INTERFERENCE
Your scanner might cause TV or radio
interlerence even when it is operating
properly. To determine it your scanner
is causing the interference, turn oil
your scanner. It the Intenerence goes
away, your scanner is causing it. Try
to eliminate the Interterence by:
- Moving your scanner away lrom
the receiver
- Connecting your scanner to an
outlet that is on a diiterent electri-
cal circuit lrorn the receiver
-Conlacting your local Fla-
dioShack store tor help
It you cannot eliminate the interter—
ence. you may be required to stop us-
Ing your scanner.
We recommend you record your scan-
nefs serial number here. The number
is on the scannefs back panel.

CONNECTING AN
ANTENNA
Connecting the Supplied
Antenna
You must install an antenna before
you can operate the scanner.
The supplied telescoping antenna
- helps your scanner receive strong lo-
cal signals. To instail the antenna.
screw it clockwise into the hole on the
scanner‘s top.
Connecting an Outdoor
Antenna
Instead ol the supplied antenna, you
can connect an outdoor base-station
or mobile antenna (not supplied) to
your scanner using a BNC connector.
Your local FladioShack store sells a
variety ot antennas Choose the one
that best meets your needs.
when deciding on a mobile or base-
station antenna and its location. con
sider these points:
- The antenna should be as high as
possible on the vehicle or building
- The antenna and its cable should
be as lar as possible lrom sources
of electrical noise (appliances,
other mdios, etc).
- The antenna should be vertical lor
the best performance.
To connect an optional base-station or
mobile antenna. lirst remove the sup~
plied antenna trorn the scanner. AI-
ways use 50-ohm coaxial cable, such
as RG-sa or FlG-a. to connect the
base-station or mobile antenna. For
lengths over 50 test. use FIG-8 low-
loss dielectric coaxial cable. ll the an-
tenna cable’s connector does not llt in
the ANT. jack. you might also need a
Molorola-to-BNC antenna plug adapt-
er. Your local RadioShack store car-
ries a wide variety ol coaxial antenna
cable and connectors.
Once you choose an antenna, lollow
the mounting instructions supplied with
the antenna. Then route the antenna‘s
cable to the scanner and connect the
cable to the ANT. jack on the back ol
the scanner.
Cautions:
- Do not run the cable over sharp
edges or moving parts that might
damage it.
- Do not run the cable next to power
cables or other antenna cables.
Warning: Use extreme caution
when you install or remove an out-
door antenna. It the antenna starts
to tail, let it got it could contact
overhead power lines. If the anten‘
na touches a power line, contact
with the antenna. mast, cabte, or
guy wires can cause electrocution
and death. Call the power compa-
ny to remove the antenna. DO
NOT attempt to do so yourselt,
CONNECTING POWER
Using AC Power
The scanners supplied AC adapter
lets you power the scanner lrom a
standard AC outlet. To connect power
to the scanner, insert the AC adapter‘s
barrel plug into the DC 12V jack on the
back oi the scanner, then plug the AC
adapter into a standard AC outlet.
Cautions:
~ The supplied AC adapter supplies
12 volts DC power and delivers
500 milliamps. Its center tip is set
to positive. and its plug properly
his the scanners Dc izv jack.
Using an adapter that does not
meet these specifications could
damage the scanner or the
adapter.
——————_—.—_
- Be sure to connect the AC adapter
to the scanner before you connect
it to an AC outlet. and disconnect
the AC adapter trorn the AC outlet
before you disconnect it lrom the
scanner.
Warning: Do not use the AC adapt-
er‘s polarized plug with an extension
cord receptacle unless the blades can
be luIIy inserted to prevent blade ex-
posure.
Using Your Vehicle‘s Battery
Power
if your AC power lails (during an
emergency, lor example), you can
power your scanner trom your vehi-
cle’s cigarette lighter socket With an
optional DC cigarette lighter power ca-
ble.
To connect an optional DC cigarette
lighter power cable. insert its barrel
plug into the 00 12V jack on the back
oi the scanner. then plug the power
cable into your vehicle's cigarette
lighter socket.
Cautions:
0 Il you use a DC cigarette lighter
power cable With the scanner, it
must supply 12 volts and at least
500 milliamps of DC automotive
power. Its center tip must be set to
positive. and its plug must cor-
rectly lit the DC 12V jack on the
back at the scanner. Using a
power cable that does not meet
these specifications could dam»
age the scanner or the power
cable,
- it you use a cigarette lighter power
cable and your vehicle's engine is
running. you might hear electrical
noise lrom the engine while scan
ning. This is normal.
Note: Mobile use at this scanner is
unlawiul or requires a permit in some
areas. Check the laws in your area.
CONNECTING AN
EXTENSlON SPEAKER
In a noisy area. an amplilied extension
speaker. positioned in the right place,
might provide more comlonable listen-
ing. Plug the speaker cable‘s 3.5 mm
(‘la-inch) plug into your scanner’s A
lack.
Note: Connecting an external speaker
disconnects the scanner's internal
speaker.
CONNECTING AN
EARPHONEI
HEADPHONES
For private listening. you can connect
an earphone or headphones with a
3.5 mm (Vi-inch) plug to the (\ jack on
the tram or the scanner. This automat-
ically disconnects the internal speak-
er.
Listening Safely
To protect your hearing. follow these
guidelines when you use an earphone
or headphones.
. Do not listen at extremely high
volume levels. Extended high-vol-
ume listening can lead to perma-
nent hearing loss,
Set VOLUME to the lowest setting
beiore you begin listening. After
you begin listening. adjust VOL-
UME to a comtortable level.
Once you set VOLUME. do not
increase it. Over time, your ears
adapt to the volume level, so a vol-
ume level that does not cause dis-
comlort might still damage your
hearing.
UNDERSTANDING YOUR SCANNER
Once you understand a few simple terms we use in this manual and familiarize
yoursell with your scanner’s features, you can put the scanner to work tor you. Vou
simply determine the type oi communications you want to receive, then set the
scanner to scan them.
A trequency is the tuning location 01 a station (expressed in kHz or MHz), To lind
active frequencies. you can use the search tunction.
You can also search the service-search banks, which are preset groups or tre-
ouencies categorized by type at service.
When you lind a frequency, you can store it into a programmable memory location
called a channel, which is grouped with your other channels in a channel-storage
bank. You can then scan the channel-storage banks to see it there is activity on
the trequencies stored there. Each time the scanner linds an active irequency, it
stays on that channel until the transmission ends,
A LOOK AT THE FRONT PANEL
Your scanner's keys might seem contusing at tirst. but this inlormalion should help
you understand each key's lunction.
Note: same ol the scanner‘s keys perform more than one lunclion and are marked
With more than one label. The steps in this Owner's Manual show only the label on

