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 o, 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 receiverThis 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
8accept any interference received, including interference that may cause undesired operation.SCANNING LEGALLYYour scanner covers frequencies used by many dierent groups, including police and re 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 nes 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 modications that could allow it to pick up transmissions that are illegal to monitor. Modifying or tampering with your scanner’s internal
9components 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 ocials by traveling to the scene of an incident without authorization.

17SCANNING BASICSThis 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 nds 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 dierent 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 nds 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.
18Conventional ScanningConventional 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 briey 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 OperationSimplex 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.
19Repeater OperationRepeater systems use two frequencies: one transmits from the radio to a central repeater; the other transmits from the repeater to other radios in the system. With a repeater-based system, the repeater is located on top of a tall building or on a radio tower that provides great visibility to the area of operation. When a user transmits (on an input frequency), the signal is picked up by the repeater and retransmitted (on an output frequency). The user’s radios always listen for activity on the output frequency and transmit on the input frequency. Since the repeater is located very high, there is a very large line of sight. Typical repeater systems provide coverage out to about a 25-mile radius from the repeater location. WHAT ARE BANKS?Channel Storage BanksTo make it easier to identify and select the channels you want to listen to, the 300 channels are divided into 10 channel storage banks containing 30 channels each. You could use each channel storage bank to group frequencies by department, location, area of interest, or any other way you prefer. You can listen to any or all of the banks by using the number keys to turn them on or o.Service Search BandsThe scanner is preprogrammed with many of the frequencies allocated to Weather, Police, Fire/Emergency, Marine, Racing, Civil Air, HAM Radio, Railroad, CB radio, and Other (Other = FRS/GMRS/MURS). Use the 10 bands allocated for
20these service searches just like the channel storage banks, searching the frequencies using Service Search mode (see page 37).Custom Search RangesCustom Search mode lets you program the upper and lower limits of search ranges. You can then search these 10 custom search ranges starting from the lowest frequency to the highest frequency in the search range you entered. You can turn o ranges you don’t want to search just like turning o (disabling) channel storage banks in Scan mode.Custom search ranges use the same LCD numbers on the display as the 10 channel storage banks (see page 32).WHERE TO LEARN MOREBy itself, this manual really only provides part of what you need to know to have fun scanning – how to program and use the scanner.

22SETTING UP THE SCANNERConnect the Antenna1. Align the slots around the antenna’s connector with the tabs on the scanner’s BNC connector. 2. Slide the antenna’s connector down over the scanner’s connector. 3. Rotate the antenna connector’s outer ring clockwise until it locks into place.The scanner’s BNC connector makes it easy to connect a variety of optional antennas, including an external mobile antenna or outdoor base station antenna.Note: Always use 50-ohm, RG-58, or RG-8, coaxial cable to connect an outdoor antenna. If the antenna is over 50 feet from the scanner, use RG-8 low-loss dielectric coaxial cable. If it is less than 50 feet, use RG-58. You can get a BNC adapter at local electronics stores.
23Connect an Optional Earphone/HeadphoneFor private listening, you can plug a 1/8-inch (3.5 mm) mini-plug earphone or stereo headphones (not supplied) into the headphone jack on top of your scanner. This automatically disconnects the internal speaker.Connecting an Optional Extension SpeakerIn a noisy area, an optional extension speaker, positioned in the right place, might provide more comfortable listening. Plug the speaker cable’s 1/8-inch (3.5-mm) mini-plug into your scanner’s jack. If your speaker’s cable ends in a mono plug, use a mono-to-stereo adapter to prevent shorting the audio amplier and reducing volume.WARNING! If you connect an external speaker to the scanner’s headphone jack, never connect the audio output line to a power supply and ground. This might damage the scanner.Adjusting the Belt ClipThe factory-attached belt clip makes it easier to carry the scanner. Use a Phillips screwdriver to adjust (loosen) the mounting screws or remove the belt clip completely. POWERING THE SCANNERUse the provided USB cable to connect your scanner to your computer to charge the Ni-MH batteries (not included) on initial installation and to recharge them.

