• Voltages and waveforms are dc with respect to ground
in wireless connection to the bar speaker (SA-CT380/
CT381).
no mark : POWER ON
• Voltages are taken with VOM (Input impedance 10 M
).
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.
