4-2. SCHEMATIC DIAGRAMS (ENGLISH)

JAPANESE

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 ∝F unless otherwise noted. pF : ∝ ∝F. 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	C541	L452
	22U		10UH
	TA A	2520
Kinds of capacitor
		External dimensions (mm)

Case size

•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	PB/XREC → PB/REC

•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.

•A: not use circuit

(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 for Replacement of Imager

•If the imager has been replaced, carry out all the adjustments for the camera section.

•As the 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.

When indicating parts by reference number, please include the board name.

The components identified by mark 0or dotted line with mark 0are critical for safety.

Replace only with part number specified.

Les composants identifiés par une marque 0sont critiques pour la sécurité.

Ne les remplacer que par une pièce portant le numéro spécifie.