UNDERSTANDING
BANKS
Channel Storage Banks
To make it easier to identity and select
the channels you want to listen to.
channels are divided into 20 banks of
50 channels each. Use each channel-
storage bank to group frequencies.
such as those used by the police de-
panment, lire department, ambulance
services, or aircraft. For example, the
police department might use tour lre-
quencies. one tor each side of town.
You could program the police lrequen-
cies starting with Channel 1 (the first
channel in bank 1) and program the
tire department trequencies starting
with Channel 3t (the tirst channel In
bank 2),
Service Banks
The scanner is preprogrammeo with
the lrequencies allocated by public
satety, police. tire/emergency‘ aircraft.
and weather services. This is handy
tor quickly linding active lrequenctes
' instead ol searching through an entire
band (see "Searching Service Banks"
on Page t7).
UNDERSTANDING
TRUNKING
In the past. groups that broadcast tre-
quently. such as police departments,
were restricted to transmitting on just
a few lrequencies. This resulted in
heavy trattic and often required 2-way
radio users to wait tor a specilic tre-
quency to clear belore transmitting.
Trunked systems allow more groups
of 2-way radio users to use tewer ire-
quenctss, Instead ol selecting a we
citic lrequency to transmit on. a
trunked system chooses one ot sever-
al lrequencies when the 2-way radio
user presses PTT (push to talk). The
system automatically transmits the
call on that lrequency. and also sends
a code that identities that 2-way radio
usefs transmission on a data channel.
You can set this scanner to monitor
the data channel lrequency. so you
can hear both the call and response
transmissions for that 2-way radio
user and therelore tollow the conver-
sation. (You cannot listen to the data
channel itself in the trunk mode.)

