Precautions for Replacement of CCD Imager
• The CD-271 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.
• 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.
