List of Adjustment Items
The following table shows the adjustment items, their purposes, and whether or not check is required after replacing major
components.
The components shown in the table below are the minimum to be checked after replacing major components: If several
components have been replaced - or depending on the cause of a defect - more components may need to be checked.
: CHECK
*1: When replacing the PC circuit board (containing EEPROM) or EEPROM, be sure to perform all adjustments
only after "Data Initialize".
*2: Since all adjustments must be performed any time "Data Initialize" is done, do not perform it indiscriminately.
*3: For the color video camera (TYPE S/SE).
