Thank you very much
 ;
Exactly what was needed to assess the product - excellent value and great service
 ;
A site where discontinualed schematic diagrams and back dated information can be found on discontinued radios tv's and any electronic equipment can be found. Newer manuals either Service and operating manuals. Radio amateurs should find this site a great source for ham radio equipment manuals. I will return to this site should I need information on any electrical equipment. priced easy to download in a PDF format and print pages need to undertake the repair.
 ;
Quality scan of the original. All the detail necessary to troubleshoot, repair and adjust the unit. I'm sure I will be downloading more manuals in the future as the need arises.

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.
