briefly press the SCAN key to cancel the scan function.

memory. It can be removed by holding the SCAN key

To Scan in Open Scan Mode:
If a busy channel is found, scanning will pause on that
channel to allow the signal to be heard and will remain
there for as long as the channel remains busy.
• To skip over a busy channel, briefly press the SCAN
key twice.
• To talk on a busy channel while in Scan mode simply
press the PTT (Push-To-Talk) button on the microphone.
When you have finished transmitting and the channel
