Everything was great, the manual, the response time, the simplicity of the order, and the
Price. The only thing that I could possible say on a negative note would be that the manual I ordered was more for a service tech. There were a lot of schematic diagrams that didn't help me solve the problem. However I would order again and recommend the web sight to others.

7-2. The voice of the caller cannot be heard in SP-PHONE MODE.
The 1kHz 40mV burst sine signal is applied to TEL-line of the base in SP-PHONE MODE. Can the 1kHz burst sine signal from pin 3 of T1 be fed? OK Check whether there is the 1kHz burst sine signal from pin 7 of IC5. OK Check whether there is the 1kHz burst sine signal from pin 6 and pin 20 of IC401. NG Check Q16, IC401 and their peropheral circuits. NG Check IC5 and its peropheral circuit. NG Check the base TEL line circuit and RELAY control circuit.
OK Check whether there is the 1kHz burst sine signal from pin 5 and pin 8 of IC402. OK Check J401, FC701, J752 D754, W701, W702 and SP701. NG Check IC402 and its peripheral circuit.