TRUNK TRACKING
Your scanner is designed to track
transmissions on Motorola Type I,
Type II, and hybrid analog trunking
systems, which are extensively used
in 800 MHz communications Remem-
ber these important points when track-
ing transmissions:
~ Your scanner monitors Type ti sys-
tems by delault. However, you can
change this it the system in your
area is ditierent (see "Types ol
Trunking Systems" on this page
and “Scanning Type I and Hybrid
Trunked Systems“ on Page 34 lor
more information).
~ Your scanner cannot track trans-
missions on non-Motorola trunk-
ing systems.
- Your scanner tracks an 800 MHz
trunked system or scans trequen-
cies in conventional mode. but it
cannot do both at the same time,
TYPES OF TRUNKING
SYSTEMS
Your trunk tracking scanner can moni-
‘tor two basic types oi systems —— Type
land Type ll. Instead of selecting a
specific lrequency to transmit on, a
tmnked system chooses one oi sever-
al irequencies in a 2-way radio users
talk group when that user presses
PTT (push to talk). Thus, trunking sys-
tems allocate a lew lrequencies
among many difierent users, but the
way Type 1 and Type II systems do
this is slightly difierent. One important
distinction between these systems is
the amount oi data transmitted by
each radio when its PTI' button is
pressed. In a Type I system. the ra-
dio's ID and its current affiliation (the
trunk system it belongs to) are both
transmitted. In a Type II system, only
the radios ID is transmitted.
Why the dillerence? In Type I sys-
tems. each radio in the trunk group in-
dividually transmits its own alliliatton,
while the trunk system maintains a da-
taoase that determines each radio‘s
alliliation(s) in Type II systems.
Another dillerence between the sys-
tems is that Type I systems are ar-
ranged in a lleet-sublleet hierarchy
For example. it is possible tor a city
using a Type l system to designate 4
Ileets. each with B sublleets.
The tieets might be the police depart-
ment. the tire department, utilities, and
city administration. The police might
decide to lurther divide its fleet into
sublleets such as dispatch, tactical
operations, detectives, north, south.
east and west side patrols, and super-
visors. All the available police radios
would then be assigned to one oi the
police sublleets. letting the police cen<
tralize their communications and con-
trol the type oi users on a single
system Determining the exact ileet-
sublleet hierarchy tor a particular area
is relerred to as fleet map program-
Ming.
———_.—_—
The disadvantage ol 3 Type I system
is that the briet burst oI data sent
when a user transmits must contain
the radio’s ID and its Ileet and sub-
Ileet. This is three times the amount oi
data a Type II system radio sends.
Since the data capacity at Type I sys-
tems is limited and the amount of data
increases with each user. Type I sys-
tems usually accommodate fewer us-
ers than Type II systems. Never-
theless. Type I systems are still in use.
There are also hybrid systems which
are a combination oi both Type I and
Type It. Your scanner detaults to mon-
itor Type II systems, but you can
change to Type I or a hybrid oI Type t
and Type II systems by selecting a
preprogrammed Iteet map or creating
a custom Ileet map Ior your area (see
“Scanning Type I and Hybrid Trunked
Systems” on Page 34).
Vou do not need to determine the
Ileet-subtleet hierarchy Ior Type II sys-
tems unless you are tracking hybrid
systems that contain both Type I and
Type II systems.

your scanner sets up 5 scan lists into
which you can store your lavorite IDs,
Each list can contain up to to IDs, so
you can store a total or 50 tDs lor each
trunk tracking bank (500 IDs it you use
all banks as trunking banksl).
Scan lists help you organize tnmking
system users into categories. For ex-
ample. you might use List 1 lor police

