KX-T2375MXW 13 CIRCUIT OPERATION 13.1. Bell Detector Circuit When the bell signal is input between T/R, the signal are outputted at the speaker via the following path: Tel line → R1/C1 → D1 → Pin 1 of IC1 → Pin 8 of IC1 → C6 → T1 → C625 → Speaker 13.2. KX-T2375MXW 13.3.

Speakerphone Circuit 13.3.1. Function The circuit controls the automatic switching of the transmitted and received signals, to and from the telephone line, when the unit is used in the hands -free mode. Circuit Operation The speakerphone can only provide a one-way communication path. KX-T2375MXW 13.4. Telephone Line Interface 13.4.1. Circuit operation On hook Q101 is open, Q101 is connected as to cut DC loop current and cut the voice signal. Off hook Q101 turns on thus providing an off-hook condition (active DC current flow through the circuit) and the following signal flow id for the DC loop current.

KX-T2375MXW 13.5. Tone Detect This circuit is used to sense the status of the line (busy tone or dial tone) during Auto Redial. Circuit operation D101 → Q101 → C201 → R201 → R205 → Pin 5 of IC201 → Pin 1 of IC201 → D202 → R208 → Q201. KX-T2375MXW 13.6. Inializing Circuit 13.6.1.

Function This circuit is used for to initialize the microcomputer when it incorporates batteries. Circuit operation When the batteries is inserted into the unit, then the voltage is shifted by D304 and power is supplied to the CPU.
