Important Notice This 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 t[...]

Terminology What is Scanning? Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. The BC 245XLT scans 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 sca[...]

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 temporari[...]

Feature Highlights Trunk Tracking – Follow UHF High Band UHF 800/900 MHz trunked public safety and public service systems just as if conventional two-way communications were used. Multi-Track – Track more than one trunking system at a time and scan conventional and trunked systems at the same time. 300 Channels – Program one frequency into ea[...]

Battery Save – In manual mode, your scanner automatically reduces its power requirements to extend the battery’s charge. Attenuator – Reduces the signal strength. SmartScanner™ – Automatically program your BC 245XLT with all the frequencies and trunking talk groups for your local area by accessing our national database with your PC or jus[...]
