• The CD-431 board mounted as a repair part is not equipped<br />
with a CCD imager.<br />
When replacing this board, remove the CCD imager from the<br />
old one and mount it onto the new one.<br />
• If the CCD imager has been replaced, carry out all the<br />
adjustments for the camera section.<br />

• As the CCD imager may be damaged by static electricity from<br />
its structure, handle it carefully like for the MOS IC.<br />
In addition, ensure that the receiver is not <strong>cover</strong>ed with dusts<br />
nor exposed to strong light.<br />
