Operation
Channel information always available in the display
For some functions and for the setup pages,
the channel and radiotelephony information
has moved to the bottom section of the
display. You can change frequencies whenever
the frequencies are displayed.
If PTT is pressed the radio transmits on the
displayed frequency on which the radio is
tuned into for communication. If a signal is
received, it is received on the displayed
frequency.
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 or,
• 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
page 40.
To terminate the engagement immediately press the soft key QUIT.
