When the radio is in Unit-To-Unit Mode, all
scanning functions will be disabled. The radio

Transmit (RTX) channel only. Depending on
programming, the RTX channel can be the
main channel, a held scan or priority channel if
Talkback Scan is enabled, or the Priority 1
channel if TX on PR1 is enabled. To alert the
user that the radio is in Unit-To-Unit Mode, a
beep will periodically sound until the unit is
returned to normal Operating Mode.
