the coefficient for calculating the signal processing or EVR data. The SEUS
performs two-way communication between PC and set through
the USB terminal. The two-way communication result data can be
written to the nonvolatile memory.
2-1-1. Using Method of SEUS
1. Connection
1) Connect the HASP key to the USB terminal of the PC.
2) Connect the PC and set with the USB cable.
3) Confirm that the set starts in the USB mode.
4) Start the SEUS on the PC.
5) Click [Connect] on the SEUS screen. If the connection is normal, the SEUS screen will be as shown in Fig. 6-2-1, indicating the
“connected”state.
Note: The SEUS will go in
turned off (for instance, by resetting the set). In such a
case, click [Connect] on the SEUS screen to restore
the
“connected”state.
“disconnect" state, if the set is
2. Operation
•Page change
To change the page, click [Page] on the SEUS screen and enter
the page to be changed. The page is displayed in hexadecimal
notation.
• Address change
To change the address, click [Address] on the SEUS screen and
enter the address to be changed. The address is displayed in
hexadecimal notation.
• Data change
To change the data, click [Set] on the SEUS screen and enter
the data. The data is displayed in hexadecimal notation.
This operation does not write the data to the nonvolatile memory .
• Data writing
To write the data to the nonvolatile memory, click [Write] on
the SEUS screen and enter the data to be written.
• Data reading
The data displayed on the SEUS screen are the data values at
the time when the pages and addresses were set, and they are
not updated automatically. To check the data change, click
[Read] on the SEUS screen and update the displayed data.
2-1-2. Precaution on Use of SEUS
Wrong SEUS operation could clear correct adjustment data. To
prevent the data clear by mistake, it is recommended to save all
adjustment data by clicking [Page Edit] on the SEUS screen before starting the adjustment.

2-2.DATA PROCESS
In some adjustment items, the calculation of SEUS displayed data
(hexadecimal) is needed to check the specified data or to acquire
the adjustment data. In such a case, prepare a computer capable of
calculating hexadecimal numbers.
Also, the data at two addresses are read, which are treated as 2
bytes of upper 1 byte and lower 1 byte (4-digit hex. number), to
check the specified data.

• Before setting the data, select page: 00, address: 01, and set
data: 01.
• In the case of page 2F, writing the data by clicking [Write] on
the SEUS screen causes the data to be written to the nonvolatile
memory. In this case, the Test mode is not released even if the
set is turned off, thus requiring extreme care.
• After the adjustment/repair finished, be sure to return the data
to “00” to restore the Normal mode. Also, select page: 00, address: 01, and set data: 00.
