from the microphone of the handset (CIDIN, CIDIP) is cut and the microphone signal from the
headphone is input to pin 47 of IC201 (HMIN). Also the power for the microphone is supplied from

14.5. Reception Signal Circuit
The received signal from the base unit is output from pins 33 (SPN) and 32 (SPP) of IC201 (DSP)
as the voice signal. SPN is the inverse output of SPP, and the speaker is driven by SPN and SPP.
CN203 is the headphone jack. When the headphone is connected to this jack, the output to the
speaker of the handset (SPN,SPP) is cut and the voice signal is output to the headphone
(HSOUT) only.
