I found the manual to be clear concise and complete. It was of immense assistance when removing the unit as the unit was over 22 years old and the wiring diagram was unobtainable from the manufacturer. The exploded drawings were clear as were the instructions and labels.
� U : B+ Line. � Power voltage is dc 14.4V and fed with regulated dc power supply from Master unit. � Voltage and waveforms are dc with respect to ground under no-signal conditions. no mark : PB � : Impossible to measure � Voltages are taken with a 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. � Signal path. E : PB for printed wiring boards � X : parts extracted from the component side. � Y : parts extracted from the conductor side. � r : Through hole. � b : Pattern from the side which enables seeing. (The other layer�s patterns are not indicated.) Caution: Pattern face side: (Side B) Parts face side: (Side A) Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated.
