KX-TS3MXB / KX-TS3MXF / KX-TS3MXP / KX-TS3MXR / KX-TS3MXW 12 CIRCUIT OPERATIONS Note: The circuit diagram may be modified at any time with the development of new technology. 12.1. Telephone Line Interface and Pulse Dial Circuit When the hook switch SW1 is ON (off-hook), the circuit is closed, and current is supplied to the base of Q2 via the diode bridge D1 and Q2 is On →...
KX-TS3MXB / KX-TS3MXF / KX-TS3MXP / KX-TS3MXR / KX-TS3MXW 12.3. Ringer Circuit Circuit Operation: The bell signal passes through C1 (R1) → supplying power to pin 1 of IC2. The ring signal is output from Pin 5 of IC2, and its volume is adjusted in 3 steps (H-L-OFF) by SW3 then impressed on the ceramic sound generator, and so is generated.
