• Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum capacitor, because
it is damaged by the heat.
• Some chip part will be indicated as follows.

Note on the CCD imager replacement
• The CCD imager is not mounted for the already mounted
CD-190 board supplied as the repair parts.
When replacing the CD-190 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.
• For Printed Wiring Boards.
• Chip transistor
There are few cases that the part isn't mounted in this model is
printed on this diagram.

4-2. PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
• Measuring conditions voltage value and waveform.
• The object is color bar chart of pattern box.
• Voltages and dc between ground and measurement points.
Readings are taken with a digital multimeter (DC 10M
Ω
).
• Voltages variations may be noted due to normal production
tolerances.
