About Your New UBC 2500XLT
The UBC 2500XLT is a brand new state-of-the-art information
radiowith automatic scanning capabilities. Itcan store
frequencies such as police,fire/emergency, marine, air,
weather frequencies, and otherbroadcasts into20 banks of 20
channels each. The new Rotary Tuner feature enables rapid
and easy selection of channels andfrequencies. And with
AUTO STORE, you can automatically programany channel.
With the UBC 2500XL T, you can scan all 400 channels at
selectable speeds, including the super fast Turbo Scan. In
addition, the UBC 2500XL T has an automatic frequency-
sorting capability for faster scanning within each bank.
What is Scanning?
Unlike standard AM or FM radio stations, most two-way
communications (listed below) do not transmit continuously.
The UBC 2500XL T scans programmed channels at the rate of
nearly 100 channels per second (in Turbo Scan Mode), until it
finds an active frequency.
Scanning stops on an active frequency, and remains on that
channel as long as the transmission continues. When the
transmission ends, the scanning cycle resumes until another
transmission is received. An optional Delay can be set so that
the scanner stays on the channel for 2 more seconds, waiting
for another transmission before resuming scanning.

Feature Highlights
.Turbo Scan This lightning-fast technology enables
the UBC 2500XL T to scan and search nearly 100
channels or steps per second. Because the frequency
coverage is so large (see "Technical Specifications"
section for band listing), a very fast scanning system is
essential. That is why we combined our latest
technology -Turbo Scan - into the UBC 2500XL T.
. VFOControl (Variable Frequency Oscillator) Turn
the Rotary Tuner to select the desired frequency or
channel.
. 400Channels You can program each of these
memorychannels to store one frequency.
.20 Banks Each bank contains 20 channels, usefulfor
storing similar frequencies in order to maintainfaster
scanning cycles.
. 25 MHz - 1.3 GHz Indicatesthe range offrequencies
that can be searched within the bands of your scanner.
(Note: The frequency coverage is not totally
continuous from 25.0 MHzto 1.3 GHz.)
. PriorityChannelsYou can assign one Priority
Channel in each of Banks 1 through 10. Assigning
priority channels allows you to keep track of activity on
your most important channel(s) while monitoring other
channels for transmissions.
.Weather Channels Letsyour scanner function as a
weather information radio.

Setup
The UBC 2500XL T comes with a rechargeable Nickel-Cadmium
Battery Pack. When fully charged, this Battery Pack will
supply up to 5 hours of dependable use.
Before using the UBC 2500XL T for the first time, or whenever
the LOWBATTERYIndicator appears on the LCD display, you
should fully charge the Battery Pack.
Note: When the Battery Pack is Iow, the Low Battery
Indicator will start to blink. After about 10 minutes, the
scanner will shut itself off to prevent the battery from becoming
completely discharged.
Before charging, you must first install the Battery Pack
according to the steps below.
Installing the Battery Pack
1. Turn the On-OffNolume Control OFF.
I
2. Slidethe pack ontothe bottom of the scanner until it
clicks.
D
~
Charging the Battery Pack
1. Plug the AC Adaptor ICharger (AAD-2500U) into the
Charging Jack located on the back of the Battery Pack.
WARNING! Use only the supplied AC Adaptor/
Charger. Any other AC adaptor or external power plug
having over-voltage or reversed polarity can cause
overheating or damage to the circuitry.
Plug the AC Adaptor /Charger into a standard AC outlet.
2.

To fully charge the battery, leave the Adaptor/Charger
connected for 14 to 16 hours. Note: You can operate
the unit while the battery is charging.
3. When charging is complete, disconnect the Adaptor/
Charger from the AC outlet and from the Battery Pack.
Note: Disconnect theAC Adaptor/Charger from the unit
during apower failure.
Mounting the Flexible Antenna
Place the end of the antenna onto the BNC connector on top
of the scanner and turn clockwise until tight.
Installing the Belt Clip
Place the Belt Clip slightly above the mounti:lg area on the
back of the scanner, and press downward and in.

