Thank you very much. the Instruction corresponds to my expectations. Sent it in time. I don't regret that paid money.
;
Good quality. Quick service. I recommend to everyone.
;
Very good quality scan of the document. I am very pleased with what I got.
;
PDF Contains
Technical Data, Mechanical data, Detailed Circuit diagram with components value, PCB layout. Actual PCBs Print. Component List, Spare parts code list and Input output detail. It cover LBB1211, LBB1212, LBB1213, LBB1216, LBB1217.
It is the actual Service Manual for SQ10
;
very good manual with clear electrical schemes. Very helpful to find wat was wrong inside my microwave.
SECTION 6 DIAGRAMS
6-1. CIRCUIT BOARDS LOCATION THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this necessary note is printed in each block.)
For schematic diagrams. Note:
� 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. � % : indicates tolerance. � ¢ : internal component. � 2 : nonflammable resistor. � 1 : fusible resistor. � C : panel designation. Note: The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. � � � � � U : B+ Line. V : B� Line. H : adjustment for repair. Voltages and waveforms are 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. Waveforms are taken with a oscilloscope. Circled numbers refer to waveforms. Signal path. J : CD c : DIGITAL OUT
