Adjustment Data Backup And Restoration For Main Board Replacement - Samsung NV24HD Service Manual

Ⅴ. ADJUSTMENT

2. Adjustment Data Backup and Restoration for Main Board Replacement

A. Purpose
The purpose of the backup and restoration of adjustment setting data, when replacing the camera main
board, is to maintain the adjustment settings for an individual camera that has been set up to compensate
for that camera's deviation, in order to guarantee consistent results. Take care not to enter the adjustment
setting data for a different camera in these backup and restoration procedures.
The adjustment setting data backup and restoration procedure are only for main board replacement. When
replacing a part affecting picture quality such as a lens or CCD, you have to check the result and conduct
adjustment for the new part.
B. Procedures
1. Adjustment Data Backup Using a SD Card
A. Copy the NV2_104.txt and adjust_t files in the "back up" folder of the attachment into the root directory
of the SD card and turn the camera on.
B. When the camera is turned off after completing the backup, a FLASH. DAT file should have been
created in the root directory of the SD card. The file includes the adjustment setting data of the camera.
2. Adjustment Data Restoration Using a SD Card
A. Copy the NV2_104.txt, adjust_t and FLASH.DAT files contained in the recovery folder of the
attachment into the root directory of the SD card, and turn the camera on.
B. When the restoration is complete, the AF lamp blinks once and the camera is turned off.
3. When Adjustment Data Backup Using a SD Card Fails
A. When replacing the main board because the main board is damaged so seriously that data backup is
not available, you do not have to enter data because the default adjustment setting saved in the
firmware is used. In this case,
Since the firmware that is released when an important part such as the lens or CCD is changed may
have a default setting that differs from the previous version, use the firmware that was released in the
year when the part was manufactured.
