Setting the radio to transmit through the ICRI
Set the audio level on each connected radios to mid-position.
NOTE: Some adjustment of volume position may be necessary to clarify radio sound, after mid-position is
established.
Set the radio to the desired channel.
Set the talk group switch
Up: Talk Group One
Down: Talk Group Two
Center: No Talk Group connection (mute)
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.
