When you replace to the repairing board, the written destination data of repairing board also might be changed to original setting.
Start the Adjust Manual in the Adjust Station and execute the “DESTINATION DATA WRITE”.

The unit is shipped after an ID (USB Serial No.) unique to each unit and an ID (Product ID) unique to each model have been written.
These IDs have not been written in a new board for service, and therefore they must be entered after the board replacement.
After the board has been replaced with a board for service, start the Adjust Manual in the Adjust Station and execute the “PRODUCT ID & USB 
SERIAL No. INPUT” and enter these IDs.

Note:  A newly entered Product ID is not always equal to the ID before board replacement. If the new ID differs from the previous ID, it may cause a difference 

from the ID registered by the customer.

When a board that contains Wi-Fi has been replaced or when replacing a board that contains the main IC (CPU), the IC’s unique number (MAC ad-
dress) must be reloaded.
Perform the following procedure to reload the IC’s unique number (MAC address).

Note:  Perform the following operations after all work has been done.

1.  Download the latest-version Adjust Manual.
2.  Install the downloaded Adjust Manual.
3.  Start the Adjust Manual, and execute “Wireless LAN Setting (MAC Address)” on the ADJUST tab.

Applicable parts
•  SY-1039 BOARD, COMPLETE (SERVICE)

Note:  The LOAD AND WRITE function in ADJUSTMENT DATA BACKUP on the DATA tab in the Adjust manual overwrites all data of the unit.
 

Therefore, the MAC address updated during the above procedure is also overwritten.

After the replacement and repair, the MAC address is changed, and thus the re-setting for connection devices is required. Accordingly, download the 
Flyer of WLAN Reset (Flyer of WLAN Reset_9834752[][].pdf) and print out it, and attach it to the set when returning the set to customer.

Adjustment values of each EVF display device (LCD902) are stored on the SY board.