SCANNING TYPE I AND
HYBRID TRUNKED
SYSTEMS
Your PRO‘ZOSO is set to scan Type II
user IDs by delault. When you scan
trunked lrequencies. each Type ll user
ID you see appears as an even num»
ber without a dash (such as 2160).
Your PRO-2050 can also scan Type I
trunked systems. Each Type I I0 ap-
pears as a three- or low-digit number,
lollowed by a hyphen, lollowed by a
one- or two-digit number (such as
200-14).
Il you notice a mix at odd- and even~
user IDS (such as 6477. 2160, 6431,
6144. and 1167). then you are proba-
bly monitoring either a Type I or hybrid
(a combination oi Type I and Type II
user IDs) system. (See “Types ol
Trunking Systems" on Page 25.)
You might also notice that you are
missing responses when you hold on
an active ID. Unlike Type II systems.
Type I and hybrid systems require a
lleet map that sets specilic lleetAsub-
lleet parameters. It is easy to select a
tleet map to scan; what is not always
easy is selecting or programming a
map that is being used in your particu-
lar area.
When a Type | system is designed,
the address iniormation Ior all its user
IDs is divided into 8 equal-size blocks,
numbered 0—7, and each block is as-
signed a size code. when you set up
your scanner to track a Type | system,
you must choose a size code tor each
block. When you have chosen a size
code (or all 8 blocks, you will have du-
plicated the fleet map lor the system
you are tracking. Il you have chosen
correctly, you will be able to track
transmissions in that system.
———__—
Each size code defines the number ol
lleets, sublleets, and IDs each block
has. For example, you can see in the
IoIIowing table that a size code ol 54
has one Ileet, which is divided into 15
separate sublleets, and it has a total
OI 512 individual IDs.

Each ID in the block is unique. The
left-most digit is the block number in
the ID. The next two digits identity
which lleel is active. and the last dig-
it(s) (alter the hyphen) identifies the
subfleet.
The size codes selected by a Type |
system designer depend on the spe-
citic needs ol the system's users,
Some organizations might want many
sublleets with only a lew radios each,
while another organization might want
only a lew sublieets, with many radios
each, To scan Type | systems. you
must select or program a Ileet map
with the same size code assignments
as the trunked system. It you do this
accurately. you will track all the lleet
and sublleet combinations used by the
system. In other words, you will hear
complete communications while moni-
toring a trunked system.
Note: www.1runkscanner,com plans to
make preset lleet maps available as
they become known.
It you do not already know the size
codes used, you will have to guess
them. But since you do not have to lig-
ure out all the blocks at once, this is
not as hard as it seems. Select a size
code tor a block, then press SEARCH.
Now listen to the communications. ll
you decide you are receiving most or
the replies to the conversations with
IDs assigned to the block you just pro-
grammed. then you have probably se-
lected the right size code and can
work on the next block oi the map.

on the voice channel. However, you
can manually turn on this lunctton so
the scanner does not tune to the data
channel when it receives a disconnect
tone on the voice channel.
Notes:
~ You can also manually set the
scanner so it always stays on the
voice channel (even when a dis-
connect tone is transmitted on that
channel or there is no signal at all)
by setting SOUELCN so you hear a
hissing sound,

Birdie Frequencies
Every scanner has birdie trequencies. Birdies are signals created inside the scan-
ner‘s receiver. These operating lrequencies might interfere with broadcasts on the
same trequencies. It you progmm one at these frequencies, you hear only noise on
that trequency. II the interterence is not severe, you might be able to turn SQUELCH
clockwise to cut out the birdie. This scanner's birdie trequencies (in MHZ) are:
171.25 406 7625 4073125 413.175 413225
To find the birdies in your indlvidual scanner, begin by disconnecting the antenna
and moving it away irom the scanner. Make sure that no other nearby radio or TV
sets are turned on near the scanner. Use the search Iunction and search every ire»
quency range lrom its lowest frequency to the highest. Occasionally, the searching
will stop as it it had found a signal. otten without any sound. That is a birdle. Make a
list or all the birdies in your scanner tor luture relerence.

FREQUENCY CONVERSION
The tuning location of a station can be expressed in lrequency (kHz or MHZ) or in
wavelength (meters). The lollowing lnlormation can help you make the necessary
conversions.
1 MHZ (million) = 1000 kHz (thousand)
To convert MHz to kHz, multlply the number ot megahertz by 1,000:
9.62 (MHZ) x 1000 : 9620 kHz
To convert lrom kHz to MHz, divide the number at kilohenz by 1,000:
2780 (kHz) «- 1000 = 2.780 MHZ
To convert MHZ to meters, divide 300 by the number OI rnegahenz:
300 e 7.1 MHZ = 42.25 meters
