List of Adjustment Items
4.1
Adjustments Needed After Replacing Major Components
The following table shows the adjustment items, their purposes, and whether or not adjustment is required after replacing
major components (items with a circle mark must be adjusted).
The items shown in the table below are the minimum that must be adjusted after replacing major components: If several
components have been replaced - or depending on the cause of a defect - more items may need to be adjusted.
(After replacing numerous components, make sure that all adjustments are correct.)
*1: When replacing EEPROM or the board containing EEPROM (MAN board), be sure to perform "Data Initialize".
(Normally, "Data Initialize" is not necessary after replacing components.)
*2: Do not perform "Data Initialize" indiscriminately.
Since the data in EEPROM will be initialized (adjustment data is initialized) by "Data Initialize", all adjustments must be
performed thereafter.
*3: Do not perform "Stabilizer" adjustment indiscriminately.
Performing "Stabilizer" adjustment will write the camera shake correction value stored on adjustment floppy disk to
EEPROM. The camera shake correction value stored on adjustment floppy disk is an average of several hundred products
(several thousand products) adjusted at factory during production: It is not a value inherent in individual products.
*4: Perform the "Spot Noise" adjustment in the following cases:
When replacing components for which it is specified that adjustment is necessary after replacing them in the above
table
When white spot occurs under unusual use conditions or during use for extended period of time
*5: The "B MATRIX" adjustment applies only to the following models:
DZ-MV200A/MV200A(K)
DZ-MV208E(AU)/MV208E(SW)
DZ-MV200E/MV200E(UK)
