TRANSMIT INDICATIONS

During COM transmission, a white 'TX' appears by the active COM frequency replacing the Frequency

Transfer Arrow. On the Audio Panel, when the active COM is transmitting, the active transceiver COM MIC

Key Annunciator ﬂashes approximately once per second.

STUCK MICROPHONE

If the push-to-talk (PTT) Key becomes stuck, the COM transmitter stops transmitting after 35 seconds of

continuous operation. An alert appears on the PFD to advise the crew of a stuck microphone.

The COM1 MIC or COM2 MIC Key Annunciator on the Audio Panel continues to ﬂash as long as the PTT

Key remains stuck.
