• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
• Signal path.

G : RECORD
J : CD PALY (ANALOG OUT)
c : CD PALY (DIGITAL OUT)
N : MIC INPUT
• Abbreviation
AR : Argentina model
MX : Mexican model
E51 : Chilean and Peruvian model
Note:
The components identified by mark 0 or dotted line
with mark 0 are critical for safety.
