About Scanning
Introduction
Scanning
Options
Types of
Communicatjon
Scanning is easy and fun with the UBC144XLT 16-Channcl
Base Scanner. You can scan in 2 ways:
■ Scan channels you have programmed
■ Scan pre-programmed weather channels.
Unlike standard AM or FM radio stations, most 2-way
communications (sec "Types of Communication" below) do
not transmit continuously. The UBC144XLT scans
programmed channels at the rate of about 15 channels per
second until it locates an active frequency. When the
scanning stops on an active frequency, it remains on that
channel as long as the transmission continues. When the
transmission ends, the scanner stays on the channel for
2 more seconds, waiting for a responding transmission. If
no responding transmission is detected, the scanning cycle
resumes until another transmission is received.
You can to monitor communication such as:
■ Police and fire department
(including rescue and paramedics) .
■ Weather broadcasts
■ Bu sines s/industrial radio
■ Motion picture and press relay
■ Utility
■ Land transportation frequencies such as trucking firms,
buses, taxis, tow trucks, and railroads
■ Marine and amateur (ham radio) bands
■ And many more
Taking Proper Care of Your Scanner
Do not use the scanner in high-moisture environments such as the
kitchen or bathroom.
Avoid placing the unit in direct sunlight or near heating elements or
vents.
Unp>acking
Carefully check the contents against this list:
■ UBC144XLT Base Scanner
■ Telescopic Antenna
■ AC Adaptor (Model AC-144U)
■ This Operating Guide
If any items are missing or damaged, contact your place of purchase
immediately.
Read this Operating Guide thoroughly before operating the scanner.
Installation
Installing the UBC144XLT
AC Adaptor
Model AC-144U
1. Insert the DC plug end of the AC Adaptor into the AC 10 V jack on the
scanner.
2. Plug the AC Adaptor into any standard 240 VAC wall outlet,
3. Plug the Telescopic Antenna into the ANT. jack. Extend the antenna to its
full height. For UHF frequencies, shortening the antenna may improve the
reception.
4. Plug an optional external speaker (8-ohm) into the E)Cr.SP. jack.
Notes
■ If strong interference or electrical noise is received, relocate the scanner or
its antenna away from the source.
■ If you arc operating the scanner in the fringe area or need to improve
reception, use an optional 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 may be necessary for the optional antennas.
