When you find a frequency, you can store it into a
programmable memory location called a channel, which is
grouped with other channels in a channel-storage bank.
You can then scan the channel-storage banks to see if there
is activity on the frequencies stored there. Each time the
scanner finds an active frequency, it stays on that channel
until the transmission ends.
