The transceiver will scan through the whole transceiver
channels. If your transceiver detects a valid signal the scan will
pause for the period that has been set by the menu mode
setting (continuously receiving or 1-99 seconds for scan
receive time and immediate response or 1-99 seconds for scan
delay time).
If you press the PTT button when your transceiver detects a
signal, the radio will transmit on the same channel. Scanning
will resume after the scan receive time and/or the scan delay
time. Use the channel selector or quick up/quick down selector
to resume scanning immediately.
