(ENGLISH)
THIS NOTE IS COMMON FOR SCHEMATIC DIAGRAMS
(In addition to this, the necessary note is printed in each block)
(For schematic diagrams)
• All capacitors are in µF unless otherwise noted. pF : µ
Link
µF. 50 V or less are not indicated except for electrolytics
and tantalums.
• Chip resistors are 1/10 W unless otherwise noted.
kΩ=1000 Ω, MΩ=1000 kΩ.
• 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
Kinds of capacitor
Temperature characteristics
• 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
XEDIT → EDIT
• 2: non flammable resistor
• 5: fusible resistor
• C: panel designation
• A: B+ Line
• B: B– Line
J
• : IN/OUT direction of (+,–) B LINE.
• C: adjustment for repair.
• Circled numbers refer to waveforms.
(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 MΩ input impedance is used)
• Voltage values change depending upon input
impedance of VOM used.)
Precautions Upon Replacing CCD imager
• The CD-522 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.
