Great manual very clear copied. You are making an incredible job. I appreciate a lot the rapidity and your efficiency. Thanks a lot
;
Good pdf of the service manual for this unit. Includes disassembly instructions, full schematics, board layouts, parts lists and diagnostic information. Some information is in the pdf twice (single pages, and split pages), but that could be how it was originally generated by panasonic, or perhaps the idea is to make it eaiser to put onto 8.5 x 11" pages.
Information was exactly what I needed. Delivery was overnight (less than 12 hours) and I was happy with the process.
;
5 STARS for FAST DELIVERY, BEST PRICES and QUALITY PRODUCT. Item was exactly as described with superb resolution. Will definitely source all my future requirements from this website. Thanks a lot owner-manual.com!
;
OEM manual provided all schematics, board layouts and component specs necessary to facilitate unit maintenance. All pages were clear and readable.
;
Good condition and quality. Hard to find anywhere in Internet, only on this site.
SECTION 3 ELECTRICAL ADJUSTMENTS
FM section Setting BAND switch : FM
FM RF signal generator 0.01µF Set 22.5 kHz frequency deviation by 400 Hz signal Output level : as low as possible
0 dB=1µV
� This adjustment should be executed after MW band adjustment is completed because the LW and SW bands use the BAR ANT and CV1 in common with the MW band. Therefore, if MW band is adjusted, the LW and SW bands must also be readjusted. FM FREQUENCY COVERAGE ADJUSTMENT Adjust for a maximum reading on Level meter. L7 CT1-4 87.3MHz (75MHz) 108.3MHz (109.5MHz)
telescopic antenna input
FM TRACKING ADJUSTMENT Adjust for a maximum reading on Level meter. L6 87.3MHz (75MHz) CT1-3 108.3MHz (109.5MHz)
MW/LW section Setting BAND switch : MW/LW
AM RF signal generator Put the lead-wire antenna close to the set. 30% amplitude modulation by 400 Hz signal Output level : as low as possible
MW FREQUENCY COVERAGE ADJUSTMENT Adjust for a maximum reading on Level meter. L4 520kHz CT1-2 1,650kHz
MW TRACKING ADJUSTMENT Adjust for a maximum reading on Level meter. L1 600kHz CT1-1 1,400kHz
SW section Setting BAND switch : SW1 � SW9
AM RF signal generator 8pF Set 30 % amplitude modulation by 400 Hz signal Output level : as low as possible
AM IF ADJUSTMENT Adjust for a maximum reading on Level meter. T1 455kHz LW FREQUENCY COVERAGE ADJUSTMENT Adjust for a maximum reading on Level meter. L5 CT3 137kHz 295kHz LW TRACKING ADJUSTMENT Adjust for a maximum reading on Level meter. L2 155kHz CT2 260kHz
telescopic antenna input
Level meter 32� Set
Headphones jack (J1)
� Preparation for SW band adjustment After making sure that the MW band adjustment has completed, set the pointer to the center of character of 6.0, 7.2, 11.8 or 21.6MHz which is reference position of dial character, and fix the CV1 at this position. ( ) : Tourist model
� Repeat the procedures in each adjustment several times, and the frequency coverage and tracking adjustments should be finally done by the trimmer capacitors.
