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.

Exactly what I needed to be able to bring the amp back to life... will come back to this site the next time I need schematics.
RX Section Adjustment
1. RX Level Adjustment � Perform the adjustment at T1CH (26CH: 43.780 MHz) as a rule. Setting :
FM RF SSG HAND MAIN board TP2 TP3 (RX GND)
3. RSSI (H) Sensitivity Adjustment � Perform the adjustment at T1CH (26CH: 43.780 MHz) as a rule. Setting :
AF ocillator FM RF SSG HAND MAIN board TP2 TP3 (RX GND) output: 20 Hz
Procedure : 1. FM RF SSG condition : Carrier frequency : 43.780 MHz Modulation : 1 kHz Deviation : 3 kHz Output level : 60 dBµV (1 mV) (EMF) 2. Adjust the FL101 for the maximum reading on the level meter. Also check that the output level is within the specified values.
level meter HAND MAIN board + � TP27 (SP) TP26 (SP)
Procedure : 1. FM RF SSG condition : Carrier frequency : 43.780 MHz Modulation frequency : 20 Hz (EXT) Deviation : AM 50% Output level : 2 dBµV (1.259 µV) (EMF) 2. Use the oscilloscope to confirm the FM RF SSG input (AF) signal waveform and RSSI signal, and use the RV101 so that they are synchronized matched (duty is synchronized).

0V RF signal EXT signal 20Hz Adjust so that they synchronize at 0V.
+ �
TP5 (RX VT) TP3 (RX GND)
Adjustment Location: HAND MAIN board (See page 17)
Procedure: 1. The digital voltmeter connected TP5 (RX VT) to TP3 (RX GND). 2. Adjust the L102 for 0.8 V ± 0.05 V reading on the digital voltmeter. Adjustment Location: HAND MAIN board (See page 17)