If the scanner cannot immediately
27determine if the batteries are good and can be charged, it checks them and displays the battery icon. If the scanner judges the batteries are good, the scanner starts charging and the battery icon disappears. If it cannot regard the batteries as good in 60 seconds, the scanner stops checking and the battery icon blinks. Low Battery AlertThe Low Battery Alert tone sounds every 15 seconds and the battery icon ashes when the battery voltage is low. If it drops below the threshold, the scanner automatically shuts o until the battery is recharged.TURN ON THE SCANNER Turn on the scanner after it has been completely charged (Ni-MH batteries) or alkaline batteries have been installed.Note: Make sure the antenna is connected before you turn on the scanner.1. You can select the band plan (USA or Canada) when you turn on the scanner (default = USA). Press and hold the key for 2-3 seconds to turn on the scanner and then press and hold 1 for USA or 2 for Canada. The band plan will remain until you change it again.2. If this is the rst time you have turned on the scanner, All LocOut displays. This means that no frequencies have been saved into channels. Press Srch to begin searching.
28Adjust SquelchThe scanner recognizes signals as transmissions if they exceed a signal strength threshold. Adjusting the squelch sets this threshold level. Increasing squelch requires a signal to be stronger to be seen as a transmission. If you set the squelch too high, you will risk not receiving transmissions that are lower than that threshold. Reducing the squelch allows weaker signals to be accepted. However, if you lower the squelch too much, you will hear white noise all the time.1. Press Func and the press down and release the scroll control knob. SqL and a number display.2. Turn the knob until the interference is gone. Press the scroll control knob again to set the level and return to the previous function.Adjusting for InterferenceThere are several options to adjust your scanner to minimize interference. Try:• Moving the scanner or its antenna away from the source. • Using an optional external antenna designed for multi-band coverage. (You can purchase this type of antenna at a local electronics store). If the optional antenna has no cable, use 50-70 ohm coaxial cable for lead-in. An adapter might be necessary for the optional antennas. • Moving the scanner from high-moisture environments such as the kitchen or bathroom. • Moving the scanner from direct sunlight or near heating elements or vents.

Press Srch to start searching your custom search range or turn the scroll control knob to a dierent search range and enter another frequency.Service SearchYou can search for Weather, Police, Fire/Emergency, Marine, Racing, Civil Air, HAM Radio, Railroad, CB radio, and Other (Other = FRS/GMRS/MURS) transmissions without knowing the specic frequencies used in your area. The scanner is preprogrammed with all the frequencies allocated to these services. To use this feature, press Func + Svc. SRCH appears and the scanner starts searching from the weather service bands. To select a dierent service search, repeatedly press Svc as long as you are still in Function mode. If you are not in Function mode, press Func to return and then press Svc.Services are scanned in the following order: Weather, Police, Fire/Emergency, Marine, Racing, Civil Air, HAM Radio, Railroad, CB radio, and Other (Other = FRS/GMRS/MURS). When the scanner stops on a transmission, press Hold to stop searching and listen to the transmission. Hold displays. In this mode, you can also turn the scroll control knob to step through the frequencies.To release the hold and continue searching, press Hold again.Note: Because there are many dierent frequencies allocated to re and police departments, it can take several minutes to search all the service frequencies.
38STORING FREQUENCIES To store frequencies in the rst available channel:1. Press Hold.2. Enter the frequency and press Hold and Func + Pgm.3. The scanner alternates between the frequency you are stopped on and the rst available channel number with no frequency stored. Press E.4. The scanner is now on that frequency, on Hold with the Delay function automatically turned on (see page 47). Press Srch or Scan again to continue.Note: Refer to www.radioreference.com for a list of frequencies in your area.You can also store frequencies directly into a specic channel in a specic channel bank.1. From Search or Scan modes, press Hold.2. Press Func + Pgm. The scanner displays the next available channel number and alternates between O and the frequency you’re holding on. 3. Press Func and turn the scroll control knob to change channel banks if desired; press Func again to select that channel bank. 4. Turn the scroll control knob to change channels within that bank. 5. Press E to store the frequency in the displayed channel/channel bank.6. The scanner is now on that frequency, on Hold with the Delay function automatically turned on (see page 47).
