(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.

Remove the EEPROM and install it.

(Former board)

(New board)

Download the saved data to a machine.

(Machine after a board is replaced)

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)

Download the data.

2) Start up the application for adjustment (SEUS).

Note 1: Setting the “F orced CAMERA mode po wer ON Mode”

1) Select page: 00, address: 01, and set data: 01.

2) Select page: 2F, address: 11, and write data: E0.

3) Select page: 2F, address: 12, and write data: BC.

4) Select page: 20, address: 00, and set data: 29.

5) Select page: 20, address: 01, and write data: 29. At this time, the set is reset and the power is turns off once and then on again. Accordingly, the message “Receive Packet Error” is displayed on the SEUS screen, and the SEUS goes in “disconnect” state, but this is not a trouble. Click [Connect] on the SEUS screen to restore the “connected” state.

6) Select page: 00, address: 01, and set data: 01.

7) Select page: 2F, address: 21, and write data: 02.

The above procedure will enable the camera power to be turned on. After completing adjustments, be sure to exit the “Forced CAMERA mode power ON Mode”.
