The phototransistor receives the transmitted signal and provides it to pin 2 of IC2 for amplification. The amplified output from IC2 pin 6 is provided to the base of the relay driver transistor (T2) through the non-polarized capacitor C5, diode D1 and resistor R8. The variable resistor VR1 is used to match the transmitted and received signals.