Scanning Overview
Note: Before operating the uac 2500XLTfor the first time,
make sureyou have fully charged the Battery Pack.
1. Beforeturning onthe scanner, rotatethe Squelch
Controlfully clockwise.
2. Turnthe scanner on by rotatingthe On-OttNolume
Controlclockwise until you hear a click.
3. Adjust the volumeto a comfortable listening level.
4. Turn the Squelch Control counterclockwise just until the
"rushing" noise disappears. At the squelch threshold,
any incoming signal just slightly stronger than the noise
will open the squelch.
Note: Whensquelch is open, you can hear the broadcast I
(scanning is stopped). If squelch is set too tight, that is, too far
counterclockwlse from the threshold point, astronger signal
is required to open the squelch. If squelch is set on apoint
clockwise from the threshold, you will hear aconstant sound
(noise, if no signal is present) The scanner will not scan.
The UBC 2500XL T has 400 memory channels, each of which
can be programmed to store one frequency. The channels are
divided into twenty 20-channel banks, useful for storing similar
frequencies in order to maintain faster scanning cycles.
You can monitor communication in one of two ways:
.Bank SCAN Ifyou haveprogrammedchannels,you'
can scan all programmed channels in the selected
bank(s), except locked out channels. When scanning
stops on an active frequency, it remains on that channel
as long as the transmission continues. If the Delay
Mode is on, the scanner remains on the same channel
for 2 more seconds, waiting for a responding
transmission. If there is no responding transmission
within 2 seconds, the scanning cycle resumes.
.Band SEARCH The Searchfunction is differentfrom
Scan. When you select a frequency band to search, the
scanner searches for any active frequency within the
lower and upper limits of the band. When an active
frequency is found, the scanner stops on that frequency
as long as the transmission lasts. If the Delay Mode is
on, the scanner remains on the same channel for 2
more seconds, waiting for a responding transmission. If
there is no responding transmission within 2 seconds,
the scanning cycle resumes.

-----

Programming Channels
Before you can scan, you must program the channels within a
bank. You can store one frequency per channel, up to 400
channels.
Each time you store a frequency, the list of scanning
frequencies in the bank is automatically sorted by frequency
number. This unique Auto Sort feature enables faster
scanning. When you manually step through a bank, however,
frequencies are sorted according to channel number.
With the UBC 2500XL T, there are a number of ways to program
a channel:
. Manually selecting a channel and frequency, using the
numeric keypad
. Using the Rotary Tuner to select a channel and
frequency
. Searching a band to find active frequencies, and then
storing them into channels
. Using the Auto Store feature to automatically program
channels
. Transfer a programmed frequency from another channel
Try each of the following programming methods, and then use
the one that's right for you!
A. Programming By Manual Entry
Before you begin, if "KEYLOCK"appears on the display, press
and hold [LCK] for 2 seconds to unlock the numeric keypad
and enable manual programming.
1. Select a frequency.
Example: Program 460.150 MHz into Channel 23.
Press [MANUAL] to stop scanning.
2.
3. Press [2] [3].
4. Then, press [MANUAL].
5. Enter the frequency number using the numeric keypad.
Note: Be sure to include the decimal point.
[4] [6] [0] [.] [1] [5] [0]
If you make a mistake and want to clear the entry, press
[.] twice and re-enter the correct frequency.
16
.-~L
==-=-=== =- -o.~'".=..=-.b -

--
6. Press [E] to store the entry.
.If the frequency is already stored in another
channel, the other channel will appear on the
display. To resolve the conflict, just enter another
frequency for the cu"ently selected channel.
(Later, we'll discuss how to delete astored
frequency.)
.Any frequency already stored in achannel will
automatically be replaced by the new one.
."Error" appears on the display if an e"or is made
during programming, or if the frequency is out of
range. To clear the error, enter avalid channel or
frequency number.
To program another channel, repeat the above procedures.
B. ProgrammingWiththe RotaryTuner
