The fleets might be the police depart-
ment, the fire department, the utilities,
and city administration. The police
might decide to further divide its fleet
into subfleets such as dispatch, tacti-
cal operations, detectives, north,
south, east, and west side patrols, and
supervisors. All the available police ra-
dios would then be assigned to one of
the police subfleets, letting the police
centralize their communications and
control the type of users on a single
system. Determining the exact fleet-...

We recommend you set SQUELCH to
the position shown here before select-
ing a trunked bank.
Note:
 Change this setting as neces-
sary to get the best performance in
your area.
PROGRAMMING 
TRUNKED 
FREQUENCIES
Before you program your scanner to
track a trunked system, consider the
following:
• Valid trunked system frequencies
are as shown below.
Motorola system:
935.0125–939.9875 MHz
(in 12.5 kHz steps)
851.0000–868.9875 MHz
(in 12.5 kHz steps)
406.0000–512.0000 MHz
(in 12.5 kHz steps)...

4. Use the number keys to enter the
trunked system’s frequencies,
then press
 E.
Note:
 If you entered an invalid fre-
quency, the scanner beeps, the
channel number flashes and
Error appears. Press CLEAR to
clear the frequency, then repeat
Step 4.
5. Press either 
MANUAL or s
 to
select the next channel in the
bank.
6. Repeat Steps 4 and 5 until all fre-
quencies have been entered.
SCANNING A TRUNKED 
BANK
You can scan one trunked bank at a
time. Once you have stored frequen-
cies for a trunked system...

34
Hint:
 While scanning, you will not
know exactly whom the talkgroup IDs
are assigned to until you listen awhile
or until you locate talkgroup ID lists in
frequency guides or on internet sites
such as www.trunkscanner.com. With-
in a few minutes, you can usually fig-
ure out if what you are listening to is a
police, fire, or emergency medical 2-
way radio user. Other talkgroup IDs
might take some time, but determining
whom each ID represents is half the
fun of trunk scanning!
Turning Banks On or Off...

35
Follow these steps to turn status bit ig-
nore on or off.
1. Hold down 
SCAN until the current
status bit ignore setting (
ON or
OFF) appears.
2. Press s
 or t 
to select 
ON or OFF,
then press 
E.
Identifying a Trunked 
Frequency 
To identify a trunked frequency, press
t
 when the scanner stops on a talk-
group ID. The trunked frequency brief-
ly flashes twice. To show the fre-
quency longer, hold down t
. The
scanner beeps, then the trunked fre-
quency and talkgroup ID alternate.
Switching EDACS...

36
Note:
 If you consistently miss re-
sponses even with trunk scanning
scan delay set, you might need to
change the default system type or the
fleet map you are using. See “Scan-
ning Type I and Hybrid Trunked Sys-
tems” on Page 40.
Monitoring an Active ID
When the scanner stops on a trans-
mission, follow these steps to hold the
scanner on that transmission. 
Note: 
You can also follow these steps
to hold on an ID while scanning a scan
list. See “Scan Lists” on Page 37.
1. Press 
HOLD. HOLD appears...

37
MONITORING IDS
You can use your scanner’s display to
monitor the frequencies in a trunked
system for activity. You cannot hear
conversations in this mode, but this is
an excellent way to determine which
talk groups are the most active.
To set the scanner to monitor IDs,
hold down 
SEARCH until the scanner
beeps twice. 
SEARCH flashes, and all
talk group IDs appear in succession.
To stop monitoring IDs, press
SEARCH again.
Note: 
When you monitor IDs, locked-
out IDs also appear.
CHANNEL ACTIVITY...

38
Scan lists help you organize trunking
system users into categories. For ex-
ample, you might use List 1 for police
IDs, List 2 for fire department IDs, List
3 for emergency medical service IDs,
and so on. Once IDs are stored in
lists, you can scan them like you scan
conventional channels. You can pro-
gram IDs into scan lists manually, dur-
ing a search, or automatically.
Manually Storing IDs into 
Scan Lists
1. Select the desired trunking bank
(see “Scanning a Trunked Bank”
on Page 33).
2. After the...

Automatically Storing an ID in 
a Scan List Location
To store an ID in the first available
scan list location during a search,
press 
E at any time after the scanner
stops on that ID.
Or, follow these steps to store an ID in
a specific scan list location.
1. Press 
PRIORITY when the desired
ID appears.
2. Repeatedly press s
 or t
 to
choose a specific scan list loca-
tion. 
3. Press 
E.
Note:
 An ID you enter into a scan list
location automatically overwrites any
ID that is already stored in that...

40
Press PRIORITY to turn on priority
scanning. 
Note:
 Priority scanning does not work
if the ID is locked out.
SCANNING TYPE I AND 
HYBRID TRUNKED 
SYSTEMS
Your PRO-2052 is set to scan Type II
user IDs by default. When you scan
trunked frequencies, each Type II user
ID you see appears as an even num-
ber without a dash (such as 2160).
Your PRO-2052 can also scan Type I
trunked systems. Each Type I ID ap-
pears as a three- or four-digit number,
followed by a hyphen, followed by a
one- or two-digit...
