New part of EEP ROM (IC1103) on the MAIN board
cannot be used. Therefore, if the mounted MAIN board
(A-1179-147-A) is replaced, exchange new EEP ROM
(IC1103) with that used before the replacement.
• A : B+ Line.
• Voltages and waveforms are dc with respect to ground un-
der no-signal (detuned) conditions.
• Voltages and waveforms are dc with respect to ground in
service mode.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
