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

Typical repeater systems provide coverage out to about a 40 km radius from the repeater location.

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

WARNING! Set REG. ALK. BATT./NI-MH BATT. to NI-MH BATT. only if you are using rechargeable batteries. Never attempt to recharge non-rechargeable batteries. Non-rechargeable batteries can get hot or burst if you try to recharge them. 4. Install two batteries in the compartment as indicated by the polarity symbols (+ and -) marked inside.

Cautions: • 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. • Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities. 5. Replace the cover. 6. When flashes and the scanner beeps every 15 seconds, replace both batteries. Using Rechargeable Batteries You can also use two rec

WARNING! Do not connect either adapter to the scanner if non- rechargeable batteries (such as alkaline batteries) are installed in the scanner and REG. ALK. BATT./NI-MH BATT. is set to NI-MH BATT., or if you are unsure of the switch’s position. Non-rechargeable batteries will get hot and can even burst if you try to recharge them. Before you use Ni-MH or Ni-Cd batteries for the first time, charge them for 16 hours to bring them to a full charge. Discharged batteries take about 16 hou

Using AC Power You can power the scanner using an optional 6V, 500 mA AC adapter. To use the scanner on AC power, plug the AC adapter into DC 6V on the side of the scanner then plug the other end into a standard AC outlet. If rechargeable batteries are installed and REG. ALK. BATT./NI-MH BATT. is set to NI-MH BATT., the adapter powers the scanner and recharges the installed batteries at the same time.

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. Note: Always use 50-ohm, RG-58, or RG-8, coaxial cable to connect an outdoor antenna. If the antenna is over 15 metres from the scanner, use RG-8 low- loss dielectric coaxial cable. You can get a BNC adapter at your local electronics store. Connecting an Earphone/Headphone UBC72XLT For private listening, yo
