: Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
• Through hole is omitted.
• Circled numbers refer to waveforms.
• There are few cases that the part printed on diagram
isn’t mounted in this model.
• Chip parts.
(For schematic diagrams)
• All capacitors are in mF unless otherwise noted. pF : m mF. 50V or
less are not indicated except for electrolytics and tantalums.
• Chip resistors are 1/10W unless otherwise noted.
kW=1000W, MW=1000kW.
• 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.
Example C541 L452
22U 10UH
TA A 2520
• Constants of resistors, capacitors, ICs and etc with XX indicate that
they are not used.
In such cases, the unused circuits may be indicated.
• Parts with
*
differ according to the model/destination.
Refer to the mount table for each function.
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
• Signal name

(Measuring conditions voltage and waveform)
• Voltages and waveforms are measured between the measurement
points and ground when camera shoots color bar chart of pattern
box. They are reference values and reference waveforms. *
(VOM of DC 10 MW input impedance is used.).
• Voltage values change depending upon input impedance of VOM
used.)

2. Adjust the distance so that the output waveform of Fig. a and the
Fig. b can be obtain.

Precautions Upon Replacing CCD Imager
• The CD-193 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.
For printed wiring boards
• This board is six-layer print board. However, the pat-
terns of layers two to five have not been included in the
diagram.
• Chip parts
Transistor
There are few cases that the part printed on this
diagram isn’t mounted in this model.
