I found this manual to be complete in every detail. Besides the schematic it has a complete set of alignment instructions which are easy to understand. It also includes a complete parts list as well as an explanation of how the power supply and safety shutdown circuits operate. Even a schematic of the tuner is included.
The product was good and just what I needed, however I had moderate difficulty with the down load because the sight would not recognize my pass word. I was finally given a direct link to the manual and that worked.
Very quick and easy website to use and fast download of manual, quality of manual is excellent and will be pleased to use this service again in the future, thanks so much!

*When an intercom transmission is not in use, the waveform of (D) becomes the same burst signal as (C). 2. Data Reception The data that is transmitted to the telephone line from another set is input via T701 in reverse order of the data transmission (D). This burst signal passes BPF701 to separate from the audio signal and then only 455 kHz is extracted (E) at pin 5 of IC701. This burst signal is amplified and demodulated at pin 4 of IC701 (I). The amplified burst signal (J) is input to pin 32 of the microcomputer IC801.
