INTRODUCTION Thank you for purchasing a Uniden UBC75XLT handheld scanner. The scanner is versatile, compact, and easy to use. In addition to its standard scanning features, your scanner also includes Close Call® RF capture technology designed to help you detect and identify strong local radio signals in your area. You can program up to 300 frequencies into the scanner’s memory. The scanner lets you scan transmissions and is preprogrammed with service bands for your convenience.
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.
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.
Three Power Options - Use the supplied USB cable to charge the UBC75XLT through your computer or other USB charging port. You can also power the scanner using two AA rechargeable Ni-MH batteries or optional alkaline batteries (not included). Key Confirmation Tones - the scanner sounds a tone when you perform an operation correctly, and an error tone if you make an error. Battery Low Alert - warns you when battery power gets ) and a battery low low.
FREQUENCY RANGE These tables list the frequency ranges, default frequency step, default mode (AM or FM), and type of transmissions you can hear for each range for Band Plan 1 or 2. Select the band plan (Band Plan 1 or 2) when you turn on the key scanner (default = Band Plan 1). Press and hold the for 2-3 seconds to turn on the scanner while pressing and holding 1 for Band Plan 1 or 2 for Band Plan 2. The band plan will remain until you change it again.

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 UBC75XLT. WHAT IS SCANNING? Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. Your UBC75XLT 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.
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.
Repeater Operation Repeater 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).
searches just like the channel storage banks, searching the frequencies using Service Search mode (see page 33). Custom Search Ranges Custom 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 off ranges you don’t want to search just like turning off (disabling) channel storage banks in Scan mode.
SETUP WHAT’S IN THE BOX? UBC75XLT Scanner Antenna Belt Clip (attached) Not shown: • Rechargeable Ni-MH Batteries • USB cable • Strap • Owner’s Manual UBC75XLT_UB372BV_20130401.
SETTING UP THE SCANNER Connect the Antenna 1. 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.
Connect an Optional Earphone/Headphone For private listening, you can plug a 1/8-inch (3.5 mm) miniplug 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 Speaker In a noisy area, an optional extension speaker, positioned in the right place, might provide more comfortable listening. Plug the speaker cable’s 3.5-mm mini-plug into your scanner’s jack.
Inside the battery compartment is a switch; set the unit to either ALK or Ni-MH to match the type of battery you’re using. WARNING! Non-rechargeable batteries can get hot or burst if you try to charge them. CAUTIONS: • When flashes in the display and the scanner beeps every 15 seconds, recharge or replace the batteries. • Use only fresh batteries of the required size and recommended type. • Always remove old or weak batteries. Batteries can leak chemicals that destroy electronic circuits.
1. Make sure the power is turned off. 2. Slide the battery compartment cover off. 3. Use a pointed object such as a ballpoint pen to set the battery selection switch inside the compartment to Ni-MH. 4. Install two batteries in the compartment as indicated by the polarity symbols (+ and -) marked inside the battery compartment. 5. Replace the battery compartment cover. Note: To prevent damage to Ni-MH batteries, never charge them in an area where the temperature is above 45°C or below 4°C.
3. Connect the other end of the USB cable to the computer’s USB port or to an AC or DC adapter that provides USB charging power. Note: If you connect to a computer’s USB port, the PC will prompt you for the drivers for your scanner. USB drivers and optional programming software are available for download from http://www.butel.nl/ubc75xlt . These will also be available on the CD’s with ARC75 Software. 4. The scanner displays CHArg and the low battery icon while it charges the batteries.
If the batteries are good, the scanner charges the batteries. and it operates normally. If the scanner cannot immediately determine 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.
Adjust Squelch The 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.

It also has 10 preset service bands that display in two rows across the bottom of the screen when you press Func + Svc. Note: Service Search is discussed on page 33. When you press Srch, the UBC75XLT begins searching the search ranges until it finds activity. The search range number flashes and it remains on that frequency until activity ends.
to the nearest valid frequency. For example, if you enter 151.473 (MHz), your scanner accepts it as 151.475. However, if you enter a frequency that is out of range, the scanner sounds an error tone and Error appears. Enter another frequency. 3. Press Srch. The scanner searches, starting from the frequency you just entered. (Turn the scroll control knob to change the search direction.) The scanner also automatically turns on the Delay function; DLY displays.
