Engagement status
The radio is engaged when an active DSC-initiated communication is ongoing,
or communication is active on non-DSC initiated MF/HF operation:
•
A new channel is selected
•
PTT is pressed
•
Voice signal is received (if squelch is enabled)
The engagement state is used to prohibit incoming DSC calls from taking over
control of the transmitter channel, disrupting ongoing communication.
When the radio is engaged in communication not initiated by DSC, this is
indicated with the symbol
in the display. Engagement will automatically
time-out on inactivity, after an inactivity time specified in
DSC setup
on
