RadioShack Pro 2052 Vhf Uhf Scanner Reciever Owners Manual

Each ID in the block is unique. The
left-most digit is the block number in
the ID. The next two digits identify
which fleet is active, and the last dig-
it(s) (after the hyphen) identifies the
subfleet.
The size codes selected by a Type I
system designer depend on the spe-
cific needs of the system’s users.
Some organizations might want many
subfleets with only a few radios each,
while another organization might want
only a few subfleets, with many radios
each. To scan Type I systems, you
must select or program a fleet map
with the same size code assignments
as the trunked system. If you do this
accurately, you will track all the fleet
and subfleet combinations used by the
system. In other words, you will hear
complete communications while moni-
toring a trunked system.
Note:
 
www.trunkscanner.com plans to
make preset fleet maps available as
they become known.
If you do not already know the size
codes used, you will have to guess
them. But since you do not have to fig-
ure out all the blocks at once, this is
not as hard as it seems. Select a size
code for a block, then press 
SEARCH.Now listen to the communications. If
you decide you are receiving most of
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 of the map.
There are 16 preset fleet maps to
choose from, and it is best to start with
these when setting up a Type I or hy-
brid trunk scanning bank. If none of
the following preset fleet maps allow
you to follow complete conversations,
then you probably need to program
your own fleet map (see “Program-
ming a Fleet Map” on Page 44).

Selecting a Preset Fleet Map
1. Set the scanner for conventional
scanning, then hold down 
TRUNK
until the scanner beeps twice.
BANK, TRUNK, and the bank
numbers flash.2. Press a number key to select the
bank where you want to store the
preset fleet map.
3. Repeatedly press s
 or t
 to select
E1 (Type I and hybrid), then press
E. 
4. Press 
DATA.
5. Repeatedly press s
 or t
 to select
the name of the desired map
(such as 
E1P7), then press E.
The scanner then searches for trans-
missions using the preset map you
chose.
Note:
 When the scanner searches for
transmissions, you see Type I fleet
and subfleet IDs such as 
100-12,
100-9, 000-12, or 400-8. 
How do you know if the preset map
you selected is correct? Listen to see
if you are following complete conver-
sations. If not, try another preset map.

Programming a Fleet Map
1. Set the scanner for conventional
scanning, then hold down 
TRUNK
until the scanner beeps twice.
BANK, TRUNK, and the bank
numbers flash.
2. Press a number key to select the
bank where you programmed
Type I trunk frequencies.
3. Repeatedly press s
 or t
 until 
E1
appears, then press E
.
4. Press 
DATA.
5. Repeatedly press s
 or t
 until
USr appears, then press DATA.
6. Repeatedly press s
 or t
 to select
the size code for the first block,
then press 
E. The next available
block appears.
7. Repeat Step 6 until you have
selected a size code for each
block you want to work with.
8. Press 
SEARCH. The scanner exits
the trunking programming mode,
tunes the data channel, then
begins to search using the map
you programmed.
Note: 
If you select size code S12,
S13, or S14, these restrictions apply:
• S12 can only be assigned to
Blocks 0, 2, 4, or 6.
• S13 can only be assigned to
Blocks 0 and 4.
• S14 can only be assigned to Block
0.Since these size codes require multi-
ple blocks, you will be prompted for
the next available block when pro-
gramming a fleet map. For example, if
you assign Block 0 as an S12, the
scanner prompts you for 
b2, the next
block available, instead of 
b1. And if
you assign Block 0 as an S14, you
would not see another prompt be-
cause it uses all available blocks.
Programming a Hybrid 
System
A hybrid system is simply a Type I
system with some of its blocks desig-
nated as Type II blocks. To program a
hybrid system, follow the steps listed
in “Programming a Fleet Map” on
Page 44. However, if you want a block
to be Type II, select size code 
S0 in
Step 6.
Programming the Base and 
Offset Frequencies
To properly track Motorola VHF and
UHF trunked systems, you must pro-
gram the applicable 
base and offset
frequencies for each system.
These settings can be found at
www.trunkscanner.com and similar
frequency resources.
1. Set the scanner for conventional
scanning, then hold down 
TRUNK
until the scanner beeps twice.
2. Press the number key of the bank
where you want to store the base
frequency.

3. Repeatedly press s
 or t
 to select
E2-Hi or E2-UHF, then press E.
4. Press 
DATA. The preset base fre-
quency appears.
5. Enter a desired frequency, then
press 
E.
6. Press 
DATA. The preset offset fre-
quency appears.
7. Enter the frequency using the
number keys according to the fol-
lowing guide, then press 
E:
• For Motorola Type II VHF, (E2-
Hi band) use 5 kHz steps
between 5 kHz–100 kHz.
• For Motorola Type II UHF, (E2-
UHF band) use 12.5 kHz steps
between 12.5 kHz–100 kHz.
Note:
 For example, if you pro-
gram 406.0250 as a trunked fre-
quency, the base and offset
frequencies are as follows:
• BASE: 406.0000 MHz, OFFSET:
12.5 kHz=Channel 2
• BASE: 406.0000 MHz, OFFSET:
25.0 kHz=Channel 1
8. Repeat the steps under “Program-
ming Trunked Frequencies” on
Page 32 to store the trunked sys-
tem’s frequencies in your scan-
ner’s banks.
Turning the Motorola 
Disconnect Tone Detect 
Function On/Off
While trunk scanning a Motorola sys-
tem, your scanner automatically tunes
to the data channel when it detects a
disconnect tone (a code that tells the
trunking system that the transmitter
has finished sending) on the voice
channel. 
You can manually turn off this function
so the scanner does not tune to the
data channel under those conditions.
Use this feature to listen to weak
transmissions when conversations are
generally disconnected.
To turn the disconnect tone detect
function off, set the scanner to trunk
track then press 
SVC. The scanner
beeps and   flashes for about 5
seconds.
Notes:
• To set the scanner so it remains
on the voice channel (even when
a disconnect tone is transmitted or
there is no signal at all) set
SQUELCH so you hear a hissing
noise.
• You cannot use the disconnect
tone detect function if you are pro-
gramming a trunking frequency or
a fleet map.
To set the scanner to automatically
tune to the data channel once again
when it detects a disconnect tone,
press 
SVC.   disappears.

PC REMOTE FUNCTION
Your scanner’s PC Remote function
lets you connect the scanner to a
computer then use the computer to
operate most of the scanner’s func-
tions, the same way as if you were us-
ing the keys on the scanner’s front

CONNECTING THE 
SCANNER TO A 
COMPUTER
Caution
: Always turn off the computer
before connecting or disconnecting
your scanner. Otherwise you could
damage your computer or the scan-
ner. 
To connect the scanner to your com-
puter, plug one end of an optional 9-
pin serial cable (available at your local
RadioShack store) into 
REMOTE on
the back of the scanner, then plug the
other end of the cable into your com-
puter’s serial port.
SETTING THE REMOTE 
COMMUNICATION 
FORMAT
To set the remote communication for-
mat so the scanner and computer can
communicate with each other, use
standard Windows communications
software (such as Modem Master or
Hyper Terminal, not supplied). See
your software’s documentation for
more information about operating it.
Software Settings
Use the following settings for the com-
munications software.
