NOTE: If the DAX button above has been selected and PTT is initiated through CAT, audio will be used from the DAX source rather than the currently selected microphone input. If, however, a microphone PTT is depressed, the selected microphone will be used for input. This allows the operator to switch between a digital audio source and voice audio quickly.NOTE: With multiFLEX, the microphone PTT (and all other hardware PTT sources) will use the Local PTT Station to transmit (see section 21).
NOTE: When PC is the selected MIC input, transmit can only be initiated by the MOX button or VOX. The front or rear panel PTT will always override the PC MIC input and transmit using the last hard-wired MIC input that was used (MIC, BAL, LINE or ACC).
