Data

At the repair, if the VC Board or EEPROM (IC2303) is replaced and the HDD is used without replacement, executing
the “Initialization of AV Index Information” of the automatic adjustment program may cause the following symp-
toms:
• Images recorded in HDD cannot be displayed on the camcorder
• Remaining capacity of HDD is incorrect
When the HDD is normal and only the VC Board or EEPROM (IC2303) is replaced for repair, perform the following
work to make the information consistent between HDD and VC Board.

Note:
• If the images recoded in HDD can be seen after the VC Board replacement, perform the HDD serial number input

in procedure 9) only.

• If the data recorded in HDD need not be restored and both VC Board and HDD are replaced at the same time,

perform “HDD replacement procedure” in 1-4. HDD SYSTEM ADJUSTMENT.
In this case, the HDD is initialized and the recorded data are erased.

• For the AV index writing software “avircst.exe”, search it with the model name and download it from the ESI site.

Procedure:
1) Before repair, back up all data in HDD to the PC.

(The data are not necessarily saved, but just in case an accident such as mishandling occurs during the repair. Be
careful for handling personal information.)

2) After the VC Board was replaced for repair, restore the data to HDD as necessary.

(USB mass storage connection)

• Perform “Exif Model Data Check” mentioned below, and also the adjustment items necessary after VC Board re-

placement.

• If the VC Board is replaced at the repair and the HDD is not replaced but used as it is, follow the “Precaution on

Replacing VC Board or EEPROM (IC2303) without Replacing HDD”.
