Precautions Upon Replacing CCD imager
• The CD-436 board mounted as a repair part is not equipped
with a CCD imager.
G
When replacing this board, remove the CCD imager from the
old one and mount it onto the new one.
• If the CCD imager has been replaced, carry out all the
adjustments for the camera section.
• As the CCD imager may be damaged by static electricity from
its structure, handle it carefully like for the MOS IC.
H
In addition, ensure that the receiver is not covered with dusts
nor exposed to strong light.
