Restore Data
When you replace to the repairing board, get the data from the former one.
Start the Adjust Manual in the Adjust Station and perform "RESTORE DATA" to get the data.
The data getting for this model is as follows.
• PRODUCT ID & USB SERIAL No.
• EVF Data Input
USB Serial No. and Product ID
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.
Update of MAC Address
When replacing a VC board, the IC's unique number (MAC address) must be reloaded.
After the board has been replaced with a board for service, perform the following procedure to reload the IC's unique number (MAC address).
Note: Perform this 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.
If "Wireless LAN Setting (MAC Address)" is not executed and the backup data before replacement is restored, the MAC address in the Wi-Fi module
does not match the MAC address in the flash memory, causing an error during Wi-Fi transfer.
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.
