Very pleased with manual except that a few more details in the drawings might make the job (not yet done, tut-tut) easier. Should be adequate though. Actually I didn't have to pay for this anyway as I was given credit for another item that wasn't quite complete. Good service, then.

MDR-IF540R SECTION 4 DIAGRAMS
THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.) for schematic diagram: � All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. � All resistors are in � and 1/4 W or less unless otherwise � � � � � � specified. C : panel designation. A : B+ Line. H : adjustment for repair. Power voltage is dc 2.4 V and fed with regulated dc power supply from battery terminal. Voltage is dc with respect to ground under no-signal (detuned) conditions. Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. Signal path. F : ANALOG J : RF

for printed wiring boards: � X : parts extracted from the component side. � Y : parts extracted from the conductor side. � a : Through hole. � : 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.