39If you entered a frequency that has already been entered elsewhere, the scanner sounds an error tone and displays the channel that was duplicated. If you entered the frequency by mistake, press .Clr twice to clear the frequency and enter a dierent one. To enter the frequency anyway, press E to accept.Erasing a Stored Frequency1. Find the frequency you want to erase. Press Hold.2. Press Func + Pgm.3. Press 0 and then press E.4. The displayed frequency changes to all 0s.SCANNINGWhen you store frequencies into channels, those channels are grouped into banks. Each bank contains 30 channels. You can store service channels and non-service channels in the same bank. For example, you can store a city’s re, police, marine, etc, together with utilities and other businesses. There is no frequency range restriction per bank.While you are scanning frequencies stored in the banks, the word SCAN scrolls across the display. When it nds a transmission, that frequency displays.Enabling/Disabling Channel BanksYou can enable and disable each channel bank. When you disable a bank, the scanner does not scan any of the 30 channels in that bank.In Scan modes, press the number key that corresponds to the bank you want to disable or enable. That bank number
40displays at (or disappears from) the top of the screen, showing the currently enabled banks.The scanner scans all the channels within the displayed banks that are not locked out. The bank number ashes when the scanner scans a channel that belongs to that bank.You can manually select any channel within a bank, even if that bank is disabled. You cannot, however, disable all banks. One bank must always be enabled.Scan the Stored ChannelsPress Scan. The scanner scans through all non-locked out channels in enabled banks. (See page 44 for more information on locking out channels.) When the scanner nds a transmission, it stops on it. When the transmission ends, the scanner resumes scanning.Notes:• If you have not stored frequencies into any channels, the scanner does not scan.• If the scanner picks up unwanted partial or very weak transmissions, press Func and press the scroll control knob. SqL displays. Turn the knob clockwise to decrease the scanner’s sensitivity to these signals. To listen to a weak or distant station, turn the knob counterclockwise.• Adjust squelch until the audio mutes.Manually Select a ChannelYou can continuously monitor a single channel without scanning. This is useful if you hear an emergency broadcast on a channel and do not want to miss any details - even though there might be periods of silence - or if you want to monitor a specic channel.
41To manually select a channel when in Scan mode, press Hold, enter the channel number, and press Hold again.The scanner moves to the frequency stored in that channel. During scanning, if the radio stops at a channel you want to listen to, press Hold once. (Rotate the scroll control knob to step through stored channels.) Press Hold again or Scan to resume automatic scanning.
42SPECIAL FEATURESCLOSE CALL® RF CAPTUREYour scanner’s Close Call feature lets you set the scanner to detect then display the frequency of a nearby strong radio transmission such as mobile and handheld two-way radios in areas with no other strong transmission sources. However, if you are in an area with many transmission sources (such as pager radio transmitters, multi-use radio towers, trac control devices, etc.), Close Call mode might not nd the transmission you are searching for, or it might nd a transmission other than the one you are searching for.Close Call mode works well for nding frequencies at venues such as malls and sporting events. You can set the scanner so that Close Call detection works “in the background” while you are scanning other frequencies. You can turn o the Close Call feature and scan normally as well as turn o the scanning function and look for Close Call transmissions only.Close Call Operation Mode1. Press Func and hold until the following screen displays: B: 1 2 3 4D LY
432. For the Close Call mode, frequencies are divided into 4 Close Call bands. Turn these bands on and o by pressing 1 - 4 as indicated:Band Range (MHz) To turn a Close Call band on/o, press...Low HighVHF Low 25.00000 54.00000 1AIR 108.00000 136.99166 2VHF High 137.00000 174.00000 3UHF 406.00000 512.00000 4You can set the scanner so it alerts you when the Close Call feature detects a frequency. Program alert tones through your PC (see page 49).Notes: • Close Call RF capture cannot detect frequencies outside the scanner’s normal operating range.• Close Call mode works better with some types of transmissions than others. It might not correctly display frequency information for transmitters using a highly directive antenna (such as an amateur radio beam antenna), if there are many transmitters operating at the same time in the same area, or if the transmitter is a broadcast television station.Using Close Call Mode Close Call mode has three operation modes:
44• Close Call DND. Close Call Do Not Disturb only checks for close calls if it is not stopped on a transmission. The icon displays.• Close Call Priority. The scanner checks for close calls regardless of whether it is stopped on a transmission. The icon displays.• Close Call O. The scanner does not check for close calls. No icon displays.Pressing Fnc + cycles through the Close Call functions in this order: Close Call O/Close Call DND/ Close Call Priority.To turn on Close Call mode, press Func + once except in WX Search, Band Select, or Program mode. Notes: • Set the squelch tight (where only strong signals are received) while using the Close Call feature.• To continue scanning normally while the Close Call feature is working, simply press Scan.When the scanner nds a frequency, Found displays; it does not display the frequency. Press any key to conrm the displayed frequency. Press Scan to resume scanning. Every 2 seconds, the scanner checks for frequencies in the Close Call band you specied (see page 43).LOCKING OUT CHANNELS AND FREQUENCIESYou can skip any channel or up to 200 specied frequencies during Search mode (100 permanent and 100 temporary). This lets you avoid unwanted frequencies (Search/Close Call modes), channels that have a continuous transmission (such as a weather channel), or have static and interference.
