INTRODUCTION Thank you for purchasing a Uniden UBC125XLT 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.

Close Call Do-Not-Disturb - checks for Close Call activity in between channel reception so active channels are not interrupted. Close Call Temporary Store - temporarily stores and scans the last 10 Close Call hits in the Close Call Hits bank. PC Programming - you can download information into the scanner and upload to the scanner via your personal computer.
Page 8
Priority Scan with Do Not Disturb - lets you program one channel in each bank (10 in all) and then have the scanner check each channel every 2 seconds while it scans the banks so you don’t miss transmissions on those channels. Do-Not Disturb keeps the scanner from interrupting transmissions during receiving.

Modulation - Lets you select a modulation (AM or FM) each band coverage band. Display Backlight - You can turn on/off the LCD backlight, set it operate on squelch only, keypress only, or both. Signal Strength Meter - shows the signal strength for more powerful transmissions.
Battery Low Alert - the icon will blink in the display and a tone warns you every 15 seconds when the battery power gets low. FREQUENCY RANGE This table lists the frequency ranges, default step frequency, default modulation, and type of transmissions you can hear for each range.
WHAT IS SEARCHING? The UBC125XLT can search for active frequencies. This is diff erent from scanning because you are searching for frequencies that have not been programmed into the scanner.
UNDERSTANDING SCANNING What is CTCSS/DCS? Your scanner can monitor systems using a Continuous Tone Coded Squelch System (CTCSS) and Digital Coded Squelch (DCS) system, which allows the squelch to open only when the tone you have programmed with a specifi c frequency is received along with a transmission.
with a signal, the scanner’s squelch remains closed and you hear nothing. Refer to the Reference section of this manual for tables showing the available CTCSS frequencies and DCS codes. 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).
construction job sites, and with inexpensive consumer radios such as PMR radios. The range is typically 1-8 miles, depending upon the terrain and many other factors. 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.
searches that can be used just like the channel storage banks to search these frequencies in Service Search mode. Custom Search Banks Custom Search Banks let you program and search 10 custom search ranges. During custom search, the scanner starts searching with the lowest frequency in the search range you select to the highest frequency in the range.
CONNECTING 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. Connecting an Optional Antenna 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.
You can power the scanner using alkaline (ALK) non- rechargeable batteries (not supplied) or the included Nickel Metal-Hydride (Ni-MH) rechargeable batteries. [Uniden provides a USB cable to charge the Ni-MH batteries on initial installation and to recharge them through your computer or through a power adapter that provides USB charge power.]...
• Always remove old or weak batteries. Batteries can leak chemicals that destroy electronic circuits. • Do not mix old and new batteries, diff erent types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of diff erent capacities. • Do not use and charge Ni-Cd batteries; this may cause a safety hazard and damage the scanner.
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/ubc125xlt . These will also be available on the CD’s with ARC125 Software.

ABOUT YOUR SCANNER We use a few simple terms in this manual to explain the features of the scanner. Familiarize yourself with these terms and the scanner's features, and you can put the scanner to work for you right away. Simply determine the type of communications you want to receive, then set the scanner to search those communications.
GETTING TO KNOW THE SCANNER If your scanner's keys seem confusing at fi rst, the following information should help you understand each key's function. Your scanner's keys have various functions labeled on the key tops and below the keys. The keys operate in Normal mode and Function mode.
