Audio signals from the interphone amplifier are applied through low-pass filter FL8701 whose main

function is to attenuate signals above 3000 Hz. The 150 Hz signal generated in squelch amplifier

A5200 is applied to the resistor network and combined with the filtered audio.

The 150 Hz tone signal from squelch amplifier A5200 is always generated in transmit mode. The

combined signals are applied to module A8100.
