3-2 Camera Adjustment
Note: How to adjust the camera system.
1) EEPROM stores confirmed adjustment value of each adjustment step.
2) DSP (Digital Signal Process : ICP04-MAIN BOARD) digitalizes the camera signal.
3) When changing IC404-MAIN BOARD of EEPROM, readjust main board. While changing LCD
board- and EVF board- always readjust each part.
Since EEPROM stores confirmed adjustment value of each adjustment step, readjusting must be
performed in order to store the changed data.
4) Adjust the following items after changing LENS ASSY.
a. LENS ZOOM TRACK
b. AUTO HALL
c. AUTO IRIS
5) Adjust the following items after changing EEPROM and MAIN BOARD.
