About the COM1 MIC button


VHF Comm - Icom A200 (Upper unit)

    Pressing the COM1 MIC button selects the Com 1 transmitter and receiver.    

No other selection is needed to use just Com1

    When COM1 MIC is selected, pressing COM2 simultaneously monitors Comms 1 & 2 but transmission is only on Com 1    
    The COM1 MIC indicator light blinks while the Com1 transmitter is keyed on    
    Include these indicators in your panel scan to detect inadvertent transmitter activation