45Temporary Lock OutTo temporarily lock out a channel in Scan mode or a frequency in Search and Close Call modes, manually select the channel or frequency (see page 40) and then press L/O. TL/O appears. You have TEMPORARILY locked out the channel/frequency. Permanent Lock OutTo permenantly lock out a frequency or channel, press L/O twice while on that frequency. L/O displays. Note: You can still manually select locked-out channels.UnlockUnlock Temporary Lock Out1. Locate the temporarily locked out channel; press Hold.2. Press L/O until the locked out status no longer displays. 3. Press Hold again to return to Scan or Search modes.You can also turn the scanner o and back on. It will unlock all channels that have been temporarily locked outUnlock Permenant Lock OutTo unlock a permanently locked-out frequency/channel:1. Manually enter the frequency/channel then press Hold. The frequency and lockout status display. 2. Press L/O until the locked out status no longer displays. 3. Press Hold again to return to Scan or Search modes.To unlock all registered channels in enabled banks, press Hold to stop scanning, then press and hold L/O until the
46scanner beeps twice and CLEAr displays. Press E to unlock all. Notes: • You cannot lock out frequencies during WX service search.• Locked out frequencies are shared between Service Search, Custom Search, Quick Search, and Close Call modes. If locked out frequencies are set in a specic mode, those frequencies are also skipped in other Search (except WX Service Search) and Close Call modes.• If you selected all frequencies in a search band to be skipped, the scanner beeps 3 times and does not search.• You can skip 100 frequencies for Temporary Lockout and 100 frequencies for Permenant Lockout (200 locked out frequencies total). After locking out 200 frequencies, the next time you try to select a frequency to skip the scanner displays Full and will not lock out that frequency.• If you want to nd your locked-out frequencies, press Hold and then turn the scroll control knob to cycle through the frequencies. L/O or T/LO displays on the locked out frequencies.PRIORITYThe Priority feature lets you scan through the channels and still not miss important or interesting calls on specic channels. There are three Priority options available in Scan or Scan Hold mode:• Priority O (no display) : The scanner does not check for priority channels.• Priority DND ( PRI displays) : In Priority Do Not Disturb (DND), the scanner checks Priority channels
47every 2 seconds only when it is not receiving transmissions.• Priority Scan (PRI displays) : The scanner checks Priority channels every 2 seconds regardless of whether or not it is receiving a transmission.You can designate one channel in each bank as a priority channel (10 total). The rst channel in each bank is the default Priority channel.Follow these steps to select a dierent channel in a bank as the priority channel.1. Manually select the channel you want for the Priority channel.2. Press Func + Pgm, then press Func + Pri. P appears to the left of the selected channel number.3. Repeat Steps 1 and 2 for other channels for each bank you want to program as a priority channel.From Scan Hold mode, press Func + Pri to cycle through the Priority options.DELAYSometimes a user might pause before replying to a transmission. To avoid missing a reply on a specic channel, you can program a 2-second delay into channels or searches. The scanner continues to monitor the channel frequency for an additional 2 seconds after the transmission stops before resuming scanning or searching. Mode Delay SpecicationScan Each channel can be set individually.
