Precautions for Replacement of CCD Block Assy
• If the CCD block assy has been replaced, carry out all the
adjustments for the camera section.
• As the CCD block assy may be damaged by static electricity
from its structure, handle it carefully like for the MOS IC.
In addition, ensure that the receiver is not covered with dusts
nor exposed to strong light.
