• If you tune to a search skip fre-
quency, 
L/O appears. See “Lock-
ing Out Channels and Fre-
quencies” on Page 23.
• To skip data signals (such as
modem signals), press 
DATA. See
“Skipping Data Signals” on
Page 25.
SCANNING THE STORED 
CHANNELS
To begin scanning channels, press
SCAN. The scanner scans through all
non-locked channels in all banks that
are turned on, then stops on the first
transmission it finds. When the trans-
mission ends, the scanner resumes
scanning.
Notes:
 
• Channels with no...

ority channel (for up to a total of 10
stored channels). As the scanner
scans the bank, if the priority feature is
turned on, the scanner checks the pri-
ority channel for activity every 2 sec-
onds.
Changing Priority Channels
The scanner automatically desig-
nates each banks first channel as its
priority channel. Follow these steps to
select a different channel as the priori-
ty channel for a bank.
1. Press 
MANUAL.
2. Enter the channel number you
want to select as the priority chan-
nel, then press...

SPECIAL FEATURES
DELAY
Many agencies use a two-way radio
system that might have a period of 2
or more seconds between a transmis-
sion and a reply. To keep from miss-
ing a reply, you can program a 2-
second delay into any channel or fre-
quency. The scanner continues to
monitor the frequency for 2 seconds
after the transmission stops before re-
suming scanning or searching.
To program a 2-second delay:
• If the scanner is scanning chan-
nel-storage banks and stops on
an active channel where you want...

Locking Out Channels
To lock out a channel while scanning,
press 
L/O when the scanner stops on
the channel. To lock out a channel
manually, select the channel and
press 
L/O until L/O appears.
Note:
 You can still manually select
locked-out channels.
To remove the lockout from a channel,
select the channel and press 
L/O until
L/O disappears.
To remove the lockout from all chan-
nels in the channel-storage banks that
are turned on, press 
MANUAL to stop
scanning, then hold down 
L/O until the
scanner...

CHANGING SEARCH 
SPEEDS
The PRO-2052 has two search
speeds for a limit search.
To switch between the normal and Hy-
perSearch speeds during a limit
search, press 
SPEED. SEARCH flash-
es during HyperSearch.
Note: 
You can use HyperSearch only
in the 5 kHz step bands (29–54 MHz,
137–174 MHz, and 216–224.995
MHz). 
SKIPPING DATA 
SIGNALS
You can set the scanner so it skips
nonmodulated or data signals (such
as modem transmissions) during a
scan or search.
Note:
 Since data signals are not gen-
erally...

26
Each FIPS code identifies a specific
geographic area (defined by the Na-
tional Weather Service), so your scan-
ner sounds an alert only when a
weather emergency is declared in that
area. This helps you more efficiently
track the weather conditions in and
around your area.
When a Weather Alert Occurs
When the scanner receives a weather
alert:
• it sounds a series of beeps
• an indicator appears
The scanner also receives other
weather-related signals such as test
events (
TSt appears) and other
events...

on Page 28). For example, this lets
you avoid hearing an alert that applies
to an area within a 50-mile radius but
not necessarily to your county or par-
ish.
Note:
 If you do not program any FIPS
location codes into the scanner’s first
memory (F1), the scanner sounds an
alert if it receives a weather alert with
any
 FIPS code.
Obtaining Your Area’s
FIPS Code(s)
To obtain the FIPS code for the loca-
tion where you installed your scanner,
contact your local RadioShack store
or call the NWS toll free at...

series of beeps and L3 (if the broad-
cast is a statement), 
L2 (if the broad-
cast is a watch), or 
L1 (if the
broadcast is a warning) appears.
Once the scanner receives a SAME-
coded signal, it retains the information
in its memory. This information stays
in memory even if you change modes,
but is erased when you turn off the
scanner. You can switch to weather
search mode to check the alert level.
Entering Your Area’s FIPS 
Code(s)
1. Turn on the SAME alert function
(see “Turning on the SAME and...

Testing NWR-SAME Code 
Detection
1. Turn on the SAME alert function
(see “Turning on the SAME and
Weather Alert” on Page 27).
2. Hold down 
ALERT for about 3 sec-
onds. The selected frequency
number and 
TESt alternate on
the display. Then, when the scan-
ner receives a test code, 
TSt
appears.
3. Press 
ALERT to exit the test
mode.

TRUNK SCANNING
Your scanner is designed to track
transmissions on Motorola Type I,
Type II, GE/Ericsson EDACS, and hy-
brid analog trunking systems. Re-
member these important points when
tracking transmissions:
• Your scanner monitors Type II
systems by default. However, you
can change this if the system in
your area is different (see “Types
of Trunking Systems” on this page
and “Scanning Type I and Hybrid
Trunked Systems” on Page 40 for
more information).
• Your scanner tracks a trunked
system
