(For schematic diagrams) � All capacitors are in µF unless otherwise noted. pF: µµF. 50 V or less are not indicated except for electrolytics and tantalums. � Chip resistors are 1/10 W unless otherwise noted. k� = 1000 �, M� = 1000 k� � Caution when replacing chip parts. New parts must bo attached after removal of chip. Be careful not to heat the minus side of tantalum capacitor, Because it is damaged by the heat. � Some chip part will be indicated as follows. Example C 541 L 452 22U 10UH TA A 2520 n n

� Microphone block is replaced as block, so that printed wiring board and schematic diagram is omitted.
� C : panel designation. � U : B+ Line. � ¢ : internal component. � Power voltage is dc 6 V and fed with regulated dc power supply from CN001 pin 1. � Voltage is dc with respect to ground under no-signal (detuned) condition. � Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. When indicating parts by reference number, please include the board name.
