: The COM 7, COM 8, COM 9 and AUX transceivers may be configured as duplex, and used with a
cellphone or sat-phone. Check your configuration with the installing agency.
If the unit has been configured for cellphone or sat-phone use and one of the configured COMs has been selected for
transmit, momentarily activating the TX PTT will keep the transceiver transmitting. A second momentary activation of
the TX PTT, or moving the Transmit Selector away from that transceiver, will stop the transmission.

VOX Operation
USER 1 MIC audio is routed to the ICS when the MIC audio level exceeds the VOX threshold.
USER 1 MIC audio is disconnected from the ICS when the MIC audio level falls below the VOX threshold for 0.5 to 2
seconds.

ICS Operation
ICS audio is the sum of all the MIC audio from users with ICS KEY active or with MIC audio level exceeding the VOX
Threshold level.
