Your radio chirps for about 10 seconds while it

radio receives the channel change signal, it chirps
once, then changes to the new channel.
To ensure all radios make it to the new channel, we
recommend you:
Make sure you are in an open environment,
where the radio will get the best range.
Optimize range during the channel change
signal by raising the radio over your head to give
the best possible height.
Do a "roll call" on the new channel after the
move to be sure no one was left behind. If you
missed someone, return to the previous channel
and issue the signal again.
