on the MAIN
board.
• Voltages and waveform are dc with respect to ground un-
der no-signal conditions.

• Waveform is taken with a oscilloscope.
Voltages variation may be noted due to normal production
tolerances.
• Voltages are taken with a VOM (Input impedance 10

tolerances.
• Circled number refer to waveform.

• The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
form that of conventional IC.
