User manual UNIDEN BC 120XLT

[. . . ] Please read this Operating Guide thoroughly before attempting to operate the unit. What are Highway Patrol Warning Alerts? Most highway patrol vehicles on the road today are equipped with a secondary radio system known as a "mobile extender" or "vehicular repeater. " Whenever the dispatcher transmits to any vehicle in the district, every "mobile extender" in every car within the district is activated. Using a constant PRIORITY check of specific frequencies in each state, the BCT7 recognizes and alerts you to transmissions from "mobile extender" radios as well as from car-to-car, aircraft-to-car and other special-purpose frequencies. You receive an audible (beep tone) and visual (flash of warning light) alert whenever you are within an approximate three mile radius of many Highway Patrol/State Police units. 2 What is Scanning? Unlike standard AM or FM radio stations, most two-way communications (listed on the page 5) do not transmit continuously. The BCT7 scans programmed channels at the rate of nearly 100 channels per second until it finds an active frequency. [. . . ] In Scan Mode When the scanner stops on a frequency you don't want to hear, press L. Á Scanning resumes immediately because that frequency is no longer in the scanning sequence. HIGHWAY POLICE DOT WX PRIVATE FIRE NEWS AIR 15 In Hold Mode Press L. Á LOCKOUT appears on the display. Scanning doesn't resume until you press H. Lockout Tips After you have locked out the 50th preprogrammed frequency (or 100th user programmed frequency), you may lock out a new frequency. However, the first frequency you locked out becomes unlocked to make room for the new frequency. However, if you do, pressing that bank key will emit an error tone and the scanner will not scan. If you lock out a preprogrammed frequency in one bank, and that frequency is programmed into another bank, the frequency is locked out of both banks. 16 Restore a Locked Out Frequency 1. Press H to resume scanning. Restore All Locked-Out Frequencies Press and hold L for two seconds. Á You'll hear two beeps when all frequencies are restored. OR In the Alert Monitor Frequency Banks, press S to change the state code. Lockout is cleared as soon as scanning starts. 17 Search You can use the SEARCH feature to find active frequencies in your area. Many frequencies have already have been pre-programmed into one of the SCAN MODES (Highway, Police, DOT, etc. ). You can search for any frequencies between 29. 000 and 956. 000 MHz, as well as CB channels 1 through 40, as long as they are within the 12 Bands covered by the BCT7. See the table on page 5, or the Specifications at the back of this Guide. Two seconds later, the BCT7 begins searching that band. or > to change Á Press <(up or down) of thethe direction frequency search. OR Press B repeatedly to select another band. During Search, press L to lockout undesired frequencies that the scanner stops on. Note: AIR appears when searching the Aircraft Band. 18 CB Channel Search The 40 Citizen's Band (CB) channels comprise one of the 12 search bands available in the BCT7. Connect the BCT7 power cord directly to the fuse block or battery of your car. - OR Plug one end of the cigarette lighter power cord into your vehicle's cigarette lighter. Connect the power cord to the jack marked "DC 13. 8V" on the back of the radio. Attach the external antenna connector to the jack marked "ANT. " Note: The power cord provided with your BCT7 contains a 1-amp fuse. Uniden recommends using an external antenna designed specifically for scanning radios. Do not use the telescoping antenna in a mobile installation. 26 Base Installation In addition to mobile installation, you can operate the BCT7 as a base unit with the included AC Adapter and Telescoping Antenna. Plug the telescoping antenna into the antenna jack on the rear of the unit. Operation of the scanner is the same as for mobile use. 27 Tips & Techniques Leave the Band Search set for CB (CB follows 806-956 MHz and precedes 29-30 MHz). This way, whenever you wish to monitor CB radio traffic, you simply press the BAND button once. Another suggestion for highway driving would be to program CB channel 19 into one of the available HIGHWAY programmable channels in the BCT7. Truckers and other motorists also use other CB frequencies (such as 11 at times) for highway communications, but 19 is the most common channel. [. . . ] If you're monitoring user-programmed frequencies, switch to one of the preprogrammed frequency banks. Sometimes, in a heavily congested area with a lot of radio transmitters (an urban area or an area where TV/ radio towers are located), this always occurs. Try turning your squelch down or locking out the offending frequencies. If you still cannot get satisfactory results, call the Uniden Customer Service Center at 1-800-297-1023, 8 a. m.
