Because the ICRI is connected to the radio via the speaker jack, the audio path on the attached radio is
disrupted. You will be unable to hear or speak through that radio. If you can hear or talk through the radio,
the cable may not be properly attached to your radio.
The LED directly above the radio will light as audio is transmitted from the radio through the ICRI.
