CCD Imager Correction Data Write
[Dio 20 (CCD DEFECT
Perform CCD imager correction data write in the following
cases.
1. When the CCD imager has been replaced
2. The ocassion of exchaning 2 camera micro processor or
EEPROM (1C712).
3. When the page F data has been initialized
In the case of 1, as the correction data is not required for the
CCD imager for repair, adjust all data of addresses 1D to 2C to
"00".
In the case of 2 and 3, write the correction data attached to the
shield case of DD-47 board to addresses 1D to 2C.
If the correction data are not attached, adjust all data of addresses
1D to 2C to "00".
Adjusting method:
1)
Release the protect.
Page: 6, address: 00, data: 01
2)
Write the correction data to page: F, addresses: 1D to 2C.
Note: To perform write to the non-volatile memory, press
the PAUSE button of the adjusting remote control
unit before changing addresses.
Processing after completing adjustments
1)
If the CCD
imager has been replaced, remove the old
correction data label attached on the shield case (UPPER) of
DD-47 board.
