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 ANA circuit board (containing 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: Wit stabilizer adjustment, simply write the average value of camera correction value (at the factory) in the
adjustment program contained in floppy disk to EEPROM, and do not perform any other adjustment
indiscriminately.

Adjustment
Purpose of Adjustment
Initilizing EEPROM.
To measure the delay time in the
Sampling Pulse IC and set to optimal
pulse timing.
To set the iris control data.
To measure the time until the shutter
closes, thereby setting the still image
exposure control data.
To input the automatic wihite balance
control data.
To set the color saturation under the
reference color temperature.
To set the out-of -focus correction level
during zooming.
To set the noise level in the autofocus
circuit.
To enter the average value of camera
shake correction data.
To correct spot noise.
