Value in ( ) is indicated only in the case PB
voltage is different from that in REC mode.
Waveform: Gray scale illuminated at more than 4000 lux at In the above example, CN11 is connected with CN11 on
3200K lighting. 1 1 ISB board.
· Unit of value
Unless otherwise specified
· Signal flow on the diagram
1) Resistance is in (1/6 W)
The following allow marks indicate the specified signal paths
2) Capacitance is in µF
respectively.
3) Inductance is in µH
· Expression of wiring : Recording or EE signal path
As the following circuit diagram is divided to print on some : Playback signal ptah
sheets, such an indication as the following is found in the case : Recording and Playback signal path
the wiring extends over two or more divided sections.
1) Circuit diagram divided into two or more sections: · Others

2) Indication of wiring which extends to another section:
(Example)
This indication that wiring extends to
A) "2/3" of the diagram.
DSP_HD 2/3
Signal name
In the above case, the end of the wiring is connected to
the "DSP_HD" on the 2nd section of the diagram.
This indication that wiring extends to
B) "DV I/O" section of the diagram.
FRP DV I/O
Signal name
In the above case, the end of the wiring is connected to
the "FRP" on the "DV I/O" section of the diagram.

REPLACING SURFACE MOUNT "CHIP" COMPONENTS [2] Chip transistors and chip F.E.T.s
· Some resistors, shorting jumpers (0 resistance), ceramic
capacitors, transistors, and diodes are chip parts. These chip
2SA 2SC
parts cannot be reused after they are once removed.
2SB 2SD
· Chip resistors used in some circuits are of high precision C C
type having little error in resistance.
To demonstrate the full capacity of this set, place an order
for proper parts referring to the diagrams and parts lists in
the section 5.

· Soldering cautions: (Top view) (Top view)
1) Do not apply heat for more than 3 seconds.
2) Avoid using a rubbing stroke when soldering. 2SK 2SJ
3) Discard removed chips; do not reuse them. G G
4) Supplementary cementing is not required.
5) Use care not to scratch or otherwise damage the chips.
