Note on Printed Wiring Board:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• b : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen from
(Side B) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Side A) the parts face are indicated.
• JK-136 (H), YC-148 (H), MA-324 (H), LC-61 (F), SW-306

• U : B+ Line.
• Power voltage is dc 8.4 V and fed with regulated dc power
supply from external power voltage jack.
• Voltages and waveforms are dc with respect to ground in
color-bar signal input.
no mark : VIDEO MODE
• Voltages are taken with a V OM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tolerances.
• Circled numbers refer to waveforms.
