in kHz or MHz). To fi nd active frequencies, use the search
function or purchase a frequency reference.
In addition to searching a selected frequency range, you can
also search your scanner’s service banks. A

is a preset groups of frequencies categorized by the type
of services that
use those frequencies. Your scanner comes
preprogrammed with all the frequencies allocated to the
weather, marine, aircraft, rail road, CB, news, and police/fi re/

When you search and fi nd a desired frequency, you can
store it into a
PROGRAMMABLE MEMORY LOCATION called
a CHANNEL . Channels are grouped into channel-storage
