Introduction
TheBC 245XLTis a state-of-the-art radio with
TrunkTracking™and automatic scanning capabilities. It
can store frequencies such as police, fire/emergency,
marine, railroad, air, amateur, and other communications
into 10 banks of 30 channels each.
With the new SmartScanner™ feature, you can also
automatically program your scanner by downloading
directly from our Uniden/Bearcat national frequency
database via a PC or external modem.
Use your new scanner to monitor:
nUHF High Band UHF 800/900 MHz...

Important Notice
nThis scanning radio has been manufactured so
that it will not tune radio frequencies assigned by
the FCC for cellular telephone usage. The
Electronic Communications Privacy Act of 1986, as
amended, makes it a federal crime to intentionally
intercept cellular or cordless telephone
transmissions or to market this radio when altered
to receive them.
nThe installation, possession, or use of this
scanning radio in a motor vehicle may be
prohibited, regulated, or require a permit in certain...

Terminology
What is Scanning?
Unlike standard AM or FM radio stations, most two-way
communications do not transmit continuously. The
BC 245XLTscans the channels you program until it finds
an active frequency.
Scanning stops on an active frequency and remains on
that channel as long as the transmission continues. When
the transmission ends, the scanning cycle resumes until
another transmission is received.
What is Searching?
TheBC 245XLTcan search each of its 12 bands to find
active frequencies. This is...

In a trunked radio system, which contains up to 28 different
frequencies, radio users are divided into groups, often
called talk groups, and these talk groups are assigned
specific IDs. When someone in a talk group uses their
radio, a brief burst of data is broadcast before each
transmission. The trunking system computer uses this data
to temporarily assign each radio in a talk group to an
available frequency. If the group using a frequency stops
broadcasting or pauses between replies for a few seconds,...
