The FCC Wants You to Know
WARNING! Uniden does not represent this unit to be waterproof. To reduce the risk of fire or electrical shock, do not expose this unit to rain or moisture.
Uniden® and Close Call® are registered trademarks of Uniden America Corporation. Other trademarks used throughout this manual are the property of their respective holders.
This scanner has been tested and found to comply with the limits for a scanning receiver, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This scanner generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this scanner does cause harmful interference to radio or television reception, which can be determined by turning the scanner on and off, you are encouraged to try to correct the interference by one or more of the following methods:
•Reorient or relocate the receiving antenna
•Increase the separation between the scanner and the receiver
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1) This device may not cause harmful interference, and 2) this device must
7
accept any interference received, including interference that may cause undesired operation.
Scanning Legally
Your scanner covers frequencies used by many different groups, including police and fire departments, ambulance services, government agencies, private companies, amateur radio services, military operations, pager services, and wireline (telephone and telegraph) service providers. It is legal to listen to almost every transmission your scanner can receive. However, there are some transmissions that you should never intentionally listen to. These include:
•Telephone conversations (cellular, cordless, or other private means of telephone signal transmission)
•Pager transmissions
•Any scrambled or encrypted transmissions
According to the Electronic Communications Privacy Act (ECPA), you are subject to fines and possible imprisonment for intentionally listening to, using, or divulging the contents of such a conversation unless you have the consent of a party to the conversation (unless such activity is otherwise illegal). This scanner has been designed to prevent the reception of cellular telephone transmissions and the decoding of scrambled transmissions. This is done to comply with the legal requirement that scanners be manufactured so they are not easy to modify to pick up these transmissions. Do not open your scanner’s case to make any modifications that could allow it to pick up transmissions that are illegal to monitor. Modifying or tampering with your scanner’s internal
8
components or using it in a way other than as described in this manual could invalidate your warranty and void your FCC authorization to operate it.
In some areas, mobile use of this scanner is unlawful or requires a permit. Check the laws in your area. It is also illegal in many areas (and a bad idea everywhere) to interfere with the duties of public safety officials by traveling to the scene of an incident without authorization.

BC75XLT Feature Highlights
Close Call® RF Capture Technology - you can set the scanner so it detects and provides information about nearby radio transmissions. See page 42 for more information on the
Close Call RF feature.
10
PC Programming - lets you program your scanner using your PC.
Custom Search - lets you program up to 10 custom search ranges and search any or all of those ranges.
Quick Search - allows you to enter a frequency and start searching up or down from that frequency.
Turbo Search - increases the search speed from 100 to 300 steps per second automatically for bands with 5 kHz steps.
Search Lockout - allows you to lock out up to 200 search frequencies (100 temporary and 100 permenant) in Custom,
Service, Close Call, or Quick Search modes.
Lock-Out Function - lets you set your scanner to skip over specified channels or frequencies when scanning or searching. You must manually unlock these channels.
Temporary Lock-Out Function - lets you set your scanner to skip over specified channels or frequencies when scanning or searching. This temporary lock-out releases when you manually unlock the channels or frequencies or when you power down the scanner.
Priority Channels - You can program one channel in each bank (10 channels total) as a priority channel. The scanner checks that channel every 2 seconds while it scans the bank so you do not miss transmissions on those channels. (Default=Priority Off)
Priority Scan - lets you set the Priority feature to check each channel every 2 seconds regardless of whether or not the scanner is receiving transmissions.
11
Priority Scan with Do Not Disturb - lets you set the Priority feature to check each channel every 2 seconds as long as the scanner is not receiving transmissions.
Duplicate Channel Alert - lets you know when you have entered a frequency that is already registered on another channel.
Channel Storage Banks - the scanner has 10 banks. You can store up to 30 frequencies into each bank (for a total of 300 frequencies), so you can more easily identify calls.
Two-Second Scan Delay - delays scanning for about 2 seconds before moving to another channel so you can hear more replies that are made on the same channel.
Do Not Disturb prevents the scanner from interrupting transmissions during receiving.
Ten Service Bands - frequencies are preset in separate Weather, Police, Fire/Emergency, Marine, Racing, Civil Air, HAM Radio, Railroad, CB Radio, and Other (Other = FRS/ GMRS/MURS) bands to make it easy to locate specific types of calls.

Scanning basics
This section provides a background on how scanning works. You don’t really need to know all of this to use your scanner, but some background knowledge will help you get the most from your BC75XLT.
What is Scanning?
Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. Your BC75XLT scans programmed channels until it finds an active frequency, then stops on that frequency and remains on that channel as long as the transmission continues. When the transmission ends, the scanning cycle resumes until it receives another transmission on a programmed channel.
What is Searching?
The BC75XLT searches for active frequencies. This is different from scanning because you are searching for frequencies that have not been programmed into the scanner. When you select frequency bands to search, the scanner searches for any active frequency within the lower and upper limits you specify for that band. When the scanner finds an
active frequency, it stops on that frequency as long as the transmission lasts. If you think the frequency is interesting, you can program it into one of the bands. If not, you can continue to search.
17
Conventional Scanning
Conventional scanning is a relatively simple concept. Each group of users in a conventional system is assigned a single frequency (for simplex systems) or two frequencies (for repeater systems). Any time one of them transmits, their transmission always goes out on the same frequency. Up until the late 1980’s this was the primary way that radio systems operated.
Even today, there are many 2-way radio users who operate using a conventional system:
•Aircraft
•Amateur radio
•FRS/GMRS users
•Broadcast AM/FM/TV stations
•Many business radio users
When you want to store a conventional system, all you need to know are the frequencies they operate on. When you
are scanning a conventional system, the scanner stops very briefly on each channel to see if there is activity. If there isn’t, the scanner quickly moves to the next channel. If there is, then the scanner pauses on the transmission until it is over.
Simplex Operation
Simplex systems use a single frequency for both transmit and receive. Most radios using this type of operation
are limited to line-of-sight operation. This type of radio is frequently used at construction job sites and with
inexpensive consumer radios such as GMRS/FRS radios. The range is typically 1-8 miles, depending upon the terrain and many other factors.
