Fully functional usable service manual. Considering the age of the manual and device quality was better than expected
 ;
Thank you very much, I've been very happy to find this manual on "Owner Manual". It's a perfect copy and it has been really useful for my work!
;
It took about 24-hours after my payment before I was able to get to the download. Apparently, payment processing is not 100% automated. That is no big deal, just be aware of that going in.
After I got to it, it was in good shape, easy to read, etc. Not some cheap FAX copy looking thing.
Also, this site was the cheapest I found. Another Plus!
;
Good price, very legible manual, exactly what I needed -- but had to wait a day to actually get the download of the manual. Would have preferred to download it immediately after payment rather than waiting for someone to "process" my order. I was surprised that I had to wait that long.
;
As the only source for this manual it rather rank quite high since it is well scanned and perfectly readable.

Connect a digital voltmeter to the TP51 on RX BASE board and the foot of FE board shield case. Connect REC out plug (P1) to an oscilloscope. Set the [RF CHANNEL] switch (SW1) to [1]. Adjust CT1 on the RX BASE board so that the value of digital voltmeter becomes 1.4 V. Confirm that the waveform of oscilloscope is sine wave. Change the carrier frequency of SSG to 864.2 MHz. Change the [RF CHANNEL] switch (SW1) to [2]. Adjust CT2 on the RX BASE board so that the value of digital voltmeter becomes 1.4 V. Confirm that the waveform of oscilloscope is sine wave. Change the carrier frequency of SSG to 864.6 MHz. Change the [RF CHANNEL] switch (SW1) to [3]. Adjust CT3 on the RX BASE board so that the value of digital voltmeter becomes 1.4 V. Confirm that the waveform of oscilloscope is sine wave.
