Page 6: Introduction
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. - Page 7 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.
- Page 8 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.
- Page 9 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 Confi rmation Tones - the scanner sounds a tone when you perform an operation correctly, and an error tone if you make an error.

Page 13: Scanning Basics
Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. Your UBC75XLT scans programmed channels until it fi 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. -
Page 14: Conventional Scanning
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. -
Page 15: Repeater Operation
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. -
Page 16: Custom Search Ranges
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. -

Page 18: Setting Up The Scanner
SETTING UP THE SCANNER Connect the Antenna Align the slots around the antenna’s connector with the tabs on the scanner’s BNC connector. Slide the antenna’s connector down over the scanner’s connector. 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. -
Page 19: Connect An Optional Earphone/Headphone
Connect an Optional Earphone/Headphone For 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 Speaker In a noisy area, an optional extension speaker, positioned in the right place, might provide more comfortable listening. -
Page 20: Installing Non-Rechargeable Batteries
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 fl ashes in the display and the scanner beeps every 15 seconds, recharge or replace the batteries. -
Page 21: Usb Connection
Make sure the power is turned off . Slide the battery compartment cover off . Use a pointed object such as a ballpoint pen to set the battery selection switch inside the compartment to Ni-MH. Install two batteries in the compartment as indicated by the polarity symbols (+ and -) marked inside the battery compartment. - Page 22 Note: If you connect to a computer’s USB port, the PC will prompt you for the drivers for your scanner.

Page 23: Low Battery Alert
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. -
Page 24: Adjust Squelch
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. -

CARE AND MAINTENANCE RESETTING THE SCANNER If the scanner’s display locks up or stops operating properly, you might need to reset the scanner. CAUTION: This procedure clears all the information you have stored in the scanner. Before you reset the scanner, try turning it off and back on to see if it begins working properly. -
Page 52: Cleaning
• If the scanner receives strong interference or electrical noise, move it away from the source of the noise. If possible, a higher elevation might provide better reception. CLEANING Keep the scanner dry. If it gets wet, wipe it dry immediately. Use and store the scanner only in normal temperature environments. -
