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.

Procedure 1. Connect the Choronometer to TP218. 2. Connect the B/U and ACC line, and Turn on the ACC switch. 3. LCD display change Ver.---, While holding the buttons of MENU,M1,M5 and POWER. 4. Adjust TC201 so that an output of TP218 becomes 0.0 +0.2/-0.0Sec./day. 1. Input the 98.1MHz/55dBu(1kHz 22.5kHz Div.) SSG signal. 2. Set the output to 0dBm(1V)by main volume. 3. Adjust VR102 so that the output level is -18+3/-3dB down when the output of SSG is set to -20dBu. Connect the SSG to Main antenna (Red) side. Set the minimum VR101. Input the 98.1MHz/1kHz 22.5kHz(30%) Div. SSG signal. Input the 26dBu SSG signal and adjust VR101 so that an output of TP101(DIVADJ) becomes High from Low. 5. Confirm that TP101(DIV-ADJ) becomes Low from High within about three seconds of input the 22dBu SSG signal. 6. Confirm that TP101(DIV-ADJ) becomes 10.0V from 2.0V within about one second of input the 30dBu SSG signal. 7. Confirm that TP101(DIV-ADJ) is as follows 1.0V within five seconds of input the 20dBu SSG signal.