5. Press Srch to start searching your custom search range or turn the scroll control knob to a different search range and enter another frequency. Service Search You can search for Emergency, Freenet, PMR, Marine, Air, CB radio, and HAM radio transmissions without knowing the specific frequencies used in your area. The scanner is preprogrammed with all the frequencies allocated to these services. To use this feature, press Func + Svc.
STORING FREQUENCIES Storing Found Search Frequencies To store found frequencies in the first available channel: 1. When the scanner finds a transmission with Search mode, press Hold to pause scanning. HOLD appears. 2. Press Func + Pgm. The scanner alternates between the frequency you are stopped on and the first available channel number with no frequency stored. 3. Press E. The scanner is now on that frequency, on Hold with the Delay function automatically turned on (see page 44). 4.
• If 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 different one. To enter the frequency anyway, press E to accept. Programming Channels To store desired frequencies in the selected channel: 1. From Scan mode, press Func + Pgm. PGM appears. 2. Turn the scroll control knob to choose the channel. 3.
3. Press 0 and then press E. 4. The displayed frequency changes to all 0s. SCANNING When 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 emergency, freenet, marine, etc, together with utilities and other businesses. There is no frequency range restriction per bank.
Scan the Stored Channels Press Scan. The scanner scans through all non-locked out channels in enabled banks. (See page 41 for more information on locking out channels.) When the scanner finds 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.
SPECIAL FEATURES CLOSE CALL® RF CAPTURE Your 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, traffic control devices, etc.
2. For the Close Call mode, frequencies are divided into 4 Close Call bands. Turn these bands on and off by pressing 1 - 4 as indicated: Band Plan 1 Range (MHz) Band Low High To turn a Close Call band on/off, press... VHF Low 25.00000 88.00000 1 AIR 108.00000 136.99166 2 VHF High 137.00000 174.00000 3 UHF 512.00000 4 400.00000 Band Plan 2 Range (MHz) Band Low High To turn a Close Call band on/off, press... VHF Low 25.00000 87.29500 1 AIR 108.00000 136.99166 2 VHF High 137.
• 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: • Close Call DND.
displayed frequency. Press Scan to resume scanning. Every 2 seconds, the scanner checks for frequencies in the Close Call band you specified (see page 39). LOCKING OUT CHANNELS AND FREQUENCIES You can skip any channel or up to 200 specified 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, or have static and interference.
Unlock Permanent Lock Out To 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 lockout 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 scanner beeps twice and CLEAr displays.
PRIORITY The Priority feature lets you scan through the channels and still not miss important or interesting calls on specific channels. There are three Priority options available in Scan or Scan Hold mode: • Priority Off (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 every 2 seconds only when it is not receiving transmissions.
DELAY Sometimes a user might pause before replying to a transmission. To avoid missing a reply on a specific 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 Specification Scan Each channel can be set individually. Search Custom Search: If one range is set, all ranges are set. Service Search: Each band can be set as a unit.
To turn off the 2-second delay, press Func + Dly while the scanner is monitoring a channel, scanning, or searching. DLY disappears. STEP FREQUENCY You can change Step Frequency. The scanner have some steps as 5.0/6.25/8.33/10.0/12.5/20.0 kHz and Default. Step Frequency is applied in Quick Search, Custom Search, AIR Service Search, and Close Call. Step Frequency is stored every each Band Coverage. 1. Press Func + Step, then indicates current Step Frequency. And F disappears, PGM appears. 2.
Channel Memory for Memory Channel Scan is able to store Modulation Type. 1. Press Func + Mod, then current Modulation Type changes. 2. Press Mod to choose a Modulation Type. Press Func, then F disappears. Note: If the scanner is turned off, modulation is set to initial setting.(For CB band and HAM band, the modulations are kept) 3.
