Precautions Upon Replaching CCD imager
• The SY-85 board mounted as a repair part is not equipped
with a CCD imager.
When replaching 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 electrictiy from
•
Y/CHROMA
its structure, handle it carefully like for the MOS IC.
In addition, ensure that the receiver is not covered with dusts
nor exposed to strog light.
