Precautions Upon Replacing CCD imager
• The CD-541 board mounted as a repair part is not equipped
with a CCD imager.
When replacing this board, remove the CCD imager from
the old one and mount it onto the new one.
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.
In addition, ensure that the receiver is not covered with
dusts nor exposed to strong light.
In addition, ensure that the receiver is not covered with
