Note on the CCD imager replacement
• The CCD imager is not mounted for the already mounted
CD-181 board supplied as the repair parts.
When replacing the CD-181 board, remove the CCD imager
from the old board and install on the new board.
• Perform all adjustments of the camera block when the CCD
imager has been replaced.
• Handle the CCD imager with attention such as MOS IC as it
may be broken by static electricity in the structure.
Also, prevent the receiving light section from dust attached
and strong light.
