To get the most from this manual, review the contents to become familiar with the basic functions available. If you are new to scanning, be sure to read “Understanding Scanning” on Page 11 for a quick background on the technology behind the hobby. The first thing you’ll need to do is install batteries in the scanner. Then you need to connect the included antenna to the scanner. See “Using Internal Batteries” on Page 15 and “Connecting the Antenna” on Page 19 if you need any help doing t

Understanding Scanning This section provides you with background on how Understanding Scanning 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 UBC72XLT. What is Scanning? Unlike standard AM or FM radio stations, most two- way communications do not transmit continuously. Your UBC72XLT scans programmed channels until it finds an active frequency, then stops on that frequency and remains on that

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 • PRS (UHF CB) users • Broadcast AM/FM/TV stations • Many business radio users When you want to store a conventional system, all you need to know is 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, th

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 40 km radius from the repeater location. Where To Obtain More Information By itself, this manual really only provides part of what you need to know to have fun scanning – how to program and use the scanner.

Setting Up Your Scanner These guidelines will help you install and use your new scanner: • If your scanner receives interference or electrical noise, move the scanner or its antenna away from the source. • To improve the scanner’s reception, use 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. A mating plug might be necessary
