For receiving, disable OT if equipped, unsquelch the radio, adjust the volume for a normal listening level, set the squelch control, and select the operating frequency by rotating the channel selector switch. If equipped with QT, inserting the microphone back into its hanger will activate KQT-8, allowing you to hear messages for your system only.
For transmitting, disable QT by pressing the monitor switch or removing the microphone from its hanger. Select the operating frequency, ensure the channel is not in use, and then key the transmitter by pressing and holding the microphone PTT switch. Speak at a normal voice level and keep transmissions brief. To receive a reply, release the microphone PTT switch. At the end of the conversation, enable QT by pressing the monitor switch and replacing the microphone into its hanger.
