(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 M� input impedance is used.). � Voltage values change depending upon input impedance of VOM used.) 1. Connection

(For schematic diagrams) � All capacitors are in µF unless otherwise noted. pF : µµF. 50V or less are not indicated except for electrolytics and tantalums. � Chip resistors are 1/10W unless otherwise noted. k�=1000�, M�=1000k�. � 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.

For printed wiring boards � This board is six-layer print board. However, the patterns of layers two to five have not been included in the diagram.

� Circled numbers refer to waveforms. Note : The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified.

There are few cases that the part printed on this diagram isn�t mounted in this model.
